Guys, thanks for the feedback.
Just to clarify some: I am using a cabinet, the Ultimate Arcade with about 27.5 inches wide of room.
My dream is a monitor that does it all. I'd like to run emulators, pc games, and plug in TV and DVD as an entertainment center as well. I'm leaning towards a samsung TV that is 27" with HD and a DVI port. Will that be leaps and bounds ahead of a regular cheaper 27 inch TV that has component input?
