Of course I understand you! I mean, you should first set the resolution to 1920x1080 and then play with settings. You could also try this: turn off the PC, unplug the hdmi cable from both PC and the monitor, then turn the PC on and wait for it to boot (you'll know from the sound). Then, plug the cable back in to both monitor and PC. The resolution will not be correct, so go to settings and set it to correct one. Might fix it.
