First, even though manufacturers might be rushing things, considering their last lovechild, Blu-Ray discs, hasn't really taken anything by a storm, let alone a slight tropical depression, there are some consumer-friendly caveats to consider before grinding those teeth in anger.

Take price, for example. HDGuru predicts set prices will be largely in line with current HDTV offerings. Initial pricing for a 40-inch 3D-ready 240Hz LED LCD will check in at about $1300, whereas a similar non-3D set from Samsung is currently for sale is $1,250.

The other elephant in the room, as least when it came to HD, is programming. While full-time HD programming has been around since HD Net launched in September 2001, it took until the end of the decade before this particular TV watcher could safely say all he watches on TV anymore are HD-only channels. Luckily—if you like where 3D is going anyway—that shouldn't be a problem for 3D in the 2010s. HDGuru assures us that the influx of PS3s on the market, coupled with 50 DirectTV 3D channels before the end of 2010, will ensure there's ample 3D TV available for the new sets that Sony, et al, will demand you buy for the best viewing experience. Sports, the original driver of HD content, will also come into play here, no pun intended.

As for HDTVs, 3D aside, the future is unsurprisingly cheaper, thinner and more portable. That's kind of how tech works, and beyond 2010 you can expect to see an influx of thin, LED edge-lit TVs that go larger than 60-inches. On the opposite end of the spectrum, expect more Zunes. That is, "Zune" in the sense that portables sporting HD visuals will become ubiquitous—who knows what fate will befall Microsoft's shiny player.

Lastly, this one's for Mark Wilson, who got headaches watching a great Avatar flick in 3D: HD glasses might eventually become unnecessary. At an expected $70 a pair, they won't be missed, but this prediction may take a while and will arrive first in the form of a single-viewer laptop at the end of 2010.

Again, predictions all. Nothing firm, but nothing too unbelievable either. There are more at HDGuru to parse and dissect and flame. Why don't you leave a few of your own in the comments? [HDGuru]

If you're unfamiliar with the Ambilight technology, it's a backlight system in some Phillips televisions where the color of the screen is transmitted to LEDs behind the television set, so that the background lighting matches the color on the screen. Fans of the technology claim it reduces eyes strain and enhances the theater experience.

DIYer Fun3 wanted to recreate the effect on his television. His solution was to wire an Arduino to a series of LED strips and and control the color by a USB cable hooked up to his HTPC. Check out the video below to see it in action.

Check out his site for schematics, code, and a ton of tips and tricks for calibrating your LEDs to your home theater. If you've experimented with back lighting your home theater—color changing or otherwise—let's hear about it in the comments.

If XpanD, the company behind the 3D glasses for Avatar is anything to go by, the price of fancy shutter glasses will start at around $70 a pair, and top out at around $150. XpanD claims that two pairs of their glasses will be bundled with 3D sets from Panasonic, LG, Sony and Vizio due out next year. The additional costs kick in when you need to buy extra pairs.

The mock up above is just a glimpse of what XpanD has planned, but rest assured, you will probably look like an idiot until technologies that don't require glasses come into their own. [DVICE]

The winter months are the hardest time to not want new stuff. We're inundated with sales, and in a few short weeks we'll be ogling next year's tech at CES. As the resident Gizmodo "no I won't upgrade my PowerBook" curmudgeon, I'm here for support. Take a look at the gear I use, and how despite its age, all (well, most of) it has plenty of life left.

I Call Him FrankenPod

No, you're not seeing things. The image above is indeed a picture of my primary media player, and yes, it is an iPod mini.

Go ahead, get the Borat jokes out of your system.

Done? Okay, now hear me out. Don't judge a book by its cover. As far as I'm concerned, this little guy can blow away nearly any other MP3 player on the market.

Under the hood, I swapped the 6GB microdrive with a 16GB Compact Flash card. I can easily change it out for a 32 or a 64GB card once prices come down. It's also running what I consider to be the most feature-rich firmware around, Rockbox. What looks like a beat-up iPod mini is actually a robust, nearly indestructible flash-based portable audio player, all built for a fraction of what a new one costs.

The mini isn't the only old iPod that's easily moddable. Considering about 118% of the United States' population has an old iPod lying around somewhere by now, chances are you've got what you need for a fun weekend project. Even if your heart's set on the Zune HD's OLED display or the Touch's app catalog, some love and a little elbow grease can breathe old life into that old iPod, and give you a great secondary PMP.

The Little Computer that Could

When I walked into Gizmodo HQ on my first day, I was nervous. Some of that anxiety was the new job jitters, but I was mostly afraid that my 12" PowerBook wouldn't cut it. Gizmodo moves fast, and my aging machine certainly doesn't. I was on the verge of upgrading, but decided to see how my old hardware fared before taking the plunge.

Long story short: It did the job. Barely. But through compromise, I made it work. I love Firefox and all of its extensions, but Safari runs at half the resource load. Photoshop Elements does what I need without the huge footprint of CS. With a little thought as to what applications I was running, which ones I didn't need, and where I was willing to compromise, my plucky PowerBook and I made it through the summer.

As much as I love the little guy, it's not like I haven't thought about replacing him. I almost pulled the trigger on a new MacBook last month. At the last minute I decided that instead of buying a computer that would last me 2-3 years, I wanted another that could feasibly last for 4+. Whenever that computer comes out, I'll probably bite, but until then I'm happy squeezing a little extra life out of my aging hardware.

Look at how you use your computer. If you're rendering all day, never leave Photoshop, or doing any other heavy computing and you need the speed, then upgrade. But the rest of us can probably hold off a little longer, even tech-obsessed gadget bloggers.

Nice Peeling Chrome Paint, Dude

I'm fairly certain I'm the only writer at Gizmodo without a smartphone. Yes, dumbphones must die, and someday I will upgrade this one. But for now, it makes calls, texts, and even has an almost acceptable music player built in that works in a pinch. Google services run surprisingly well in a WAP browser, too, so I can get email and read my RSS feeds when necessary.

Would I love to have a smartphone? Sure. (Hey Brian Lam and Jason Chen, skip down a few sentences) But it's also really nice to be disconnected sometimes. My Gizmodo email account receives a very steady stream of emails, to say the least. I like being able to walk away from the computer and cut myself off every once in a while, without my phone constantly reminding me that there's work to be done (Okay overlords, you can read on from here).

Just Because it's Old Doesn't Mean it Sounds Worse

No, this stereo doesn't do DTS-HD Master Audio. It has zero HDMI ports. But it still does 2-channel audio pretty well, more than well enough for what I need it to do.

Repurposing old stereo equipment is one of the best ways to build a great system on the cheap. The turntable and receiver are my dad's old gear, coupled with a pair of speakers I yanked off of a CD player I've had since I was 14. The setup won't win me any audiophile cred, but it definitely does a much-better-than-OK job at playing music.

Not to mention that it's pretty cool to listen on the same equipment my dad once used. When I was 17, I found his old record collection in the basement and immediately started spinning it on his long-forgotten turntable. Call me corny, but I think it's pretty awesome to know that 30-some years ago he was listening to the same records on the same deck.

If you aren't lucky enough to have access to your parents' old stereo equipment, it's not uncommon to find some real gems at your local thrift shop on the cheap, tossed away by someone who thought McIntosh is a cheap Apple knock-off.

Okay, so Maybe I Want to Upgrade Some of It

I do have one thing that I desperately want, and will upgrade to soon: an HDTV. I've never owned anything besides tube TVs under 20 inches. The fact that flat-panel prices are finally reasonable, combined with the digital switchover makes it prime time for me to jump the CRT ship.

I want to say that it always makes sense to hold onto your old TV after you upgrade, but in this case it might not. Television sets were at their saturation point well before HDTVs came along. In 2009 there were more TVs per household than people. By now it's likely that you just don't have room for a fourth or twelfth tube anywhere.

If you find yourself needing to dispose of an aging TV, please do so properly. Donate it. Sell it on Craigslist. Or look into electronics recycling centers in your area. An old TV may not have a place in your house or apartment, but it might find a place in someone else's home. It certainly doesn't belong in a landfill.

