intro
The plummeting prices of flat-panel HDTVs has been big news for the last couple of years, and in 2006, the latest downward price trend is among flat-panel LCDs in the 40- and 42-inch size range. Vizio, that popular purveyor of price-savvy panels, is once again surging to the bottom with its entrants, the 42-inch L42 HDTV and its slightly more-expensive and arguably better-looking brother, the G42L HDTV. Both have nearly identical feature sets and picture quality, but we'll deal with the G42L HDTV separately. This review is of the Vizio L42 HDTV, which at the time of this writing sells for $1,599 online and even less in select stores. Its price alone makes it a great value, but unlike many cut-rate HDTVs, the L42 HDTV also boasts enough features for just about anybody, as well as picture quality that will leave most viewers believing--rightly--that they got a great bargain. We thought the Vizio L42 HDTV looked stylish enough but not stunningly attractive. It consists of a black frame surrounding the 42-inch-diagonal screen that's in turn mounted above silver speakers. In this case, the frame is thick and glossy black, and despite appearing detachable the speakers are indeed fixed. Aside from prominent HDMI and Vizio logos, there aren't many features on the set's front.

Atop the included silver stand, the L42 measures about 41.3 by 29.8 by 11.4 inches (WHD)--a bit bigger than some 42-inch flat panels--and weighs 73.3 pounds. Like all flat-panel HDTVs, it can be wall-mounted with a special kit such as one available directly from Vizio.

The Good

Inexpensive for a 42-inch LCD; relatively deep black-level reproduction; ample picture controls; comprehensive connectivity with two HDMI and one PC input.

The Bad

Nondefeatable edge enhancement; inaccurate color temperature presets; less compact than some 42-inch flat panels.

The Bottom Line

The Vizio L42 HDTV leads the affordable big-screen LCD charge while managing to produce a perfectly acceptable picture.

The company includes its standard, nonbacklit remote, which we've always found to be too busy, with too many keys that don't have enough differentiation. We did appreciate the direct-access keys for different inputs, however, and the fact that the clicker can command three other pieces of gear. Hitting Menu brings up a typically drab-looking array of options, but Vizio covered all of the basics. Once again, Vizio has included enough features to satisfy just about everybody without missing anything major. The Picture section of the L42 HDTV's menu offers three presets that cannot be adjusted, as well as a fourth Custom mode that's independent for each input. You can choose from three color-temperature presets or adjust red, green, and blue gain yourself in a fourth custom mode. We appreciated the last option, since the L42 HDTV's three color-temperature presets were really far from the standard (see Performance). There's also an adjustable backlight control that allows you to turn the intensity of the lamp behind the screen up or down. It's worth noting that backlight and color-temperature settings are global and cannot be saved individually for each input.

Other features include picture-in-picture, which offers a side-by-side option, too. There's also a freeze mode that's handy for catching quick information, such as the fine-print of disclaimers in drug ads. Vizio's selection of aspect-ratio controls is average: three for high-def sources and four for standard-def. And as its name indicates, the L42 HDTV is in fact a full HDTV, meaning that it includes an ATSC tuner for grabbing over-the-air high-def and digital stations.

Around back, you'll find a healthy selection of inputs, including the requisite pair of HDMI jacks. Other inputs include two component-video, one A/V input with composite and S-Video, one A/V input with only composite video, and one VGA-style RGB computer input. There's also a single RF input for connecting an antenna or cable, an analog audio output, and an optical digital audio output for passing surround soundtracks from over-the-air HD sources. In sum, the Vizio L42 HDTV's image quality was very good for the price, with relatively deep blacks, accurate primary colors, and solid standard-def reproduction. It did exhibit some murky shadow detail, and its out-of-the-box color temperature definitely needs adjustment, so videophiles will probably want to consider paying a bit more for a better-performing set.

To evaluate the L42 HDTV's picture, we first adjusted the picture parameters for viewing in our dark lab. We quickly realized that the preset color temperature modes--Warm, Cool, Normal, and Custom--were all very different, and surprisingly, only Cool anywhere near the standard (see Before in the Geek box below). Typically Cool is the least accurate, but in the Vizio L42 HDTV's case, that dubious honor went to Warm, which tinged the picture with an unacceptable amount of green. Fortunately, the set does offer adjustments to RGB gain in its Custom settings, and after we adjusted their values appropriately, the color temperature was much improved. See the Tips & Help tab above for those adjustments, as well as our complete dark-room settings.

When we settled back to watch a movie--in this case, Syriana on HD-DVD via the Toshiba HD-A1--we mostly liked what we saw. In darker scenes such as Jimmy Pope's fireside chat with Bennett Holiday, the depth of black in dark areas was fairly good for an LCD; not quite as deep as some we've seen, such as the Samsung LN-S4051D's or the Sharp LC-37D90U's, but still pretty dark. We had a couple of more-expensive like-size LCDs onhand to compare--namely the Vizio's step-up brother, the G42L HDTV, the Philips 42PF9831, and the extremely expensive Sony KDL-40XBR2--and the Vizio L42 HDTV's depth of black was just slightly brighter than that of the Sony and the other Vizio, and significantly darker (better) than the Philips's.

The Vizio L42's shadow detail was a bit worse than that of the Sony, however. During the next scene with CIA agent Bob Barnes, the chairs and stools under the bar appeared slightly murkier with less of their legs and seats visible in the shadows. We also noticed a bit more false-contouring on the Vizio than on the Sony. During Barnes's interview with Hezbollah, for example, we saw the faintest lines in the shadows on the wall behind the leader as they faded from light to dark. It's worth stressing, however, that contouring overall with the Vizio was minimal--far less than the aforementioned Samsung's, for example, and most viewers won't fine it objectionable at all.

We did notice a few somewhat brighter areas in the screen, especially when it faded to black, such as immediately after Barnes is tortured. In the case of our review sample, the upper-right corner and the edge immediately below appeared lighter than other areas, as did a few areas along the top edge. These lighter spots will vary from sample to sample, although it's worth noting that the Sony, unlike the other Vizio and the Philips, was consistently black across the screen. The Vizio L42 HDTV's image became more washed out starting at about 45 degrees from dead center, which is average among LCDs we've seen, but not spectacular. It's worth noting that plasmas look good from extreme off-angles, while on the flipside, their glass screens reflect more light than matte LCDs.

After we'd adjusted color temperature as described above, the L42 HDTV exhibited commendably accurate color for an LCD. There was no trace of red push in skin tones, such as the face of Julie Woodman as she argues with her husband in the park. We did see a bit more yellow than we'd like to in green areas, such as the grass through which Mazar and Shahid walk on their way to see the shaped-charge device, but it wasn't too much worse than many LCDs we've seen.

Likewise, details were as good as we'd expect for an LCD of 1,366x768 resolution. On the HD-DVD, the blades of grass and trees looked sharp and lifelike, and we could discern the mesh in the Mazar's white cap. We did notice a few signs of edge enhancement that couldn't be removed despite reducing sharpness to zero. In an overhead shot of Barnes after the torture, for example, we saw slightly unnatural-looking brighter edges along the black grid of the tiled floor. Again, the effects were subtle.

With standard-def sources, the Vizio L42 HDTV did a solid job, although we do wish it had some kind of noise reduction. During the noisy shots of skies and sunsets from the HQV Benchmark DVD, for example, the snowy video noise was relatively prevalent, although not overwhelming. We did appreciate the quick engagement of 2:3 pulldown detection, and the Vizio did an above-average job of smoothing out jagged edges in diagonal lines. Via component-, composite-, and S-Video, we did notice that some images appeared a bit softer than they should have, but not terribly so.
