Its max is 1680 X 1050. If you have the higher resolution available, it seems your display claims to support it. It's possible (I don't know about your display in particular) that there's a menu you can use to try and fix it. There are times I change my resolution and the picture is way off- center. This happens mostly with the SVGA connector, not the DVI. If that happens, I can fix it with an Auto-adjust option in my display's menu. Eric
