I recently bought a 42 inch plasma that is full 1920x1080 HD. My 19 inch pc monitor only goes to 1280x1024 and as i have a radeon 4850 i thought that this resolution was a bit low end for this card. So i hooked it up via VGA (through a DVI-VGA connector first) and tried to play CoD MW2 on 1920x1080 but the screen just went black and reverted to 1024x768. It would only go up to 1280x1024 and i have no idea why. Any suggestions on why it would do this?
