Just picked one of these up as a refurb for $799 (involved a $100 rebate).
Out of the box the color looked impressive at first glance but after viewing awhile it's obvious Sharp is more concerned that anything yellow glares neon regardless of source material...threw off flesh tones so bad it looked horrible...
Looked at the calibration settings from page one "NEW 6500k/D65 MOVIE MODE". On my set (and this gets into variance between individual sets) the grayscale pattern looked a hint green across the board, so I tweaked the green color temp (low and high) settings down 3pts, and (revealing my preferences) turned the backlight to +6 and basic level saturation to +3.
The other sets in the house are
Samsung 50" DLP from '08 (looks good but disgusting poor black levels and no sub field processing: I find straight 3:2 pulldown quite distracting)
I wish I could pluck the smooth motion engine out of the Vizio and put it in the Sharp. I've never noticed sub field motion processing artifacts on the Vizio. Aside from a truly amazing overall PQ on the Sharp (that's difficult to put words to) it's lackluster motion engine is its only drawback, and even without a local dimming full array (which the Vizio has) the black levels on the Sharp look inky enough to pass my critical eye provided the backlight setting is kept below +8.
Mcdonalds commercials in HD are particurarly lethal on this thing. Looks as I could just reach out and grab that sandwich! (that I know wouldn't taste half as good as it looks on this screen). The Vizio looks pleasing, but never felt so deeply compelled to make a fast food run while watching it.