See? I'm Not a Total Luddite

I might roll with old stuff, but I'm not some sort of quasi-neo-luddite. Plenty of other gadgets in my arsenal are much more recent than what you see here. I have a PS3, my music gets fed to my stereo through a Squeezebox, and I do have another receiver that handles multichannel audio, albeit a relatively cheap and older one (and in case you're wondering, I did take these pictures with a DSLR, but it's not mine).

So yes, even I don't always live by the "never upgrade" mentality. Planned obsolescence and the industry's fast pace make it impossible to live by that creed. But I also think that a lot of the time we feel "forced" to upgrade we're really being driven by gadget lust, that powerful desire which makes us overlook the benefits of using old stuff.

Here's what I always think about when that ol' familiar "gotta have it" feeling hits. The biggest and most obvious perk: buy new stuff less often, save money. I don't know about you, but if I walk away from a big purchase, I feel like I've won. It's like trapping money that was trying to escape from my bank account. And if you've got a bit of the tree-hugging hippy spirit in you, you'll feel good about cutting down on your e-waste output, even if only by a little bit.

Not to mention the freedom old gear provides. I imagine it's similar to the feeling of operating the Mars rovers. I know that my gadgets have gone far beyond their planned mission length, so I throw them around without caring if they get damaged. And once that old gear inevitably goes belly up, I'll feel no remorse upgrading something that lasted for so long.

But that doesn't mean I won't be sad to lose my gadgets. I've heard other tech junkies say that we should never fall in love with technology, because we'll just end up heartbroken when it's time to say goodbye. In my opinion, that emotional connection is exactly what we need nowadays. If we all try to love our gadgets, to start treating them more like companions than disposable tools, a lot more perfectly good gear could be saved from an untimely retirement.

I know more than a few of you out there are eyeing some new toys for the holidays. I am too. But before we let upgraditis get the best of us, let's consider what we already have. Maybe it's still good enough. Maybe there's a new part that could make our gadgets better and provide a fun modding project to boot. Take it from me: There's almost always some way to squeeze extra life out of old gear.

Now, if you'll excuse me, there's an old Dell tower around here somewhere that's begging to become a NAS.

The Price

$150 as tested, for a 40-42" screen.

The Verdict

If you had a very nice TV and a very naughty child, I could see the appeal of TV armor.

The hardest part of installation is pulling the plastic film off the TV armor itself. Once that's done, you stick a few felt adhesive pads on the back, then set the armor directly over your television (it hooks from the top).

Even without the straps, I found the shield extremely well-balanced. That is, before I proceeded to bang the crap out of it with my remote. I basically tried to stab my Samsung to death with a blunt DirecTV remote. And I failed (which was a good thing).

While I'm not sure it could withstand a brick coming straight at it, TV Armor didn't flex enough to contact my TV's real glass screen at all during my remote test. However, the armor wasn't left completely unscathed. Some of the remote's plastic left little spots on the screen (and items like keys are sure to scratch the surface). But, I guess if you were investing in the product, you'd want it damaged rather than your TV.

As for glare and general watchability, it roughly doubles reflections coming off the screen. I found the sacrifice adequate, though depending on your precise lighting situation, results may vary. (The glare off a fully open window can get pretty intense at certain angles.)

So it's your call. But if I may be as bold as to suggest, for $130, the money spent on TV Armor could buy a lot of Ritalin and child muzzles. [TV Armor]

Solid construction

Minimal effects on overall image quality

Once it scratches, does that defeat the point or completely justify the device?

Increases glare moderately

From there, out of sight and mind, the EdgeCenter supports up to four TV tuners and 7.1 audio surround. It's configurable, with processor options ranging from Core2 Duo to two-way Core i7's. Windows 7 and a "durable" aluminum chassis come standard, as does the high $4,000 starting point. Add some options and that price point can go much, much higher. [Piixl via Engadget]

You see, the televisions in a few of these bundles never really sold for as much as Best Buy says they did, meaning the "steep discounts" are anything but. There's some savings to be had here, definitely, but even so six of the twelve TVs sold through this promotion were never actually offered for full price by Best Buy.

Here's just one example from HD Guru (emphasis theirs):

Sony KDL-46Z5100 46″(sku #9279899): $2,099.99 TV + $299.99 PS3 System + $59.99 PS3 Game + $29.99 Blu-ray Movie = $2,489.96 Regular Price – $410 TV Savings – $428.98 Package Savings = $1,650.98 Package Price

Current TV price is $1689.99. This TV never sold at BB for the MSRP of $2099.99

However, tucked in amongst the 12 bundles are a number of good deals. Just be careful when shopping around to be sure the one you've selected is really saving you a bundle. Price check against Amazon, here, or elsewhere first. The sale begins today and lasts through December 12. [HD Guru - Thanks, Gary]

HDTVs and Monitors

This is the number one cleaning question I get from friends and family, and it's one of the simplest to answer. HDTVs and monitors are the worst kind of dirt magnets, begging to be touched—by your boss who wants to show you something on your computer screen, by your greasy little cousin who's getting restless during his umpteenth viewing of Finding Nemo, by your drunk old buddy from college who somehow still thinks it's funny to grope actresses onscreen on his way to the bathroom—and sitting in total vulnerability: in the case of your LCD screen, within sneezing range; in the case of your flatscreen TV, in your dusty living room.

The tempting, nearly instinctual response to a oily, dusty, mucousy panel of glass or glasslike material is to reach under the sink, grab that bottle of Windex and the paper towels and spray that stuff down. Do not do this. There are some TVs and displays for which Windex will do the job—CRT televisions, for example, and some glass-paneled screens—and if you've been using Windex in the past without incident, don't worry too much. But also, stop.

Spraying any kind of cleaner onto a screen isn't a great idea. These panels aren't weatherproof, so if your sprayed solvent runs into the crack between the panel surface and the display bezel, there will be tragedy. Furthermore, Windex is a glass cleaner: a lot of your screens' outer layers aren't glass, or have some kind of delicate coating. Ammonia-based cleaners, for example, can microscopically abrade some plastic surfaces, causing your screen to become slightly foggy over time. And for your cleaning tool, paper towels aren't terrible, but they're also somewhat risky—screen coatings can be extremely delicate, and paper towels can sometimes be a little rough. Plus, they're prone to leaving streaks, no matter what liquid you're using.

So, what's the trick? Water. Water and a soft, lint-free (ideally microfiber, which is better at picking up greasy smudges) towel. To clean your panel, dampen your cloth and strain it out as best you can—you don't want any drippage here—then run it, folded, gently across your screen, repeating until the screen has been thoroughly covered and any sticky residue has been removed. (For larger displays, perform cleaning in sections, so as not to let the water dry or collect and run.) Now do the same with a dry cloth, applying slightly more pressure, to lift away the dirt and moisture. Repeat if there are still grease deposits. That's it! A few bucks for some soft cloths, a little bit of water, and your screen is as good as new.

And those specialty cleaning kits? They do work, for the most part, but they're not necessary.

TV and Game Controllers

By the time your TV is in need to a deep cleaning, your remote—or your videogame controller—is probably in even worse shape. The kind of dirt a remote gathers is an order of magnitude more disgusting (and more human) than your panel, so you're not just cleaning, you're disinfecting. Interestingly enough, the cleaning method isn't too far from the one above: A damp cloth, with some water. This time, though, you'll want to throw a little isopropyl alcohol in the mix—a 40/60 booze and water split works—to help disinfect the buttons, and remove the oily brown buildups you can get between buttons. Again, soft cloth is better than paper towels, this time it tends to be a bit better at reaching between buttons than stiff, thin paper. Use wooden toothpicks for reaching into cracks, but nothing harder.

These are unique in that they're shared gadgets. And shared gadgets are, almost without fail, fantastic vectors for germs. So what I'm saying is, clean them or die.

Cameras

Body: Cleaning your camera body is like cleaning almost any other gadget—a very slightly damp towel will do the trick. (Though be gentle around openings, since point-and-shoot camera guts lurk awfully close to the surface, and any intruding water can wreak serious havoc.)

