Tweaks can't save low-buck LG's picture quality

by David Katzmaier
  • 2 comments

LG's LH20 series has more picture adjustments than any TV in its class.

(Credit: Sarah Tew/CNET)

We can't fault the LG LH20 series for trying.

The company's least expensive lineup of LCDs for 2009 offers more features than the competition, including the only USB port for digital photos and by far the best selection of picture adjustments. All of those tweaks allow users to dial in superb color, but color accuracy only goes so far when black levels look gray instead.

But as long as you don't expect deep blacks from your entry-level LCD (and why should you?), the LG LH20 series still has a lot to offer for a tempting price.

Small Samsung LCD TV earns budget laurels

  • Post a comment

The Samsung LNB360 performs well for a cheap HDTV.

(Credit: Sarah Tew/CNET)

To a bargain HDTV shopper, the array of small-screen LCDs must seem inexhaustible and indistinguishable, but among recent models we've reviewed, the Samsung LNB360 stands out with the best picture quality. It's no home theater superstar, mind you, but it managed to beat out the entry-level LCD competition in the important arena of black-level performance.

It does cost a few more bucks than many of its competitors, and it lacks some noteworthy features (like side-panel inputs), but if you're looking for a small LCD that gives "good enough" picture for less, the LNB360 series certainly qualifies.

Vizio interactive HDTVs delayed until January

by David Katzmaier
  • 4 comments

Shoppers anticipating the release of the Vizio VF552XVT will have to wait until after the holidays.

(Credit: CNET)

Remember when we crowed about Vizio's upcoming lineup of "Via"-branded TVs, citing a prodigious feature set that includes local dimming LED backlighting, interactive add-ons galore, Wi-Fi connectivity, and a QWERTY-equipped Bluetooth remote (pictured), all for an appropriately Vizio price?

Since then we've received lots of e-mails asking when the Via models would be available, and we dutifully repeated the same question to Vizio's reps. Now it's been answered: the company is officially pushing the Via models back until January 2010.

Vizio Bluetooth remote (Credit: Vizio)

Assuming Vizio can deliver even a passable interactive experience, we expect our eventual review of the "Via" 55-inch VF552XVT to brim with accolades despite the delay. That anticipation is based primarily on our recent review of the excellent VF551XVT (itself a past victim of a too-aggressive Vizio release date announcement). It's basically the same TV, minus the interactive doo-dads, and miraculously its lifespan prior to being replaced by its Web-ready brother has been effectively doubled by the new anticipated release date.

Of course, much like at the contemporaneous NFL playoffs, anything can happen at CES 2010. Vizio's lead in the features standings will face stiff challenge from other HDTV makers' CES announcements, which are sure to be chock-a-block with keywords (Netflix, YouTube, Facebook, Rhapsody) and may even include a QWERTY Bluetooth remote or two. Let the anticipation begin again.

Sony's smaller LCD competes well against bargain models

  • Post a comment

The KDL-L5000 series is surprisingly affordable, for a Sony.

(Credit: Sarah Tew/CNET)

When you compare the various entry-level LCDs in the price range of the Sony KDL-L5000 series, you'll notice a few that cost a bit less. But for a Sony, this set is remarkably affordable, and its design, anchored by a sleek exterior and Sony's typical remote and menu prowess, stands at least a cut or two above that of most HDTVs in its class. Its picture quality also hits most of the right notes, despite a uniformity hiccup and imperfect color accuracy.

Finally, the feature set has a few extras not often found in this price range, including a smattering of power saving modes and that third HDMI input. If you don't mind spending a couple bucks more than you absolutely need, the Sony KDL-L5000 series deserves consideration.

Vizio's entry-level LCD not especially green, but still a good bargain

by David Katzmaier
  • 2 comments

The Vizio VO320E is one of the least-expensive 32-inch TVs on the market.

(Credit: Sarah Tew/CNET)

Vizio chose to adorn its VO320E 32-inch LCD with claims of environmental consciousness, saying the little set exceeds Energy Star guidelines by 15 percent. But that's not a very high standard, and according to our tests the Vizio, while definitely no power hog, sips just a couple bucks less juice per year than other LCDs in its class. Its true appeal is low price combined with perfectly acceptable picture quality. A couple of flaws might give black level sticklers or dual-use PC/TV aficionados pause, but other bargain hunters should consider this entry-level Vizio among the better LCDs in its class.

Toshiba LCD produces (slightly) deeper black levels

by David Katzmaier
  • 3 comments

The basic styling of the Toshiba AV502U series befits its low price.

(Credit: Sarah Tew/CNET)

When we say the entry-level Toshiba AV502U series can produce relatively deep black levels, the key word is "relatively." It's perhaps more accurate to say that its shade of black outdoes most other less-expensive, lower resolution, small-screen LCDs we've seen by a narrow margin. It does fall short of the competition in terms of maintaining accurate color at every brightness level, however, and it will look best if you avoid feeding it any 1080i sources. Speaking of looks, the AV502U is also among the most boring-looking TVs we've seen when it's turned off, and that's saying something. Those caveats aside, this little LCD does do slightly better blacks for less, and that might be enough for bargain hunters.

Sony Eco TV turns off when you leave the room

by David Katzmaier
  • Post a comment

That little eye in the midst of the silver speaker is a motion detector.

