Once I upgraded my room of doom 3.0, I did a couple of things. First I tried to hook many systems older to my HDTV. I then noticed that they looked like crap. I would say hook up you PS3, 360, Xbox, DC(VGA port), up to it. Everything else will look better on a CRT. I hate to say that but HDTV really makes older systems look pixelated and bad...in my opinion.