Lenses: Lenses are dirt magnets, and if they're dirty, you simply don't get good pictures. They're also delicate and expensive, so you can't just reach in there with a paper towel and be done with it. Lens cleaning kits are available at every camera store, and include a light cleaning solution and microfiber cloth. These are safe bets, but don't spend more than $15 bucks on them. Lens pens also work, but they're a riskier proposition—there's such a limited cleaning surface on those things, and I always get the sense that after a few uses, the cleaning element has been sort of tainted.

Again, though, stay safe with this one: Buy a microfiber cloth, and simply rub the lens with a circular motion until all visible smudges are gone. Never apply too much pressure—any dust or dirt on the lens can get picked up in your cloth and scratch your lens—and fold/refold your cloth to ensure you're using a fresh surface at least once during a lens cleaning.

Two small notes on lenses: Don't forget the clean the rear glass on any DSLR lens. There's a lot less surface area there, and since it spends most of its time inside the camera or a locking lens cover it probably won't be as dirty, so this should take much effort. And if you can, treat each of your DSLR lenses to a UV filter. While this is called a filter, it only block light that humans can't naturally see, meaning that in most photos, the effect will be generally unnoticeable. (More on that here) Point is, you don't have much to lose by buying one of the dirt-cheap filters, and it will provide a layer of transparent protection from dirt and scratches over your lenses at all times. And since they're flat and thin, they're easier to clean than convex lenses.

UPDATE: I've gotten a couple of emails from photo pros about this, and I think it bears mentioning: Before rubbing your lenses, it's good practice to blast them with a little air. Air pumps (like the one mentioned in the following subsection) and canned air will do the job, as will, in a bind, your lungs. The thinking here is that you should remove any potentially abrasive particles from the lens before rubbing it, so as not to drag them around, causing permanent damage. —Thanks, Jody and Ned!

Sensors: Point-and-shoot and bridge camera users don't have to worry about this, but DSLR users, who provide a chance for dirty to enter their camera bodies every time they change a lens, may need to clean a sensor one day. It's not as scary as it sounds!

First of all, you'll never have to actually clean a sensor, since DSLR sensors all have some manner of filter, either IR or UV, built in. But still, the surface is delicate, so you'll want to be cautious. Most cameras include some kind of sensor-cleaning function in their software; since most sensor taint is comprised of a stray speck of dust or two, a quick, severe vibration will usually do the trick.

If that doesn't work, and your photos are showing persistent, faded, unmoving spots in every photo, it's time for phase II: air. For this, I defer to Ken Rockwell:

After 17,000 shots I finally got a speck on my D70. Remember I also change lenses a lot. The Shop Vac wasn't enough. This time I used an ear syringe (blower bulb) from the drug store which you can get here. I put the D70 on BULB and pounded the bulb with my fist to create a jarring blast of air. That worked.

Rockwell advises to use an ear syringe; I'd say go with a purpose-design lens blower, since they're still only about $10, and you'll get better results without running the risk of pulverizing your DSLR's guts while trying to get muscle enough airflow through a hard rubber earwax remover.

Beyond built-in sensor cleaning and a few blasts of air, there are plenty more methods for cleaning a sensor, but they're all risky to varying degrees. Unless you're supremely confident (and careful) it may be best to leave this one to the guys are your local camera shop, assuming you still have one. A ruined sensor, in most cases, is a ruined camera, so tread carefully.

Laptops

Screen grime is the most common cleaning problem with laptops, and with the display cleaning section of this guide, we've got that covered. That said, laptops collect filth in a variety of other ways, and they can get real microbial, real fast.

To clean a typical keyboard—that is, a non-chiclet design—you've got three steps to try. First, use a damp cloth with the aforementioned 40/60 alcohol/water mixture, turn off the laptop, and run it across the keys. Fold it a few times and use the edge to reach between the keys. You can use this same cloth to clean the rest of your laptop as well, excluding the screen, but including the touchpad. If that doesn't do the trick, and you can spot some dust or hair in between keys, it's time for some canned air. You can pick this stuff up at most big box electronics stores or online for $10 or less, and using it is as simple as tilting your laptop sideways, and blowing air in the cracks.

If this doesn't work, it's time to start popping off keys. Since you're disassembling a keyboard that really isn't meant to be taken apart, there's a definite inherent risk here, but the results are practically guaranteed to be good. Here's an extremely thorough guide, if you're game for it. To give you an idea of what this entails, there's a point in this tutorial at which all your laptop's keys are swirling in a cereal bowl full of soapy water. It's gruesome.

Another problem area for laptops is fans, air intake vents and heatsinks. These all stand in the pathway between outside air and your processor, which needs said air to keep cool. Any blockage can cause your laptop to run hot, your fans to run high, and consequently, your battery to run low. Disassembly instructions will vary from laptop to laptop, and typically will involve removing your entire keyboard. Once you've done this, though, removing the dust is a matter of blasting with air, scraping with a clean toothbrush or even just wiping with your finger. It's not about total cleanliness here, it's about clearing your computers' windpipe.

Another helpful trick: Those white, last-gen MacBooks have a disgusting tendency to accumulate a beige (then brown, then black) residue where users' palm touch the laptop. This discoloration is more of a stain than a buildup, so you can't fix it with water or alcohol. The fix? Acetone. Seriously, the best way to wipe that crap off is with nail polish remover.

Desktops

We've covered how to clean most of the external pieces of a laptop already: any plastic surface gets a moist wipe-down; keyboards get compressed air. That's it! Your desktop is sparking clean! This feels so good! Now slide of your desktop's side panel, and weep. If you've had your desktop for more than a few months, and particularly if you keep it in a carpeted room, it's probably an absolute horror show.

The first thing to do is, you guess it, pull out that microfiber cloth. Wipe down every surface that's finished, which is to say covered in rubber (wires) painted (the inside of the case, and the plastic shell of an internal optical drive, or the decorated exterior of a video card) or inert (the blades of a fan, or the exterior of your heatsink). You can slightly dampen the cloth to help pick up dust from the corners of the case, but your probably don't need to, and it's best to keep this a dry operation, beginning to end. Next, whop out that can-o-air, and have at it. Pay special attention to dust buildup areas, like the heatsinks on your processor and video card, and the fan inside your power supply. This will likely cause some dust to resettle elsewhere, so you may need to repeat your wipedown/blow process once more. Again—cleaning the inside of your tower is less about maintaining a spotless appearance than it is making sure dirt, dust and hair buildup won't negatively affect your computer's performance, so don't get too anal about it, cosmetically speaking.

Cellphones and Media Players

Cellphones, iPods and other media players are designed to be pocketed, so you can be a little rough on them during the cleaning process. A very slightly damp cloth or paper towel will remove whatever fingerprint or residue your shirt or jeans won't.

As much as these gadgets are intended to live in pockets, they have an irritatingly high number of places for dust to hide itself. Cellphones have keypads, or, increasingly, sets up buttons at the base of a touchscreen or on the sideof the handset, all of which give dirt a place to accumulate. The grilles over cellphones' mics and speakers is another refuge for sludge, and they're totally immune to simple wipedowns. For this, you've got to go one step further. Luckily, you've probably got all the supplies you need in your house already.

Wooden toothpicks and old toothbrushes help reach into cracks and crevices, like those around buttons or running around the perimeter of some display panels. (Samsung and HTC are particularly guilty of leaving spaces in places like that.)

Sometimes, as in the case of the tiny little mic/speaker grilles on some phones, you don't want to push dirt in, but rather pull it out. For those situations, lay a strip of scotch tape over the afflicted area, run your finger over it a few times, and pull it off. If that doesn't work, upgrade to duct tape—though you'll want to be a bit more gentle with that, since applying too much pressure can leave adhesive on your device, which is a pain to wipe off.

Resolution aka 720p vs. 1080i vs. 1080p
Resolution is pretty simple—it's the number of individual dots (pixels) that make up a display, arranged in a grid. However, when it comes to TVs, we tend talk about it in a slightly weird way, as lines of resolution (think of a FourSquare board), and we tend to do it in shorthand. So, for instance, what's considered "standard definition" is a resolution of 640 x 480, which refers to 640 vertical lines, and 480 horizontal lines. A 720p TV has 720 horizontal lines of resolution, and most typically, 1280 vertical ones. A 1080i or 1080p TV is 1920 x 1080. And the whole 1080i vs. 1080p thing—i stands for interlaced, where only every other line of resolution is displayed, while p is for progressive scan, where the whole picture's displayed at once. Really, since even the cheapest sets are progressive now, you don't have to worry about it.

