When I use my hdtv as a monitor it cuts part of the screen off (the actual display goes past the screen) it does this no matter what resolution I put it on. I have a AMD Radeon 7690m and Intel Family HD graphics. Its a Toshiba Regza 1080p tv (either 30 or 32 inch I cant remember) I have a 2670qm processor if that is any help. Any advice?
This is absolutely normal for Consumer televisions. They almost all have 5-10% overscan built in to accomadate broadcast television. Without it, a lot of standard broadcasts will get odd color artifacting on the edge of the screen. Some tvs, mainly flat panels have a pc mode for this, and some have an option called pixel by pixel, or dot for dot to remove the overscan.
edit. your tv has a dot for dot mode in the theaterwide modes:
THEATERWIDE MODES: Full/TW1/TW2/TW3/Natural/4:3 HD/Native/Dot by Dot
