Primary display does not come on, but secondary does.

So I just bought a dell E2414h monitor from a thrift store. It was in perfect condition, nothing wrong with it. I then come home, and plug it in; only the E2414H display comes on.

 

My primary monitor is the Dell P2414h, while obviously the secondary is the E2414h. 

 

I had to recently buy a VGA to HDMI adapter because DVI was going to be hard to find. Right now on my GPU, I have displayport plugged in for my P24, while I have the HDMI plugged in for my E24.

I tried to open display settings and radeon settings, and they won't open at all. I even tried restarting, and settings will not open even if I wait or restart my computer.

 

edit: I also cannot hear audio on the E24.

Unplug the Dell. Does the other come on then?

Start it up with one monitor and plug the other one in after it's running

I tried that, and the E24 came back on and the P24 went back to being off.

DDU? and reinstall my GPU drivers?

Maybe try restarting your computer, then try opening the settings.

have you checked the display settings to use two monitors?