An important thing to consider, however, is the Lechner Distance, or the distance at which your eye can actually process all of the detail in a 1080i/p resolution image. While you should consult the chart, basically, if you're sitting further back than 7 feet from a 52-inch TV, your eyeballs can't actually resolve the difference between 720p and 1080p, so you might as well save the cash.

Motion Resolution
A somewhat trickier spec that some TV experts swear by, it refers to how well a set's resolution holds up when stuff's actually moving on the screen, like a baseball player running down a field. Plasmas tend to have better native motion resolution than LCD, but LCD has been fixing this problem. (See "hertz," below.)

Viewing Angle
Basically, it's how far to each side of the TV you can be and still see the picture, measured in an angle that is, naturally, less than 180º. Again, traditionally this was more of an LCD problem than a plasma one, but all TV technologies have had some issues in the past, and the worst offenders used to be DLP and other microdisplays.

To see viewing angle at work, start where the picture on a TV looks best, and move to one side—now note where the picture starts looking weird, with the colors changing, washing out and getting hard to see. Nicer sets reach nearly 180º, so plenty of people can take part in the HD glory.

Hertz, or What 120Hz and 240Hz Mean
Hertz is basically just the number of times the image onscreen refreshes a second. Because of broadcast standards, TVs in the US need to be 60Hz, meaning they refresh the image onscreen 60 times a second. (In Europe, the standard is 50Hz.) Video sources are generally 30 or 60 frames per second, because of this, and a regular video camera shoots at 60fps a second. So typically, 60Hz sets are the norm.

Lately, though you have 120Hz, and even 240Hz sets, all of them LCDs. They do this to increase motion resolution—see above. A 120Hz TV refreshes 120 times a second, and it comes up with those extra frames by making them up—either duping the frames that are there and putting black spaces in between, or by splicing in intermediary frames that are basically realtime morphs of the two frames they come between. Stuff looks really smooth—sometimes too smooth, true—but the point's to fight LCD's motion blur disadvantage against plasma.

240Hz is another ball of sticky still, promising less motion blur, but with a tradeoff. but there are two different ways to achieve it. One way's kind of cheating, in that it's a 120Hz that uses a flashing backlight to simulate 240 frames a second. The other, more "legit" 240Hz is genuinely faster, with images staying up on the screen for just 4ms before moving to the next. There's no real way to tell which kind of 240Hz a TV uses (though a "scanning backlight" is a tip off it's not the "real" 240Hz). There is a law of diminishing returns in reducing motion blur as you climb past 240Hz, but for some serious AV nerds, like Home Entertainment's Geoff Morrison, it does make LCD TVs more watchable.

Plasma TV brands sometimes boast "600Hz," but that's mostly to show off to LCD shoppers that these kinds of motion-blur refresh problems are really specific to LCD. It's not so much a spec as a declaration of the tech's superiority in this department.

To make things just a tad weirder for you, films have been shot since ancient times at 24 frames per second, so many TVs have a 24P mode, meaning the screen refreshes 24 frames per second, or in multiples thereof. (Any mathmagician can tell you that both 120 and 240 are divisible by 24.)

Plasma
The basic way plasmas work is that there's a party of noble gases trapped between two glass panels that are zapped and light up all pretty. More practically, what plasmas offer over LCDs is superior color (often), better motion (typically) and deeper blacks (always and forever, with a couple of exceptions). The tradeoff is that they're more power hungry, and generally heavier.

The life-or-death questions people have about plasmas are almost mythical now: Burn-in, where an image is permanently etched into the panel after being left up on screen too long isn't really problem anymore (unless you're sadistic to your TV). The "Denver problem," where high altitudes affect sets, is less of an issue, but it exists: If you live at 6,000 feet or higher, you should read this summary by our friend David Katzmaier at CNet. Panel half-life is a very long time, now, about the same as LCD's backlight (which, of course, could be replaced, but we're talking like 10 year out). When it comes to the cheapest TVs, 720p plasmas are hands-down the safest bet for best picture quality.

LCD
The people's HDTV technology, LCD, stands for liquid crystal display. The liquid crystal part is a gel that sits in front of a backlight, which is divided up into pixels. There are two main kinds of backlights used, CCFL (pictured, via Home Theater Mag) which are like the lights in your high school cafeteria), and LED, which we talk a bit more about below. There are two major kinds of LCD displays. There's the traditional twisted nematic kind (TNT), which is cheaper and known for faster response times, and then there's in-panel switching (IPS), which is more expensive and usually slower response times, buuut it's got a wider viewing angle and better colors.

On a broader level, the stuff to consider with LCD when it comes to actually buying a TV, is that, on the cheap side, LCDs tend to have worse motion and less excellent contrast ratios than plasma. You step up a bit, and it starts to even out. Especially if you pony up for the best of the best LCD TVs, typically lit up by LEDs. LCDs in general are way more eco-friendly, slimmer, and—because of their backlights—better to watch in environments where you're gonna have a ton of light spilling in.

DLP
DLP is a rear-projection technology made by Texas Instruments that creates the image onscreen using a whole bunch of tiny mirrors that reflect light through a lens. The big thing about DLP sets is that they're, um, big and for cheap—a 65-inch DLP set is just $1500. But you're probably not gonna be mounting this sucker either.

DLP is the last survivor of the "microdisplay" projection TVs, that also included LCD and LCOS techologies. They are great on contrast, but they got killed by flat panel because you can't make them an inch thick.

Laser TVs
Mitsubishi's LaserVue TV is a microdisplay projection set (with a DLP chip) that is lit up by lasers instead of just focused light. Thanks to this, it delivers some of the most amazing colors and deepest blacks possible, as good as plasma sets, but at a ridiculously low power consumption. Sadly, you'll probably never buy one, and not just because it's $5000 for a 65-inch set.

Contrast Ratio
So, technically, contrast ratio is just the ratio between the brightest and darkest images a display is capable of showing, which sounds like an objective enough specification. But like many specifications, this one has been turned into a marketing tool, and subverted to a point where it is not helpful. In the lab, there are several kinds of contrast ratios: Static, which is the ratio between the brightest and darkest a screen can display simultaneously, and dynamic, which is the darkest and lightest a screen can ever be at any given time. Sadly, it's this latter figure that most TV makers brazenly display on their boxes, to the tune of ridiculous numbers like 1,000,000:1 (or more). It's utterly meaningless, and you're better off ignoring it.

OLED
It's the beautiful future of television, but vastly too expensive for anyone but CEOs to own right now because OLED displays are really hard (read: expensive) to make at large sizes. "OLED" stands for organic light-emitting diode, and what's special is that the individual pixels light up by themselves, like plasma, but can be laid out on a single sheet of glass (or plastic), like LCD, so they get the best of both: They're super thin, they don't need a backlight, they have higher contrast, and they're energy efficient too. Also, they may one day—soon—be bendy!

LED TVs or LED Backlighting
While a standard LCD set is lit up by a cold-cathode fluorescent lamp (think dreary lighting from high school), the best LCD sets use LEDs (light-emitting diodes). They can be configured a few different ways: Edge-lit, where the LEDs are arranged in strips along the sides of the TV, and allow it to be super-thin; and backlit, where a grid array of hundreds of LEDs sits behind the screen and, with local dimming, where clusters of lights turn on and off individually, offers the best LCD money can buy. Three of the five best TVs you can buy are LED-lit, if that tells you anything. And no, they're not cheap.

3D
If you thought you heard a metric shitton about 3D this year, just wait for 2010. We have a giant primer on 3D tech right here, but there's just a couple you really need to know. Polarized 3D glasses are the cheap 3D for the masses—i.e., IMAX—where two synced projectors throw out two different images are slightly different polarizations that can only be seen by one eye at a time, making your brain see stuff in 3D without that annoying red/blue thing.

