This is my first post on this forum so I hope it's in the right place. I'm looking into buying a rear projection TV and want to know which resolution is better, 1080i or 720p. I notice on LCD and DLP set that the highest resolution is 720p and on CRT sets it is 1080i. I've heard that right now only CRT and Plasma sets are capable of 1080i so does that mean it translates to a better picture. Also, should I find out from my cable company which resolution they transmit their HD in? Do some transmit in 720p and some in 1080i and should I base what TV I buy based on that? Hope this makes sense to somebody. Thanks.
