Olevia 747i

?

Those kids of yours, the ones you're always bragging about? This47-inch LCD is better than them. It's smarter, with a killervideo-processing chip that helped it ace all our tests, syncing up andsmoothing out the noisiest screwball video we threw its way. The set'sbetter looking than your brats, too: Our Blu-ray movie wastheater-quality, with a sharp-yet-natural, noise-free picture andvivid, well-balanced color. We loved its default settings, but Olevia'smyriad picture, audio, and setup controls make home-schooling this babya breeze. And, unlike your spoiled spawn, it listens. Even its soundimpressed us, a rarity for flatscreens. But then, your kids canprobably really crank up the volume, too.?

       

• Pretty, tough
          A thick sheet of glass covers the        entire front of the set, giving it a slick appearance and protecting        the LCD panel beneath. Best of all, you can clean it with Windex.       
  
• Real speakers — or none
          Two full- size speakers        mounted underneath deliver deeper bass and fuller sound than any TV in        our test. In tabletop mode, they look built-in. But they're removable        if you've got better ones.       
  
• Precise control
          Olevia's creative 3-D rolling-        hexagon menus not only look impressive, they also offer easy and quick        access to crazy-detailed configuration options. You can even adjust        picture/audio timing to sync up those old John Wayne flicks.       
  
• Magic wand
          The programmable remote can control a        DVD player, VCR, audio tuner, and set-top box, plus three other user-        selectable pieces of gear. And you'll have no trouble finding its        large, backlit buttons in the dark.

Toshiba 42HL167

?

A harmonious balance: Blacks are warm, and whites aren't blinding.Colors are muted (but accurate) and promote a very clear image. Thoughits noise-reduction software doesn't clean up as much graininess asother TVs in our test, the overall result is subtle and pleasing. Itwas good enough that we almost enjoyed our test flick, Eragon.?
WIRED: 1,920 x 1,080 native resolution means you see true 1080p. Second-highest overall score on our processing tests.
TIRED: Mishandles some film-based HD sources, which could spell lost resolution.

Westinghouse TX-47F430S

?

Hey now! Westinghouse has a lot more to brag about than just ironsand lightbulbs. Its 47-inch LCD cleaned up and correctly displayed awide range of HD sources. But it took some work: After we removed adrop of contrast, added a smidge of brightness, and adjusted tint,oversaturated colors and darkness gave way to a great image.?
WIRED: Top scorer on video-processing tests. Great price-to- performance ratio. Slick basic case looks hot and will age well.
TIRED: Laggy menus reminded us of the dialup days. Noise reduction isn't adjustable, but menu transparency is — huh?

Panasonic TH-42PZ700U

?

We'd love this 42-inch plasma if we couldn't buy Toshiba's set and anewly discounted iPhone for the same price. Our Blu-ray movie lookedgreat on it, with rich colors and lots of contrast. But we foundPanasonic's noise reduction heavy-handed, creating blocky imageartifacts. Thankfully, it's easily disabled, leaving a good — ifslightly noisy — picture. ?
WIRED: Displays photos and plays music from USB drives and  camera-friendly SD memory cards.
TIRED: Back-breakingly heavy. Can't findcadence of all HD sources, which can lead to loss of resolution. Standis a bitch to assemble.

Samsung LN-T4065

?

Though it delivers a well-balanced movie picture requiring almost notinkering, the Samsung 40-incher's colors were a little subdued for ourtaste. The set performed admirably in our gauntlet of signal-processing tests and offers a slew of digital and analog source inputs,but at this price, we'd get a 47-incher and suffer the plug-swapping.?
WIRED: Good noise reduction. 15,000:1 contrast delivers dark blacks but not a dark picture. Swivel stand. Plays media via USB.
TIRED: Couldn't catch the cadence of some HD sources, producing  a ton of jaggies and visual artifacts.

Sony KDL-46W3000

?

Sony's 46-inch set has some issues and is expensive as hell, butit's also gorgeous, so you'll want one anyway. While colors wereperfect out of the box, you can adjust them with a system that smacksof $10K-plus custom-install projectors. Its metallic earth-tone casemay set it apart from the masses, but it flunked all but one of ourprocessing tests. ?
WIRED: Hi-res menus slide in and fade out like videogame effects. Does a great job of scaling up standard-def TV and old DVDs.  
TIRED: Expensive. Clumsy noise reduction produces a swirling effect. Lots of jaggies and moir  in 24-fps HD test sources.

Vizio VX42L

?

The 42-inch Vizio's low price doesn't quite excuse its limitations.Even after we adjusted the hell out of it, our test model's pictureremained slightly oversaturated and red-tinted. Harsh blacks and whitesalso detracted from the viewing experience. However, the Vizio's noisereduction was surprisingly smooth and natural.?
WIRED: Love it/hate it glowing Vizio logo. Inexpensive. Remote  is easy to use. Picture-in-picture.
TIRED: Love it/hate it glowing Vizio logo. Had trouble displaying 24-fps sources smoothly — despite boasts to the contrary. 720p.

Polaroid TLA-04011C

?

Offering 720p in this size category is like bringing a knife to agunfight. Still, our Blu-ray movie looked decent on Polaroid's low-buckmachine. But as Momma told us, you get what you pay for. (Or was itthat girl we met on Nerve.com ?) Adjustmentcouldn't clear up its color problems fully, and its noise reductioncreated a distracting pulsing effect in some video. We also sawghosting, indicating poor motion processing.?
WIRED: 40-inch flatscreen for well under a grand? Twist our arm.
TIRED: Mediocre performance in video-processing tests; pixel interpolation yields artifacts. Lots of jagged diagonal lines.

Philips 42PFL7432D/37

?

She's purdy, but kinda dumb. This 42-inch LCD 1080p failed three ofour five processing tests. We saw jaggies in angled lines, and whenpresented with HD sources that originated at 24 fps, the set came upwith moir and flashing. It also turned dark colors black, yielding aninky picture. Add brightness to compensate and you lose contrast.?
WIRED: Ambilight. Three HDMI ports.
TIRED: Complex menus. Maximum noise-reductionsetting turns picture plasticky; other modes are indistinguishable.Can't sync up cadence of all HD sources. Disappointment shouldn't bethis pricey.