And while we kinda made fun of them, shutter glasses are actually the way 3D is moving in nicer implementations, from Panasonic and Nvidia, among others. Essentially, the glasses are battery powered, and shutters blink rapidly over each eye timed to the refresh rate of the display, so each eye sees a slightly different image as the shutter opens. It works better on plasma than LCD (even 120Hz models), in our experience.

Anti-Glare vs. Anti-Reflective
Anti-glare and anti-reflective displays, surprisingly are not the same thing. Anti-glare displays often try to diffuse light coming at a display with a treated or textured surface, almost like a "matte" finish. It's about cutting back external light hitting the display, but the tradeoff is that the picture coming through may not be as clear. Anti-reflective deals with light that comes from the display itself, as well as external light, and handles this with special coatings or films that minimize reflections from all angles to make the picture clearer. (Just think about eyeglasses, with that greenish coating. Same idea.)

HDMI
Honestly, the only thing you really need to know about but the High-Definition Multimedia Interface—you know, HDMI—is that the cables in most retail stores cost waaaaaay too much. If you pay anything over $10 for an HDMI cable, you are getting suckered. Order cheaper cables from Monoprice.com and other retailers—they do just fine as long as you're not installing them inside your walls. (If you're doing that, you should pick something heavily coated and insulated, and built to last a few generations of TV.) Oh, and there's a new version coming out—HDMI 1.4—that supports higher resolutions and internet. Not only will that require brand new HDMI cables, it will require new TVs and new content too, so it's a ways off.

When the police arrived, the man, identified as Jerome Charles Eberle, ran through the store while swinging the hammer at the officers. Eventually, they brought him down with a Taser. Eberle claims that he only remembers parts of the incident inside Target, and he is currently undergoing a mental health evaluation.

According to the list, if you are looking for a 1080p HDTV over 40-inches, you definitely have some options: like a 42-inch Panasonic VIERA plasma for $712 (with coupon code and price protection adjustment, see list for details) and a 50-inch Panasonic plasma for $1096 (Buy.com, after the jump). Not only the list save you time, it will help you avoid wasting money on a bad deal. In fact, HD Guru confided in us that "most of the other so called sales are BS." That's not really surprising when you consider that the same could be said for Black Friday deals. [HD Guru]

The extra 3D hardware inside the TVs isn't likely to have a big price premium, but the glasses required to see 3D content could be sold separately for up to $200. The idea is to keep TV prices down, and let users grab the glasses if or when they want.

The march to 3D isn't just coming from Sony. Panasonic, JVC, Samsung, and Mitsubishi have also shown 3D TV models, and Panasonic's first wave of 3D Plasmas are on track to arrive next year. Fingers crossed we get a hands-on preview at the Consumer Electronics Show in January. [PC World]

Pixel Qi's last announced manufacturing date—residue of which still graces their website—was "the second half of 2009." In big, bold type, they've updated the claim: "We are starting mass production of this screen in December 2009," is proudly emblazoned on Pixel Qi's worryingly retro website, while "We totally totally promise this time," a comforting, if slightly desperate adjunct, is not. But this is:

We have begun design of a sub-10 watt HDTV that can be used in hundreds of millions of households that don't have steady, if any, access to electrical power. The typical HDTV uses more than 100 Watts and often draws several hundred watts. We are working on a way to massively lower the power consumption, and significantly lower the price with a target price of $100. Thus this HDTV can run off of battery that can be charged up when the power is on, or charged with a small solar panel, crank, or so forth.

I'm sure there are about a million different applications for a low-power screen tech that displays full-motion color, static e-ink and works in the sunlight, but don't get ahead of yourselves: we haven't seen a single non-prototype device yet. Throw us a bone, guys! And by bone, I mean the name of any hardware partner who's willing to make a product with this screen tech once it starts shipping. [Pixel Qi via Blogeee via Slashgear]

To be clear, we're only looking sets that are at least 46 inches—go big or go home. And though there are some nice 720p plasmas out there for amazing prices, the majority of TVs we're concerned with are 1080p—it's the standard now, even in cheap HDTVs, and probably the only resolution you'll see next year.

We focus on LCDs quite a bit here, not because we prefer them, but because there are key enhancements that can be put in LCD technology to make them look better. With plasma, the problems—energy consumption, weight, thickness—are more of an evolutionary, year-to-year thing. A cheaper plasma often is one that's just using older technology.

Also, we're using Amazon as our pricing base line, since it's on average a good standard for low but legitimate street prices, and we use Samsung examples a lot because they have a ton of different models on the market, so it was easier to isolate individual features, and to gauge subtle differences in pricing.

Size Matters

The first, and most obvious thing that'll cost you is more screen real estate. There's not an absolute inches to dollars ratio, but generally speaking, the first step up is the cheapest, and somewhere in the middle, there's a sweet spot, after which you basically lose money by upgrading. The funny thing is, each maker seems to have a different idea of where the sweet spot is, which you could play to your advantage:

Take for instance, Panasonic's plasma G10 series. It's $200 to go from the 42-inch model to 50, and then $400 to go up to 54. So the sweet spot is at 50 inches. Similar thing happening with Vizio's XVT line: Going from 42 to 47 inches is just $250, though going up to 55 from 47 costs about a a grand. Hence 47 inches makes the most dollar-per-inch sense if you like that TV.

With Sony and Samsung, though, it pays to keep going up. In Sony's top-of-the-line Bravia XBR9 series, the hop from 40 to 46 is $360, but going from 46 to 52 is just $250. Samsung's LED-backlit TV costs $350 to go from 40 to 46, and just $500 to go from there to 55 inches. (There's a limit, of course, Samsung's 65-inch LN65B650 doesn't have many of the frills discussed below, but still lists for $6000.)

The real lesson here: Don't think of size as a foregone conclusion. When you've narrowed down your options using all the criteria, go back and check the sizes and relative prices. There may be a surprise, hopefully good but possibly bad.

Vroom, Vroom

Everything after size you can roughly sweep everything you'd pay more for into the category of performance. The grand trick of buying TVs though, according to our friend Gary Merson of HD Guru, is that "the TV industry is setup like the car industry." Just like buying a Corvette to battle your mid-life crisis because it vrooms real good, when you pay extra money for extra horsepower, you're also going to get leather bucket seats and the in-dash GPS. It's hard to buy a stripped-down car that just delivers better performance, and the same goes when you're trying to scrimp on a TV without compromising picture. In the case of TVs, a higher performer might come with a million HDMI jacks or integrated Wi-Fi and video on demand, and you never know exactly what you're paying for.

Fortunately, we can break performance into a two major categories so it's slightly easier to interpret those price differentials: Backlight (for LCDs) and panel quality.

Fancy Backlighting

The single most expensive upgrade for LCD TVs right now is LED backlighting. As we explain here, there are a bunch of advantages to LED over conventional CCFL backlighting for LCD TVs. Which particular advantages you pick up depends on the kind of LED backlighting in the set. While both offer instant on and power savings, edge-lit models mainly deliver serious thinness, while backlit sets can offer local dimming, which delivers noticeably better black levels and contrast.

How much will it cost you? Well, comparing two Samsung sets with fairly equivalent panels, the price difference is about $500. The CCFL-backlit LN46B650 is $1360, while the UN46B6000 is $1850. Because it's got LED edge lighting, the B6000 is only 1.2 inches thick, compared to the B650's 3.1 inches. When you step up and compare Samsung's edge-lit to back-lit, the difference isn't as great: A 46-inch 8000 series edge-lit model goes for $2300, while the 8500 series with local-dimming is $2600. (If you're already paying for LED technology, you definitely want to step up.)

So yes, backlit LED sets with local dimming tend to cost more. Sony's year-old Bravia XBR8 uses tri-color LEDs to improve color accuracy over the most LED sets, which use white ones. Though its production is discontinued, it's still nearly $2200 at 46 inches. However, Toshiba consistently delivers cheaper sets than most of its fellow "name" brands, and their 46-inch LED backlit set with local dimming is just $1700.

Panels and Oh, It Hertz

The panel is the other major thing that determines how good an HDTV actually is, and it applies to both LCDs and plasmas. Typically, as you move up in price, you get a better panel. Cheaper sets generally use older panels with previous-generation tech that Merson says have a poorer viewing angle, so there's a smaller area you can actually stare at on your TV to get a good picture. The problem is that no TV manufacturer actually declares its panel attributes on the box, so you're often on your own to figure it out. The best way is to go to the store and check out the viewing angles.

