i have a xenarc 700ts and an via m10000n mobo. i cannot get full screen on my screen. about 1 inch from the top and 1 inch from the left are black and its not like it overlapping the image, the image is only showing in that part of the screen. The only way i can get my screen to work is by modifying the display properties>setting> advanced and choosing LCD as the monitor in the s3 display tab. however when my pc shuts down it goes back to the original problem.
