I've recently bought a new PC.
I have installed the Motherboard drivers, Graphics card drivers, and the monitor drivers.
Windows 7 Ultimate.
The monitor is 1920x1080, but in the screen resolution settings using a HDMi cable. When i try using 1920x1080 it leaves a 2 inch black edge around the screen, but fills it fine using 1600x900.
GPU im using is AMD R9 280x. The only problem with the pc is that it won't allow me to install ANY of the windows updates from errors.
Monitor is: samsung S24C300HS