Hertz, for the uninitiated, is simply the number of times per second that LCD TVs refresh their picture. (Plasma isn't part of this discussion because phosphor pixels work differently than liquid crystal ones, and plasma's "refresh rate" would be way higher—to the point of irrelevance.) A 60Hz LCD refreshes the picture 60 times a second, 120Hz is 120 times a second, and so on, up to 240Hz in the top-priced LCD sets. A higher refresh rate is supposed to increase the ability to see fast-moving video at its highest intended resolution, and works well in theory, though there are issues with 240Hz execution. At this point, a minimum of 120Hz is a given on all premium LCDs, says Merson. There isn't one LED-backlit set that doesn't have it.

Here's how the refresh-rate step-ups look: The 46-inch Samsung B550 is a standard 1080p CCFL-backlit set for $1020. Moving up to the same size B650 for $1360—$300 more—gets you 120Hz (plus a higher contrast ratio). Going up again, to the B750 for $1630, another $300, you get 240Hz, and again even better contrast ratio. That's about the top of Samsung's CCFL-backlit line.

You can see the same thing with their LED sets: The 46-inch B6000 is a 120Hz LED edge-lit set for $1850. The 46-inch LED edgel-lit B8000 goes to 240Hz, and it costs $2300, about $450 more.

What About Plasma?

As we mentioned, plasmas are a little less complicated, since there's nothing like refresh rates to deal with. On the other hand, the situation may be more obtuse, since you don't always know what the real differences are. Merson says there are a few basic levels of plasma performance. On Black Friday, Walmart is selling a 50-inch plasma for $598 if you don't mind the fact that it's 720p (and branded Sanyo, which is probably Panasonic-based but who knows?). Stepping up to the 50" 1080p plasmas will generally cost $300 to $400 more.

There are more issues, however. Panasonic has a new panel called NeoPDP that's more energy efficient, but it's sometimes hard to tell which models have it and which don't. (Hint: Look for the Energy Star sticker.) Finally, you have THX-certified panels that offer nearly perfect calibration right out of the box. Beyond that, contrast ratios do tend to get better over time, but it's relative: At the low end of the HDTV price spectrum, plasma sets have generally delivered better picture than LCD anyway.

Frills and Other Stuff

The funny thing about TVs nowadays is that there's more to them than the screen. Like inputs. Until recently, one thing you got more of by paying more money were more holes to stick things into. That's not really the case once you get up into 46-inch sets—you're gonna get 4 HDMI slots in a set that big no matter what. But, there are other things nowadays. Like video services that come in through other holes, or maybe without wires at all.

An example, to use our old friends at Samsung: The B6000 looks a lot like the B7000, but with the B7000, for $180 more, you get online video services via Yahoo's widget engine, like YouTube.

Or, let's look at the upcoming crop of LED TVs that aren't even out yet, or are in limited distribution for now. LG's 55LHX and Sony's Bravia XBR10 both have wireless HDMI and 240Hz, but with Bravia Internet Widgets and Slacker radio, the Bravia is $5000, $200 more than 55LHX. Wireless HDMI itself is a pretty pricey feature. Same Sony, compared to Samsung's 8500. The 8500 has built-in video services, but no wireless HDMI, and it's $500 cheaper, at $4500. Oh, and did I mention that the Sony is even 3 inches smaller than the Samsung and LG?

Wireless is still in the gimmick phase, but next year, we assume we'll be able to track its price premium as well as we can track size, refresh rate, backlighting and other factors today, $300 to $400 at a time. How do you get from $600 to a $6000? You just add, add some more, and then keep adding.

The HDTVs included models from the top-tier brands of (alphabetically) LG, Samsung, Sharp and Sony - from the mid-line to top-of-the-line models. All of the units were from the 2008 model year. Differences between the 2008 and 2009 models are primarily in their marketing hype. For this article we had three flagship top-of-the line LCD models from Samsung (LN-T5281F), Sharp (LC-52D92U) and Sony (KDL-52XBR4). By studying the top-of-the-line models from the market leaders we were assured of examining the state-of-the-art for each display technology and each manufacturer. The consumer mid-line models included LG (42LG50), Samsung (LN40A550P3F), and Sony (KDL-40V3000). The remaining two LCD units were consumer HDTVs but not commercially available models.

The top-of-the-line Sony XBR and Sharp units had 120 Hz screen refresh, the top-of-the-line Samsung had strobed LED backlighting, and all of the other units had standard 60 Hz screen refresh. The goal was to determine the degree to which this varied advanced technology affected visible motion blur.

DisplayMate analyzed the blur using moving test patterns, moving photographs and live video (a Nikon D90 DSLR with a shutter speed of 1/160th a second was used for the photography) and found that no actual motion blur detectable in any of the live video content—although there were incidents that were passed off as defects in the source video or temporary optical illusions.

After extensive side-by-side objective testing with moving test patterns, moving photographs and live video we found that there was no visually detectable difference in motion blur performance for current mid to top-of-the-line LCD HDTVs, regardless of their Response Time, 60 or 120 Hz refresh rates, strobed LED backlighting, or motion enhancement processing. While there was considerable motion blur in the moving test patterns, motion blur was simply not visually detectable in real live video content during our extensive side-by-side testing. With only a handful of minor exceptions, whenever blur was seen in live video we always found it to be in the source content or a temporary visual illusion that disappeared when the segments in question were reviewed. This is undoubtedly due to the way the brain processes and extracts essential information from dynamic and complex moving images.

In other words, DisplayMate thinks you are probably seeing things. Don't be fooled by manufacturers charging extra for fancy motion blur technologies or claims of exceptional response times. If you purchased a mid to top tier model you shouldn't have anything to worry about. Of course, this test doesn't remotely cover all of the LCD brands out there, so I have to ask—based on your experience, do you believe that LCD makers have finally tamed the motion blur beast?

Well, at least not in Roaming Navigation view.

Instead, the shows are grouped by relationship—common threads like genre, title, and hours of original play. The more overlapping qualities, the closer the thumbnails are sorted to one another.

At first, the idea of sorting by title similarity sounds a bit ridiculous, but for those who watch CSI, CSI:Miami, CSI:NY, CSI:Indianapolis, and CSI:Millersburg, OH, it's probably pretty handy—especially if they watch Law & Order, too. [Tech-On]

Samsung's plasmas are pretty quality (I've got one of their 63 inchers), so you should take a long hard look at your bank account and see if you can afford this. Seriously, free shipping too. And that rotating stand is very handy. [Newegg]

Two groups of 30 people watched the same video clip, individually, on the same television. Half were told to expect a better experience thanks to HD technology, an impression backed up by posters, flyers and an extra-thick cable connected to the screen. The other half were told to expect a normal DVD signal.

Of course, the group expecting HD reported a far better viewing experience, saying it was clearer and crisper than standard def. It wasn't, of course. This basically explains why Monster Cable is still in business. [New Scientist via Consumerist]

Yes, this $76,583, 56-inch set sports a resolution of 3840x2160, which means you can cram four full-res HD feeds in there at one time. You know, for watching four football games at once, or four movies at once. Samsung announced a similar, larger set a couple years ago, but as far as we know it never actually became a real product. This thing is all real.

Sure, this thing isn't meant for normal consumers, as the price makes it clear. But that doesn't mean you can't get one if you have the scratch. Come on, go for it. It's only $76,000. [AV Watch via Engadget]

One look at this television and it's no surprise to learn that its designer was also responsible for the distinctive Citroen DS which was first produced in 1955. It features a 19-inch screen with white mask, in a tapered-hood case in deep purple with a gold trim. The controls and speaker sit in the rectangular box below and the screen can be turned independently through 150-degrees as well as angled vertically.

The set is also "dual standard", with capability to show 441 lines (which became the standard from 1952) along with a high definition facility of 819 lines, meaning it is high-definition even by today's standards. This system began in France in 1949 but never really got off the ground. Bennett-Levy speculates that Teleavia may have been trying to "future-proof" the P111 in case the French government decided to resurrect the service.

