I have come to notice that a small amount of soft light in the room can have a very notable impact on my TV's display, for the better. I have no protective shield so glare isn't an issue. My HT room has no windows so I have pretty good control over how much light there is. I know some people put small lamps behind their TVs to combat eyestrain/fatigure. But I've also noticed that a small amount of light in the room actually improves the display on an RPTV. I'm not sure how to describe it other than it "smooths" out the image and really does make it look more "theater like". Is there a theory or consensus behind this about how much light can be used and where to place it, ideally, in relation to an RPTV? I guess it's not a real surprise since I've noticed that most theaters don't completely turn out the lights when the film begins..
