I bought the tv over black friday but leading up to the purchase I tried really hard to find information here about this TV and could not. Although frustrated, I took a gamble because of the solid price ($600 flat before CA tax) and bought it. It's main uses will be for video coming from my computer and I plan on doing some gaming on it too. Today I got around to testing input lag and thought sharing the results would be useful for possible future buyers who can't find this information anywhere else:
Video = DVI-to-HDMI adapter then HDMI cable straight to the TV from my computer's Nvidia GTX-285 video card. Audio-over-hdmi disabled in nvidia control panel.
Audio = Minijack-to-RCA cable to "DVI Audio In" I think it's called on the back of the TV.
Computer LCD Monitor = BenQ G2400 and you can find input lag information for that monitor here http://www.digitalversus.com/duels.p...&p2=3984&ph=12
which pegs it at 3ms at worst.
TV settings = Scroll down for those.
Conclusion: So at 32ms of input lag vs my BenQ I would say it's at 2-3 frames of lag. Based on what I've seen in other threads I think that is probably pretty decent.
