My Optoma GT750 doesnt recognize 1080i or 720p, when i insert the hdmi from my dish network unit or xbox360 it automatically shows a 2160 x 1080 something like that or 1280 x 720, whats wrong?...i actually try this with my Optoma HD20 and no problem showing the 720 and 1080i resolutions, any help will be much appreciated.
