[SOLVED] Display 1 isn't active??

[shearari]

I have a two monitor setup and have never had problems. But for some reason only one at a time is working right now. My main monitor is plugged in using a DisplayPort, and my second monitor uses an HDMI. When my second monitor is not plugged in to the HDMI my main monitor works fine, but as soon as I plug in my second one my main monitor goes black. I went into display settings and I can see it listed but it says it is not active. Any way to fix this? I have restarted it multiple times and obviously the cord is working if the monitor comes on when my second one is not plugged in.
Any help would be greatly appreciated!

Thank you!!

Specs of pc I'm not sure if I need to give you nvidia walk through or Radeon walk through but it sounds like your display setting got set to single display enabled, disabling clone/extended monitor.
