1080 display port not working

I just built my first pc which has the msi geforce gtx 1080 and have an AOC 35 inch g-sync curved monitor. When I turn on the the computer with the monitor on and display port connected, it displays fine. However, whenever I switch to HDMI mode on the monitor and then switch back to display port, it fails to display saying no signal. Same thing happens if I unplug and replug the cable, and also happens if computer goes into standby. Once signal is lost I can't get it back. Only time I can get it to display is if the monitor is already on before I start the pc.

My initial thought is that it is an input mode on the monitor. Switching between the Displayport and HDMI should be auto detected, but maybe not. I would check the cable initially, just to make sure the cable is not messed up and moving it isn't coincidentally causing this. I would also check the manual and the built in options to check if it is a feature.

Upon initially reading this I am wondering why you need to switch the modes? If you go into the settings of your OS and you can set it to not go to sleep/ standby. While this could be annoying it would be a fix.
