I'm running Windows 7 on an iMac using Bootcamp. At the native resolution of 1290x1200, the desktop fills the entire screen, but when I run games at a lower resolution or reduce the size of the desktop the visible area is reduced and a large black border surrounds the display.
I want to run 1024x768 full screen, not letterboxed. Is there a way to do this? I suspect a problem with the drivers.
