Hi, I installed my new LCD panel AOC F22 yesterday. After installing all the drivers it showed the resolution as 1920x1080 perfectly (DVI). Now after this now whenever i'm restarting my system everytime it goes back to 640x480 resolution and everytime i 've to select the 1920x1080 resoltuion. I've re-installed all the drivers (of Mobo as well as monitor) twice but the same problem is coming. I cant understand what the problem is. Please help me out!!!
