The Vizio M3D651SV is a middle-of-the-road LED performer in a dark room, but when the lights come up it has more problems than usual. The extremely glossy coating on its big screen serves to cause reflections -- such as the one in the photo leading this review -- rather than adding to the perception of contrast. Black levels were relatively light, and the TV simply didn't have the guts to portray shadow detail convincingly, leading to flatter pictures overall. Colors were acceptable though a little too blue, but at least saturation was well accounted for with bold-yet-natural colors.

LCD TVs are generally creatures of the light. Despite everything TV makers do to try to present inky blacks, there's essentially a ruddy big flashlight behind the picture. The Vizio M3D651SV doesn't even try here, and its difficulties with black portions of the picture were evident no matter what I tried. The best-case scenario was a crushing of low-level blacks compared with its competition, but this led to a much less lifelike image. It also had the lightest blacks of any of the five televisions in the room.
When viewing the mining-ship fly-by in "Star Trek," the 65-inch Vizio demonstrated the least amount of detail of the lineup. This shot from the movie has a lot of colored shadow detail, and on some TVs the image looks very spiky and foreboding. Via the Vizio, I couldn't see any detail on the ship due to low-level black crushing.
However, in the next scene, as Nero lies on a green table, there was some detail available in the shadow next to his head, and while this was better than on the 55-inch Vizio, it was the only instance I saw where the smaller set didn't trounce the larger. This was especially true of the very-dark "Harry Potter and the Deathly Hallows Part II," where the 55-incher looked more dynamic and was able to give form to more of the murk. While the 65-inch was able to add more punch to light areas of the picture in the two bright scenes toward the end, it came at the detriment of shadow detail. A gray, withered tree set against the sky (Chapter 19) looked like a stark black-and-white render on the 65, while it looked like an actual tree with knots and branches visible in the shadows on the 55.
Color, despite what the graphs might say, was actually pretty good in a "sort of bluish" way. Color saturation is half the battle, and images had fully fleshed-out colors with intense blues and greens. Only the deepest had a tendency towards purple, but at least skin tones were natural.
The blue cast couldn't be corrected, unfortunately and it was particularly noticeable in darker colors. In the Creation sequence from "The Tree of Life" there is a shot of cells forming. On the other TVs -- Sharp, Panasonic LG, and 55-inch Vizio -- the cells were a flat gray, but on the 65-inch Vizio they were bright blue!
While color banding or "false contouring" is not a problem we specifically test for anymore, it's worth noting that the Vizio 65-inch dealt well with the bands that can appear in "The Tree of Life's" Creation scene. Its smaller 55-inch sibling and the Panasonic ST-50, for example, couldn't cope, displaying distinct bands in the many light-filled explosions appearing onscreen.
However, the 65-inch Vizio wasn't able to do all that well in our formal image processing tests, with judder in the 24p test and moire appearing in the stands of the 1080i film test. What this means is that the TV isn't as capable of replaying movies as it could be, and for a TV that costs almost two grand, that's disappointing.
Lastly, motion resolution was about average for a 240Hz TV, with a result of 330 lines without processing and 1080 lines when dejudder (smoothing) was enabled.
For an edge-lit screen, the uniformity of the Vizio was fairly impressive. There was only a slightly lighter patch in the top-left corner, and this was much better than the otherwise-superior Sharp LE640.
Off-axis viewing was actually fairly good, with only a faint purple to black and a dulling of colors.
Ready for the bad news? This has to be one of the glossiest screens I have seen in years. Years! It is truly mirror-like, and in a well-lit room it can become very distracting, particularly due to its sheer size. If you plan on buying one of these make sure to use it in a light-controlled environment; otherwise, the ensuing reflections could result in significant eyestrain.
The 3D performance of the TV was one of its best attributes, due to the lack of superficial pop-out effects and an absence of crosstalk. The only negative -- and this is amplified by its size -- is that there is noticeable interlacing-like artifacts in light areas of the picture. For the low cost of entry and the one or two movies you'll probably end up watching, it's entirely acceptable. Light output was also good, as it was much brighter than the other Vizio, and on a par with LG LM7600. It should be noted that line structure was also visible on these two TVs as well.