Given the wildly varying conditions of the show floor—and the frankly crappy source video, lighting and background LG picked for its demo TV—we can't really judge which TV actually has the best picture quality right now, but the facts do tell us something:
• Samsung and LG both use local dimming on their 55 inchers, while Sony's 52-inch TV is edge-lit
• Sony and LG have expensive built-in wireless HDMI for 1080p streaming from a paired media box
• Sony and Samung have the best "other" features, like great streaming video services
• Samsung's the cheapest, at $4500 for its 55-inch set, probably because it lacks wireless
• Sony's is the most expensive, even though it's the smallest, and lacks full-array LED backlighting, like its champion precursor, the XBR8

In person, the XBR10 is gorgeous, really pulling off the floating TV look, and the Samsung 8500 sets are slick and slim. LG's 55LHX is comparatively drab and physically more clunky, as you can see in our Sizemodo:

Red = 55" LG; Purple = 52" Sony; Yellow = 55" Samsung

All in all, there's no clear winner, and there are lots and lots of trade-offs. If you really want to blow five grand on a TV, you're going to have a tough decision for now, at least until we get 'em side by side. [More CEDIA '09 coverage]

(Okay, in fairness, it kind of is.) [XBR10@Giz]

Like the XBR10, it streams 1080p from a wireless source, plays 24p content and has 240Hz tech that you can't see. But it's 55 inches, while the biggest XBR10 is 52, and it's got THX display certification (as, um, useful as that is). What the Sony has over it is the excellent XMB media interface and Bravia Internet Video (with Amazon On Demand, Netflix and other services), though you could use the difference you pocket with the LG to pick up the Vudu-streaming BD390 Blu-ray player that has built-in Wi-Fi.

In other words, until we see how good the picture on both of these are, it's a tossup—though the best LED-backlit TVs are locally dimmed, so Sony's got a tough fight.

The lesser LH85 isn't LED-backlit, but it's got wireless HDMI too and is an also pricey $3200 and $2400 for 55-inch and 47-inch sets.

LG ELECTRONICS BROADENS HOME ENTERTAINMENT OPTIONS

WITH TWO NEW WIRELESS HDTV SERIES

Wireless LCD HDTVs Offer Flexible and Convenient Custom Installation Options

ATLANTA, Sept. 10, 2009 – Offering diverse integration options for custom installers, LG Electronics is highlighting its first-ever series of wireless LCD HDTVs, including an LED model, this week at the Custom Electronic Design & Installation Association (CEDIA) EXPO 2009 (Booth #2623).

Whether it's design, technology or screen size, LG's wireless HDTVs have something for everyone, according to Peter Reiner, senior vice president, marketing, LG Electronics USA, Inc. LG's 55-inch class* Slim Wireless LED-Backlight HDTV (model 55LHX) combines advanced technology with cutting-edge style for a TV that blends beautifully into any home environment. For those seeking a variety of design options, LG's LH85 series of wireless LCD HDTVs will be available in 47- and 55-inch class* sizes.

"As custom installers look to create a truly unique space, the wireless capability found in the 55LHX and LH85 models allow the freedom to place the HDTV anywhere in the room," said Reiner. "With wireless HDTVs, LG continues to expand home entertainment design and placement options to meet consumers' ever evolving needs."

Entertainment Freedom

Both 55LHX and LH85 wireless models allow installers the freedom to place the HDTV virtually anywhere in the room – without messy wires. To achieve this wireless experience, LG uses a supplied media box to transmit an uncompressed Full HD 1080p signal with virtually no interference or delay directly to the TV. The HDTVs can receive a wireless signal up to 30 feet away, allowing consumers to hook all content sources (such as a cable or satellite box, Blu-ray disc player, game console and home theater systems) into one box.

Enhanced Picture Quality

The 55-inch LHX model features superior picture quality with an elegant ultra-slim design – less than one-inch thick at its thinnest point. This unit has attained THX Display Certification. This certification ensures that the 55LHX delivers exceptional images, bringing a more immersive and enjoyable movie, broadcast and video game experience to consumers' living room. Since THX certification begins during the initial product design phase, every product detail is meticulously mapped to THX standards and tested in laboratory and home theater environments to ensure quality, usability and compatibility.

By presenting HD and standard-definition content at the maximum resolution with the correct color and luminance level, the LHX provides consumers a crisper, clearer image. To achieve this, LG uses a full-array LED backlighting system with local dimming technology, for precise picture control resulting in deeper blacks, wide color gamut and an incredible 5,000,000:1 dynamic contrast ratio. This model also incorporates TruMotion 240Hz technology for smooth motion during fast-action scenes.

LG's LH85 series delivers an 80,000:1 contrast ratio for deeper blacks and greater picture detail. Additionally, the LH85 series features LG's 24p Real Cinema technology that allows consumers to enjoy a true cinematic experience at home, the way the movie was intended to be seen. For those that want more from their HDTV, the LH85 also includes USB 2.0 functionality allowing easy access to MP3 files and viewing of JPEG photos for a more enjoyable TV viewing experience.

ISFccc Calibration Options

Those seeking advanced calibration based on their own home theater environment, will appreciate LG's ISFccc option on both the 55LHX and LH85 series. The professional ISF calibration helps to deliver picture quality, representing what filmmakers intended viewers to see.

Using the LG Expert Mode, an ISF-certified calibration technician will use professional equipment to calibrate the HDTV using ISF parameters based upon individual home theater environments and ambient lighting. Once calibrated to the optimal setting, the calibrations are saved as ISF "Day" and ISF "Night" modes. With ISFccc, LG offers a superior 10-point calibration. This provides an extra level of precision for gray scale calibration resulting in a more uniform picture.

Energy Savings

With Intelligent Sensor, both wireless models automatically optimize the picture to the lighting conditions in the room for a personalized and more enjoyable viewing experience; and potential energy savings. Both the LHX and LH85 series are Energy Star 3.0 compliant, and with LG's "Smart Energy Saving" package, which consists of features such as backlight control options and video mute, LG further paves the way toward greater energy savings, while also allowing consumers to customize their viewing experience.

The 55LHX will be available soon at a manufacturer's suggested retail price of $4,799 and the LH85 series will be available later this Fall in 55- and 47-inch class* screen sizes with MSRPs of $3,199 and $2,399, respectively.

LG ELECTRONICS BREAKS BARRIERS IN HOME ENTERTAINMENT

WITH SEAMLESS PANEL LCD HDTVs, LED BY STUNNING NEW LED MODELS

Sleek SL Series Models Couple Advanced Display Technology, Single-Panel Design

ATLANTA, Sept. 9, 2009 – Breaking barriers in home entertainment, LG Electronics today introduced a "Full HD" LED LCD HDTV – that looks almost as thin as the single sheet of glass it resembles.

Introduced for the U.S. market here this week at the Custom Electronic Design and Installation Association (CEDIA) EXPO 2009 (Booth #2623), the new 47- and 42-inch class* SL90 series HDTVs feature LED lighting and other display technologies developed by LG Electronics.

"LG continues to break barriers in design and technology with its stylish high-definition televisions, like our SL80 and 90 series," said Peter Reiner, senior vice president, marketing, LG Electronics USA, Inc. "These new ultra-slim series of LCD HDTVs position LG at the forefront of providing a new entertainment experience to consumers – one that focuses as much on design as it does on creating a more immersive home entertainment experience."

Unlike conventional LCD TVs, where the panel is recessed slightly within a thick plastic frame, LG's new series of LCD HDTVs use a single-layer design and narrow bezel to create these stunning sets, designed to maximize the viewing experience as well as enhancing the home interior.

LG uses a special film lamination technology for better color tuning, gradation and reduction of glare – all in a sleek, minimalist package. The lamination process completes the flat surface, virtually eliminating the visible line between the screen and the bezel when the set is turned off.

LG's latest masterpiece, the SL90 series, sports a depth of just 1.15 inches, making it a beautiful window into a new world of home entertainment, according to Reiner. "Inside its glossy enclosure, LG's SL90 hides technology that produces a great picture and makes every program and movie even more entertaining," he said.

