Thanks for the replies guys! I found a VGA cable and a DVI adapter and switched to that and it fixed the problem. full screen HD!
BUT what you guys describes seems to be exactly the problem. i changed an overscan setting on my monitor and it fixed it slightly but not fully so i changed it back. but that link seems to be exactly right! so now i wanna switch back! will prob do it tomorrow tho.
would there be much difference between the VGA and HDMI cable? just wonderin!
Thanks again guys!
