Alrighty. We've just gotten a Dell projector that we're mounting on the ceiling in our sitting room, with a home theater receiver soon to be added. The receiver we're getting has several component I/Os, but no DVI (nor HDMI, for that matter.) The HDTV tuner, though, does have DVI and HDMI output. Our projector has inputs for all three (DVI, HDMI, and component.) While component can carry 1080p signals, I've heard that HD across DVI or HDMI is noticeably better than across component. My question is this: is it worth buying another cable, stringing it through the attic, and not running everything through the home theater receiver to get HD across DVI rather than component?
