doobiwan : Almost every Plasma and LCD I have come across say they are HD compatible (Which doesn't mean they are HDTVs) and are merely EDTV 480p (not 720p)
Um, a lot of Plasma's are HD ready (720p and up), got mine beginning of this year i think, and there were abt 4 other models i was looking at, all HD ready.
what most plasma's do is "downscale" a HD 720p or 1080i signal to fit its native 848x450 resolution... you do get some real HD plasma's that have its native res @ 1366x768 which is truly HD @ 720p. But they do cost an arm and a leg...
