I'm getting ready to purchase my first hi-def tv and I've narrowed it down to either a 37 or 42 inch lcd 720p, 1080i set. 1080p is just too far out of my budget. I think I've read somewhere that the ps3 has an issue through the hdmi output if the set isn't capible of doing 1080p. If I remember it downgrades it to a 480p signal? If that is the case, what connecting cable (composite, component) would get me the best output?
