VIZIO SV470XVT review (47" LCD TV)

Our standard calibration went exceedingly quickly on the Vizio, mainly because its Normal color temperature mode was already exceedingly close to the D65 standard. In fact, it's as close as any TV out-of-the-box that we've reviewed recently. Our main adjustments involved turning off most of the options in the Advanced picture mode, tweaking saturation a bit, and reducing light output for our darkened home theater. Check out our full picture settings for details.

We usually try to compare Vizio displays with the other less-expensive models, but with the company's entry into high-end land, we pitted the SV470XVT against the big boys, including 120Hz LCDs such as the Sony KDL-46W4100 and the Samsung LN52A650, a non-120Hz Samsung LN46A550, and a pair of excellent plasmas, the Pioneer PDP-5020FD as a black-level reference and the Panasonic TH-50PZ800U as a color reference. In honor of a certain blockbuster in theaters this summer, we spun up an old favorite Blu-ray Disc, Batman Begins, for the majority of our image quality tests.

Black level: The Vizio SV470XVT didn't match the depth of black delivered by the other sets in our comparison. In the scene with Bruce Wayne and Henri Ducard sitting around the campfire after their sparring match, for example, the black of the letterbox bars, the shadows behind Wayne and the two black outfits appeared noticeably lighter than on the Samsung A550 and 650, and even lighter compared with the other displays. Shadow detail, such as the dark half of Wayne's face in the firelight, was also a bit less distinct than on the other displays, although it was about equal to the Samsung A550.

Color accuracy: The Vizio proved worthy of comparison with the best LCDs in this category. Its grayscale stayed solid from bright to mid-dark areas, which helped skin tones, such as the face of Rachel Dawes as she argues with Dr. Crane outside the courtroom, look natural without any undue flushness or greenish tinge. Primary colors, such as the green of the grassy field where Alfred picks up Bruce, and the red of the Gotham Post and the fire bell behind the police commissioner, looked as accurate as we saw on our reference Panasonic plasma. One negative issue we saw occurred with very dark and black scenes, which took on the bluish tinge we see on so many LCDs; the issue was worse on the Vizio than on the other LCD displays in our comparison. We also noticed that colors looked a bit less-saturated than on the other displays, a difference we chalk up to the Vizio's lighter blacks.

Video processing: The SV470XVT is equipped with Vizio's first attempt at 120Hz dejudder processing, and, in general, we feel the company could use more practice before it can compete with the better dejudder modes we've tested. Dejudder on any so-equipped HDTV is designed to lend a smoother look to film-based material, although to our eyes it makes film look too much like video--that 24-frame judder is part of what makes film look like film, and we prefer that look to the smoother appearance of typical dejudder processing, the Vizio included.

This model has four main settings for dejudder under the Smooth Motion Effect menu: Off, Low, Medium, and High. It also includes a Real Cinema option with three settings: Off, Smooth, and Precision. All of those different permutations allow more adjustment than with other HDTVs we've tested--Sony just has two dejudder strengths, Samsung three, for example--but they can be confusing. Here's a cheat sheet: in our testing, Real Cinema should be set to Precision if you want to use dejudder, because Off seemed to keep most of the judder intact, while Smooth (which is unfortunately the default for most of the Vizio's picture modes) introduced significant artifacts.

In Batman we noticed quite a few artifacts in fast-moving scenes with Smooth engaged on all of the strengths, including Low. When Bruce walks into the party at his mansion, for example, his eyebrow appears to detach slightly as he nods at an attendee, and we saw similar trails follow fast shakes of the head or strides across a room. Precision introduced fewer artifacts, in these and other scenes, although it still suffered the Vizio's main dejudder weakness: its inability to maintain a consistent smoothness. One good example came during a pan over a newsstand in Spider-Man 3. No matter which setting we chose, the smoothness disappeared briefly as the camera passed the corner of the stand, then kicked in again afterward, which was a bit jarring. Neither of the other two dejudder-equipped LCDs in our comparison had this issue. In its favor, however, compared with other displays, the Vizio (when we used Low/Precision) did introduce a slightly less-noticeable "halo" around Peter Parker's head during the beginning of Chapter 18.

We also noticed that the Vizio's dejudder modes often took a second or two to kick in, and during that time the image appeared very choppy and basically unwatchable. This issue occurred most often if we jumped from one chapter to the next or changed channels. Occasionally the ticker below channels like ESPN and CNN would become choppy as well with the dejudder modes engaged during channel changes.

We also checked for the triple puck effect, something we noticed in the higher modes on the Samsung A650, for example, where a fast-moving object, such as a hockey puck, would appear to break up slightly and become blurrier as it traveled. The Vizio was pretty much immune to this issue, although we did detect a bit more blurring and elongation when we chose the "Smooth" setting for Real Cinema as opposed to Precision or Off.

As a 120Hz display we expected the SV470XVT to improve the look 1080p/24 sources when its dejudder processing was turned off, but we found it difficult to discern any benefit to setting our player to 1080p/24 mode with this display. We checked out the pan over the Intrepid aircraft carrier from I Am Legend for this comparison. We expected to see the marginally smoother look evinced on the Samsung A650 and the Sony (with their dejudder modes off) but instead the pan looked a bit less smooth, similar to the appearance of the 60Hz displays in our test (the plasmas and the Samsung A550). This isn't a huge deal in our opinion, since the difference between the two isn't gigantic by any means, but videophiles intent on using 1080p/24 to preserve the correct cadence of film may be disappointed in the Vizio.

In terms of reducing motion blur, however, the Vizio was the best LCD in our comparison. We checked out a test disc designed to evaluate motion resolution and the SV470XVT scored better than the LCDs, although not quite as well as the plasmas. As usual, however, we found it quite difficult to discern blurring in motion on any of the displays, including the 60Hz Samsung A550--in other words, the Vizio's advantage in motion resolution according to test patterns didn't translate into a real-world difference. The SV470XVT also passed both of our tests for proper 1080i deinterlacing (see the Geek Box for more).

Uniformity: The screen of the Vizio remained relatively even across its surface for a flat-panel LCD, and there were no obvious brighter or darker areas. It did become a good deal more washed-out than the other displays in our comparison when seen from off-angle, however, an issue that was mostly visible in darker scenes.

Bright lighting: The Vizio's matte screen did a much better job of attenuating ambient light than the shinier screen of the Samsung A650 or the glass screens of the plasmas in our comparison, performing about as well in this regard as the matte screens of the Sony and the Samsung A550.

Standard-definition: The Vizio is an average standard-definition performer. It resolved every line of the DVD format, and details in the grass and stone bridge were relatively sharp. It did not remove many jaggies from moving diagonal lines or a waving flag, however--even the Sony was better in this regard. Noise reduction was effective enough, cleaning up the difficult shots of skies and sunsets quite well. The Vizio's 2:3 pull-down also engaged properly to remove moire from the bleachers behind the speeding car on the HQV test disc.

PC: Via both VGA and HDMI the Vizio performed as well as we expected, resolving every line of a 1,920x1,080-pixel source without any overscan or edge enhancement.
