I've had my 360 hooked up to a crt tv and had no input lag at all. Now, I brought the same tv and 360 to my dorm at college and there's a slight lag between the controller and what appears on the screen. I can't figure out what's causing the delay. There was never any lag with this tv before. Is there some kind of interference with the wireless controllers? Is the tv busted? I'm so confused! What can I do?
