I have just recently got a HD TV in my room, a 40 inch 1080p Samsung. I have connected my Xbox 360 up via Component, VGA and HDMI. Was playing Halo 3 and the whole thing was freaking cross-hair wise, looking fuzzy. I sorted this, found out the TV was setting to upconvert to 100Hz so turned this off and it's better. When I was playing Halo 3 with VGA and HDMI some edges looked jaggy, and pixily. I now have it connect via Component set to 1080p. I was thinking though, is it the input or the game, are the graphics really that great in Halo 3 or do I just expect them to be 'perfect'. So I need the best way to test my outputs, a DVD? a title screen? I can rent any game for free so recommend anything. I have read about jaggy-ness as a result of the HDMI, so I don't know, what can you suggest guys?
