I'm playing on a 46" Samsung LED. It's bottom in it's class in price, but top of it's class in lowest input lag. It's 1080p@60Hz. I make sure to shut off any hardware image processing features of the TV by using PC mode. I don't see any reason to go 4k, as current gen consoles don't support it. I wouldn't use a Plasma TV for gaming, as they are known to "burn in" images when playing video games.