(Credit: Sarah Tew/CNET)

In case you haven't noticed, "green" is big business. One way for HDTV makers to cash in on the public's craving for efficiency is to label a TV "eco-friendly." Sony's KDL-VE5 series does just that, but unlike a lot of so-called green electronics, this TV can actually save power in a new, potentially very effective way. That's because it incorporates a "presence sensor" that can automatically turn the picture off when it detects nobody's watching.

Amazingly, the feature worked pretty well in our tests, and we hope to see similar automatic turn-offs in future televisions--as long as irate couch potatoes don't flood Sony's customer service call centers to complain of malfunctioning TVs. Otherwise the Sony uses about as much power as a typical LCD--it's nowhere near as miserly as the LED-backlit Sharp's LC-LE700UN series, for example.

The KDL-VE5 also offers very good picture quality for a standard LCD, but on the downside, it charges a hefty premium over the step-down KDL-V5100 series--the only major differences between the two are styling and the VE5's presence sensor. If you're prone to forgetting to turn the TV off, however, the KDL-VE5 might be able to make up the difference in a few years.

Test pattern exposes more issues with dejudder processing, but does it matter?

by David Katzmaier
  • 10 comments

Dejudder processing on 120Hz and 240Hz TVs can cause all kinds of artifacts.

We've often complained about the video-like look of dejudder processing circuits like Samsung's Auto Motion Plus (AMP), Sony's MotionFlow, and LG's TruMotion found on those and other companies' 120Hz and 240Hz equipped LCDs. Using a process called Motion Estimation/Motion Compensation (ME/MC), they remove some or all of the judder from 24-frame, film-based sources, producing a look some viewers prefer. For the record, we strongly prefer to leave these modes turned off.

But in addition to that videolike smoothing effect, the processing also causes further image degradation. We've documented numerous such instances, which often appear as halos, trails and other unnatural effects clearly visible in program material, especially during medium to fast movement, such as an actor turning his head quickly during a closeup.

Now a post at HDguru.com by reviewer and industry observer Gary Merson exposes additional artifacts caused by the processing. The artifacts are visible in a video of five LCD TV makers' dejudder-equipped LCD TVs (a sixth plasma TV's wedge lacks the flashing and much of the moire). They appear as unnatural flashes and tears in addition to extensive moire that looks like confused, curving lines. The test pattern in the video originated from a Blu-ray test disc by Spears and Munsil, a copy of which is included with the Oppo BD-P83.

Samsung's dejudder processing is highly adjustable.

Using a few of the 120Hz and 240Hz HDTVs I have in my lab at the moment, namely the the Samsung UN46B7000 and LN52B750, the Sony KDL-46VE5 and KDL-52XBR9, and LG 47LH50 and 47LH90, I was able to confirm the Guru's results using the Spears and Munsil disc played via a PS3 at 1080p/24. The flashing artifacts were indeed visible with the dejudder circuits turned on, and disappeared when they were turned off (the flashes and extra moire can appear subtle in the video, but in person the difference is much more obvious). ...

LG PS80 plasma TV series streams Netflix, Vudu, YouTube, local media, kitchen sink

by David Katzmaier
  • 1 comment

The media-rich LG PS80 is also one of the most stylish plasmas we've seen this year.

(Credit: Sarah Tew/CNET)

When LG announced its LG PS80 series of plasma TVs at CES 2009, the series earned one of our three nominations for Best of CES in the TV category. We've already reviewed the other two nominees--Panasonic's G10 plasmas and Vizio's VF551XVT LED-based LCD--and both scored higher than the PS80. It's not that we're disappointed in the interactive features that originally caused us to nominate the LG. Those include built-in Netflix streaming, which is still an LG exclusive (at least until Sony turns its own version on, or Samsung or Vizio step up), Yahoo Widgets, and YouTube capability. Since then LG has also added the high-definition eye candy of Vudu's on-demand video rental service. Those interactive add-ons work great, and combined with LG's picture adjustment prowess they comprise the most impressive features list seen on any plasma this year.

Unfortunately for the PS80, its picture quality impressed us less. Its lighter black levels are the main culprit, abetted by it below-par video processing and even minor image retention--all areas that other plasma TVs outperform the LG. On the other hand its color accuracy is still very good, and of course it enjoys the off-angle fidelity of plasma that easily trounces any LCD. Armed with superb style and that stellar features list, the LG PS80 might still appeal to people willing to focus less on picture quality than on built-in content options.

LG: OLED will fall to LCD price levels by 2016

LG OLED TV

LG's 15-inch OLED TV, which is set to go on sale in Korea by December.

(Credit: Erica Ogg/CNET)

On the heels of announcing a 15-inch OLED display going on sale in Korea this December, LG predicts that prices for panels using the coveted technology will fall below those of LCD panels in seven years.

"Forty-inch and larger OLED panels will be fairly expensive in 2012, but they will be available in the market," said Won Kim, VP of OLED sales and marketing, at a trade show in Japan yesterday. "OLED panels will cost less than LCD panels in 2016."

Allow me to dissect that prediction for a moment. Calling the affordability of any technology so far in advance is pretty bold, but 7 years is a long time and a lot can happen between now and then. But I think the main message to be gleaned from Kim's words for customers watching the market and still waiting for OLED is: don't.
