I see. It's very strange that something would be failing. And to correct you, no it doesn't resolve it self. If I leave it be the monitor will go blank but it will not display "No Signal" message. I mean as soon as you replug the display port it shows up like normal. Could it be a hardware failure if i'm running the PC in 100% usage and it's not happening then? Wouldn't there be some sort of artifacts in games or stutters? Also, the other display ports haven't done this yet, only one of them has this issue. My previous card which was a 980 didn't have this problem with this monitor if that helps.
