I just bought Sony W674 42" for my room last week. Loving it so far; though I don't know what's the best setting for games.

[attachmentid=3628328]
My settings for a bedroom:
Game Mode
Backlight: 6 or 7 (6 if I turn off all the lights)
Contrast: 93
Brightness: 49
Color temp: Warm 1
Sharpness: 50
Gamma: -1
White Balance
All default except blue gain at -2, this is to account for setting Clear White at Low
Post process settings
All disabled except - Clear White (Low) and Smooth Gradation (Medium)
Using these settings, I've managed to get delta errors to less than 3 which is the optimal limit for a mid-range LCD LED TV.
Measured gamma point is at 2.38 which is just 0.2 point away from the standard set by ITU and THX as a reference level.
Input lag with these settings is at 19ms (+4ms from an everything disabled 14.5ms W6). Rule of thumb, anything under 30ms is optimal for games, under 20ms is exceptional in today's standards. Many SF4, Blazblue, GG, MvC3 pros play on 40ms HDTVs.
*Note*
You can choose to enable Reality Creation (limit it to no more than 35 though) if you want on games which aren't natively at 720p (which sadly, is a lot of PS3 games). This sharpens images across live polys and textures as well, but it does make aliasing pop more.
Reality Creation adds about 15ms of input lag as well. I really only enable it in games where there's an excessive use of AA (again, not many PS3 games sadly).
Hope that helps.
