It's my first question here and I feel really bothered by this problem. I recently bought a new AOC e2343F2k 23" monitor, it supports 1920x1080 resolution and when I plugged by the first time, it worked perfectly.
I made some changes (I do not recall what), and I can no longer get full hd resolution, the best I can get is 1440x900.
I tried to install another different distros in order to check if the source problem is the os, but no success. I don't know what to do. I forced the resolution using xrandr but it also did not work, the screen resolution is expanded beyond the monitor edges and I can't see the right and left side of the desktop and the screen image quality is poor.
Any suggestions ?
