CEALS 2010: Vizio

At the Vizio booth we got a look at the XVT3D654SV, a 65-inch LED-backlit LCD TV with passive 3D technology. Pros: High light output, the glasses can be manufactured for pennies. Cons: Less resolution than active-shutter 3D. The technology is baked into the panel so the set can be used only for passive 3D. Shipping and price not available. Also introduced: other new LED sets and wi-fi Blu-ray players.

Less resolution is an understatement. It will likely be half resolution for 3D sources--in other words, NOT high definition. Both left- and right-eye images must be flashed on the screen simultaneously, with opposite polarization. This means that each separately polarized eye image will occupy half of the available (1920 x 1080) pixels. If you overlay this with the half resolution 3D we're going to see with broadcast 3D (full resolution 3D for each eye will be available, for now, only from Blu-ray), the result could get ugly.The only way around this would be if a giant polarizing filter is put in front of the entire LCD screen, a filter that can switch polarization up to 120 times per second. This, combined with polarized glasses, can feed alternating, full-resolution frames to each eye. Shutter glasses do the same thing, but don't need polarization. But I can't see Vizio goint this expensive route, which leaves us with half resolution 3D from polarized glasses.

Half resolution may not actually be as bad a trade off to get 3D compared to the loss of brightness experienced with the LCD shuttered glasses for other sets. You may be able to increase the brightness for 3D viewing as with the most recently reviewed Panasonic plasma, but then what happens to the blacks? Also, with a 65-inch set, viewing distance will be around 10 feet and I am not sure at that distance that one can tell half resolution (I know telling 1080p from 1080i may be possible due to the "softer" image of the 1080i picture, but telling 1080p from 720p is nearly impossible at 10 feet).