For example, the LED LCD screen helps produce an extremely high dynamic contrast ratio of 3,000,000:1 for truer blacks and finer gradations between grays. An additional benefit of the film lamination process is to provide anti-glare properties to the screen, reducing distracting reflections and to help ensure that everyone in the room has a cinema-quality experience.

The SL90 series also incorporates advanced display and calibration options, providing home theater enthusiasts and custom installers a sleek new approach to home entertainment. With TruMotion 120Hz technology, the SL90 reduces motion blur and creates more natural looking images for a better viewing experience. By responding quickly to color changes, LG's 120Hz technology provides superior picture quality at different viewing angles.

The SL90 series will be available later this Fall in 47- and 42-inch class* screen sizes at manufacturer's suggested retail prices of $2,599 and $2,099 respectively.

Expansive Entertainment Options

Also on display at CEDIA Expo this week is LG's SL80 series of LCD HDTVs, which shares a similar stunning single-layer design with the SL90, using a sleek edge-to-edge panel of glass over a slim bezel. This design makes the screen and bezel appear to blend seamlessly together.

"The SL80, with its slim style boasts a depth of just a mere 1.8 inches. The combination of this unique design with slim depth makes the screen appear larger and helps draw viewers in, for a more engaging viewing experience," Reiner explained.

The SL80 boasts TruMotion 240Hz technology to improve motion picture response time so consumers experience a smoother, more natural picture during fast-action scenes. Additionally, LG's anti-glare filter on both the SL80 and SL90 reduces glare to provide a more pleasant viewing experience even in brightly-lit rooms.

For a complete cinematic home experience, the SL80 has a dynamic contrast ratio of 150,000:1 for amazing clarity and color detail. The SL80 series utilizes slim CCFL technology to achieve its dramatically thin profile. Delivering a compelling visual experience, the SL80 series is less than 1.8 inches thick at its slimmest point.

The SL80 series is available now in 42-, 47-, and 55-inch class screen sizes* at MSRPs of $1,599, $1,899 and $2,799 respectively.

Advanced Calibration Options

For easy, self-calibration, the SL80 and SL90 both include LG's Picture Wizard technology. Picture Wizard provides consumers with on-screen reference points for key picture quality elements, such as black level, color, tint, sharpness and backlight levels. Now, consumers have the ability to calibrate their LG HDTV with an easy-to-use calibration process that takes the guesswork out of picture adjustments and eliminates the need to purchase separate calibration tools.

For consumers looking for advanced calibration, the SL series offers ISFccc calibration options to deliver superior picture quality to more closely represent what filmmakers intended viewers to see. Using the LG Expert Mode, an ISF-certified technician professionally calibrates the HDTV using ISF parameters based upon individual home theater environments and ambient lighting.

Once calibrated to the optimal setting, the calibrations are saved as ISF "Day" and ISF "Night" modes. With ISFccc, LG offers a superior 10-point white balance calibration capability, providing an extra level of precision for gray scale calibration for a more uniform picture.

Smart Energy Savings

As with all of LG's 2009 HDTVs, the SL90 and SL80 models feature Smart Energy Savings technology. These new sets meet the newest Energy Star® 3.0 ratings and come equipped with Intelligent Sensor, which senses the ambient light in the room and adjusts color and brightness accordingly and can also save energy. Additionally, a mechanical on/off switch eliminates standby power consumption completely, if desired.

While many TV makers are using polarized glasses in their 3D concepts, Sony's plans involve high-definition active shutter glasses that alternate the image for the left and right eye. Hopefully they won't make me cross-eyed like my old 3DFX Voodoo shutters did. [Sony]

This leak is all according to an unnamed source, so don't get too worked up, but supposedly Sony is set to announce the product at next week's IFA in Berlin. Panasonic has already committed to work on 3D TVs, but Sony could still be the first to get a product out the door. We'll have to wait until next week to find out if there's any truth to the rumor. [Wall Street Journal]

The design is both clever and functional, with the display's ports tucked behind the monitor in some sort of cross between a folded piece of paper and a photo frame. In turn, the necessarily hardware becomes its own stand, and the display can tilt, too (not that the viewing angle on most OLEDs is necessarily lacking).

The 15-incher will officially debut at the IFA 2009 show in Berlin, LG execs told Reuters, after which it will sell first in Korea before making its way overseas sometime after November.

And better still, at least for OLED fans, is word that LG is also preparing a 40-inch OLED product in the "not so distant future." We probably don't have to tell you that this "product" will undoubtedly be "expensive." [Reuters]

A whopping 33 HDTV models are on sale in the August 30th circular, including $1100 off several high-end Samsung LCDs. There are some nice Blu-Ray and stereo packages as well, sometimes up to $1500 off the regular price.

Apparently the start of football season is also the start of the big-screen buying season, although we wonder what Best Buy'll have to cut come Black Friday. Still, if you're in the market for a giant TV, next week might be the time to make the plunge. [HDGuru]

I only had it set up in my living room for a short while. A little HBO, some movies, not much gaming at all. But it would have been long enough to pick apart a TV by just watching it. And during that time Sony's picture defied any major complaints. Standard definition TV looked colorful, clear and without too many artifacts, reminiscent of how good it did on ye old standard def CRTs, before flat panels started hamfisting the upscaling. On the high end, High definition content from a Blu-ray disc felt like pricks from hypodermic needles, 1920 x 1080 of them, filled with a solution of video joy suspended in photons, as well as some unknown meds that made my chest tighten and my eyes unable to blink. It was by far the best LCD I'd ever seen, and as David Katzmeier from CNet said when he reviewed it, one of the best sets ever, although not as fine of a picture as the now extinct Pioneer Kuro plasma sets.

Sony's engineers went to remarkable lengths to create it, almost as if the ghost of Sony's founding fathers came down and rekindled the engineering pride of the company, telling them to spare no measure to create the TV. "Use LEDs! Use three or four of them for every one those bastards in Korea do!" What resulted was a unique set of discrete red, green and blue LEDs—two of the dimmer greens in every triad— repeating the set up into a backlighting array. Each of the different color LEDs would be calibrated in real time, adjusting for color and brightness output. And that's after they were matched for similar qualities. Apply localized dimming, for a set only an LED fanatic could dream of. And the result was fantastic but without implying anything about its reliability, it is curiously prototype-like in many ways.

The set's large number of discreet color LEDs makes it heavier, more power hungry and thicker than most LED LCD sets, fitting somewhere in physical profile between other LED LCD sets and plasmas. A year and change after its revolutionary release, the set finds itself in murkier waters that make it impossible to justify its extravagance—another hallmark of cutting edge prototype-like technology. And there's competition. Kind of!

Having said how wonderful it looks, this set is a strange creature, born right before the economic crash wiped out the chance that high end sets, like Mitsu's laser TV or Pioneer's Kuros, would sell well. Yet it exists at the same time as its cheaper and poorer performing successors like the Non-LED XBR9.

Markets equalize all. Right now, the XBR8 still has a wildly expensive, with an MSRP of almost $4000 for a 46-incher. Thankfully, because of the set's age, they're going for $2600 on Amazon, which is better, but still over the MSRP of some competing sets that look almost—almost—as good. The XBR9 is $2600 MSRP and can be had for under 2 grand. For about the same price as the XBR9, you can get the LG LH90 in a 47 inch size, backlit by white LEDs with localized dimming. David K. over at CNet says its almost as good, visually.

Somehow, I'm still drawn to the only shipping LCD that uses separate red, green, and blue LEDs. Maybe once the retailers forget how special it is, and the final units are put on clearance as last year's model, I'll pick one up at a steal. More than likely, that sub $2k price point will fill up with better and better sets using simpler and more production friendly technology that'll make me wonder what I was lusting about in the first place. Until then, I still love the XBR8. And without any benchmarks, you'll just have to take my word for it that this set is something special, if not also an unrealistic set to own.

If you think the picture quality might be off, follow this guide and learn how to calibrate an HDTV on your own. And, for the love of God, don't waste money on this service from a big box store.

The company has told Forbes that "several 'powered by Chumby' gadgets" will launch in the coming months. They have struck partnerships with Sony, Samsung, Broadcom and others.
