No there isn't any problems with plugging your plasma screen with xbox or ps console. All you need to make sure is that you have the right cables (rgb, component cable etc..).

If you are using a plasma, all you need to be concerned about is plasma burns, just say the game always have a frame that doesn't change and you play that games for hours on end, those mark may burn your screen. You may want to look at other alternatives screens to play on or other games to play.
