I am currently in the market for a 60" - 65" TV, most likely that size.
I'm also pretty into console gaming. I'm specifically into competitive fighting games.
Since timing is so strict on these games, I am extremely sensitive to input lag.
My current TV is a Samsung DLP from 2004, and it has MAJOR input lag. I didn't even know about this until about 6 months after I owned SF4 back in 2009 and ended up playing at a get together on a CRT, and my timing was totally off. I then learned about input lag, and realized my DLP had REALLY bad lag.
I ended up buying an Asus monitor that is virtually lagless, to game on. I've been using that the past 2 or so years to game, but now that I'm moving and buying a new TV, I want to try and get a TV that I can actually game on.
Right now I'm considering a Panasonic ST50 plasma TV, but I also want to see if there are any that have low input-lag in the LCD/LED side of things. I know that plasma's in general can still get some burn-in issues, and just reading over on the plasma forums I see people have had issues with that specific model. But that model has about 16ms of input lag, which is about as good as you can get on a TV from the research I've done (my Asus monitor is 8ms).
So does anyone have any recommendations for a virtually "lagless" LCD/LED panel that is good for gaming?
