I have my Acer Aspire connected up to my desktops monitor via vga. On duplicate displays my monitor is running at 1368*768 (max res of the the laptop) or something and looks horrible (its usually 1080p). When set to use extended displays the laptop registers that the monitor is 1080p and uses the full resolution however it doesnt use the full screen region ie I have a really really big black border around the small square of "screen" in the middle. Any ideas as to how I can get it to display in 1080 and use the full screen?
GPU: Radeon 6470M
