Help!!!!

[matt57]

ok, here's my dilemma. i have a hitatchi rear projection (yea i know it's rear projection but i couldn't pass it up for $700) 1080i display. i'm running my cable box on composites, my 360 on composites and my ps3 on HDMI. for some damn reason the very far right of the display cuts off a minute amount of the video no matter what source i'm using. i've changed every setting on every source. i can't for the life of me figure it out. also, it's not like the picture is set up too far to the right either. if that was the case there would be a black bar on the opposite side right??? can anyone help me out. i mean it's not that big of a deal it's just really annoying. it's not cutting off anything important at all, if i'm watching espn2 HD it cuts off right down the middle of the 2 on the bottom left corner.
