So I've been running dual monitors for a long time now and in the morning i was on my PC playing games and it was fine, turned it off and later came back to it, the main display was all messed up. The resolution on both monitors was the same (1920 x 1080) but then it changed to a lower one on the other monitor. So one monitor was normal and the other was huge. Don't know how this happened, it was working fine but out of the blue.. Anyone know what could have caused this? Googled a lot, couldn't fine much.
