Vizio CinemaWide XVT3D0CM review: Vizio CinemaWide XVT3D0CM

Review Sections

Connectivity: No complaints are warranted here. The TV has five HDMI ports in addition to a component input, composite, Ethernet, RGB, and two USB ports.

Picture quality
The Vizio is a solid performer among LED TVs, scoring the same 7 in picture quality that we awarded the much less expensive Sharp LC-LE640U. Its local dimming helps elevate it in terms of picture quality above some of contrast-deficient TVs out there, like Samsung's UNES8000, but it can't match any of the better plasmas or LED models in its price range. Color accuracy was quite good, off-axis viewing and 3D have some issues, and bright-room picture quality is abysmal.

Before I tackle the standard CNET litany of tests in depth, however, I figured I'd talk here about how the XVT3D580CM handled the various types of content I threw at its wide screen. While it usually worked well, the automatic scaling to eliminate black bars was disappointing at times. Unfortunately there's no manual 21:9 mode that can force ultra-wide-screen content to fill the screen horizontally -- you'll usually have to stick with auto on this model.

One of the first problems I noticed is that presenting just the material between the black bars can severely hamper usability. I found using the menus on Blu-rays can be problematic as they often appear in the bottom of the screen in the letterboxing. As a result this meant changing the Wide Mode to Normal so I could see them.

Another issue I found was that the TV could "lose" hold of the signal and revert back to presenting it in a 1:1 ratio -- which would mean black bars around all of the movie. This usually occurred when changing aspect ratio, but on a couple of occasions (and ones I could not replicate with further testing) it happened during normal 21:9 material. After a a couple of seconds it would then revert to full-screen, but the effect was quite jarring and pulled you out of the movie you were watching. This happened a couple of times during our testing, but it's hard to say what the cause of this was -- the PS3, the HDMI switcher, or the TV itself. Suffice to say that a dedicated 21:9 mode would fix this potential issue.

When presented with a 480i source -- such as Warner Bros. cartoons-- I was quite surprised to see that the Vizio was the only TV that correctly displayed it in 4:3, whereas all of the other TVs in my lineup stretched the cartoons to fit the screen.

With the advent of 3D has come another potential trap for this TV: movies with changing aspect ratios also designed to be shown in Imax theaters. Examples I tested included "Tron: Legacy" and "The Dark Knight." During "Tron Legacy" at the 23:50 mark, as the Recognizer comes down, the movie changes to 16:9, which is quite jarring. At 26:50 the movie switches back to 21:9, and the TV took several seconds to recognize the change and then adapt. By contrast the change was subtler on a normal wide-screen TV and much less jarring.

Next, I checked how the TV would deal with aspect ratios larger than 2:4, which is a consideration if you're a fan of Hollywood golden-age blockbusters like "Ben-Hur" and the "Ten Commandments." I figured that the TV would stretch the 2.7:1 aspect of "Ben-Hur" to fill the screen; it didn't even try, making it sit in a small rectangle in the middle of the screen. "Smaller than Ben-Hur" doesn't really have the same ring about it.

And while the TV has a native resolution of 2,520x1,080 pixels, unfortunately you can't use this to display a wide desktop from your PC. While it would accept a signal at that resolution, I found it scaled it back to 1,920x1,080. Pushing the Auto Stretch button ended up with noticeable text artifacts, which made it unusable for general computing -- but gaming was a lot of fun!

And now, on to the regular tests.

Comparison models (details)
Samsung PN60E8000 60 inch plasma
Sharp LC-60LE640U 60 inch edge-lit LED
Samsung UN55ES8000 55 inch edge-lit LED
Sony KDL-55HX850 55 inch edge-lit LED with local dimming
Panasonic TC-P65VT50 (reference) 65-inch plasma

Black level: With no black bars to worry about, the apparent contrast of the panel is boosted when showing screen-filling 21:9 content. The net effect is that the TV appears to have better contrast, even when compared against TVs with deeper black levels. Blacks are relatively good for an edge-lit LCD, with the local dimming doing a fine job of providing a balanced picture without crushing dark areas. In practice though, in terms of contrast its picture looks almost identical to the Sharp LE640U's, and if you're not concerned with the width of your screen then you can pick up quite a discount by getting that one instead.

At the start of chapter 4 of "Star Trek," the evil Romulan ship glides past the camera, and the Vizio was able to make sense of what was happening with all of the flying buttresses and spiny parts of the craft. There was a sense of depth, although the Sony HX850 was able to depict the dark image in more detail.

Color accuracy: During my testing I found that the XVT3D580CM's color reproduction was accomplished and fairly consistent with that of the Sony HX850 I had placed alongside it. While neither TV is "studio-accurate," both will give you fairly rich colors for an LCD. If you're looking for deep, saturated colors, though, both the Samsung E8000 and Panasonic VT50 exhibited more vivid tones than the Vizio.

Video processing: As the TV is always doing some kind of processing on 21:9 content to fill the screen, I was interested to see if there was any difference between its unscaled competitors and the Vizio. Based on my selection of program material -- including artificial benchmarks -- it appears the onboard scaler is quite good without jaggies or blockiness, even close up.

The TV was able to handle 24p sources beautifully with absolutely no judder during our "I Am Legend" test scene. Similarly, it was able to perform well with 1080i content with no loss of detail in our synthetic tests.

Uniformity: As an edge-lit LCD the TV did show fewer uniformity problems than competitive models, though there was still a touch of light leakage at sides during some dark scenes. But compared against the Samsung ES8000 in particular, the trade-off with better blacks overall is worth it.

While blooming was not very visible on-axis, the TV was susceptible to blooming effects off-axis, with white areas of the picture being surrounded by a gray cloud on dark backgrounds. The blacks also tended to look purpler from the sides. Due to the wide nature of this TV, it's possible to be both in front of it and slightly off-axis.

One other interesting thing I noted during 16:9 viewing was that the black bars at the sides would appear darker than a "black" section on the screen, a side effect of local dimming no doubt, and not particularly troubling.

Bright lighting: It's been a few years since I've seen a TV as reflective as the Vizio XVT3D580CM, and in a bright room during a dark scene I could easily see myself reflected back. As a result I'd recommend using the TV in a dim-to-dark room, where the local dimming switch will at least give usable blacks.

3D: Despite the supposed benefits of passive 3D in regard to brightness, the 3D mode is quite dim. In comparison the Samsung ES8000 had greater contrast and therefore more pop, and as a result onscreen detail seemed better on the Samsung. Both TVs were able to deal with the "ghostly hand" from the 4:55 mark in "Hugo" without any crosstalk. But the Vizio does exhibit a tendency to show interlacing effects, and if this is distracting I'd say the Samsung is the better choice if 3D playback is your main concern.

Editor's note: The review has been updated with further testing on the Auto mode for 21:9 movies. No change has been made to the product's score.
