I'm looking at 42-45" LCD TVs. I want to get the works, HDMI, 1080p; for DVDs, PC and Xbox games, HD cable. But also for regular SD TV. I keep reading in reviews that this is an area where flat screen technology is overqualified and the results suffer. But I am reading here in this forum that many flat screen TVs allow for many different signals including lowly SD. Does it look ok? Could someone clear this up for me?
