I am considering going with a DLP projection screen. Weighing whether or not I should go with rear or front projection. But there is one concern I have - will DLP projection ever reach full hi-def, that is 1080p like LCOS has? And I noticed that the Sammy DLP TVs convert all signals to 720p. Is that bad when its being fed a 1080i signal? Which looks better, 720p or 1080i? Any comments?
