Need help determing resolution...I download powerstrip as, it has a bunch of predefined resolutions. When I set desktop to 1280x720 the height is perfect but part of the desktop is clipped off to the left and right when, I select 1920x1080i everythings fine except, the flicker that was also apparent in 1280x720p is now worse and, unreadable. Naturall...going any lower in res defeats the purpose of using a kick butt HDTV. I find that when I use 1152x648 the width is perfect but the height does not fit the screen completely. Any ideas?
