I have recently purchased the above tv and am having concerns about whether it is compatible with High Definition. The 1080i format is out, thats fair enough, but I was told by Sharp prior to purchasing that it would accomodate 720p. Now there is nothing in the manual to this effect, and looking at the specs, the DVI connection is for pc only and runs at 60 mhz. I have read somewhere that for High Def 50 mhz is required. I have a modded xbox, and have recently purchased the High Definition kit which uses Component. I should be able to get 720p when running in NTSC mode but the most my lcd will display is 480p in NTSC and 580i when running in PAL mode. Can High Def run through Component or does it have to be DVI or HDMI?? Any help is appreciated in what is turning out to be a AVphile's minefield!!
