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.
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-LE700M-series, for example.

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." Read more »
LCD TV makers have always charged a premium for LED backlighting. In fact, the first LED-based LCD TV Sharp released, the inch-thick XS series, debuted last year at a cool US$11,000 for the 52-inch model. LED has become a lot more mainstream since then, and so have Sharp's ambitions for the well-marketed backlight technology. The Sharp LC-LE700UN series encapsulates that progress toward the mass market: it's the least-expensive LED-backlit LCD available today, it measures the standard 3-odd inches thick, and as a result, its owners will have a tough time convincing visitors that it's anything more than a normal, CCFL-based LCD.
This Sharp uses different LED backlight technology from any of the other "LED TVs" available today, and perhaps as a result its picture quality has no major advantage over non-LED-based LCDs. On the other hand, it sips power more sparingly than any other TV we've reviewed, and its solid feature set is highlighted by a unique selection of widgets and superb built-in support options. The Sharp LC-LE700UN series will appeal to people on a moderate budget who still want the energy efficiency of an LED-backlit LCD.
Samsung, with the help of video guru Joe Kane, again delivers outstanding performance in the high-end front-projection DLP category with the flagship SP-A900B. This 1080p resolution, one-chip DLP projector sports the latest Dark Chip 4 chip from Texas Instruments, but otherwise appears virtually the same as the SP-A800B that CNET projector reviewer Kevin Miller loved last last year.
The new chip results in superior black levels, which also increase the contrast ratio of the projector substantially. The 900B retains the same superb color found on its less expensive brother, along with its other stellar image quality characteristics, and as a bonus remains one of the most stylish and attractive designs in front projection. At US$12,999 list, the Samsung SP-A900B is definitely on the pricey side for the one-chip DLP category, but as with so many things in life, you get what you pay for.
