Just installed Windows 8.1 64-bit on a basic Linux box.
23" Dell S2340T display.
AMD Radeon HD 7700 series budget GPU.
The visible display doesn't reach the edges of the screen. There's a black band all around the outside edge of the screen. I installed the makers' drivers for the screen and the GPU but that hasn't helped.
Set to 1920 x 1080.
The display works perfectly with my Surface Pro and with Linux.
