Recently I was playing with some CRTs hooked up to my computer via a simple VGA-to-DVI-D adapter. Some monitors worked, but there were a few with weird refresh issues that would cause slowdown on eOS as the CRT kept restarting, attempting to correct itself.
On Windows, there was no slowdown persisting after I plugged my computer back into my normal ViewSonic 60hz LCD monitor via DisplayPort. eOS is having a bad time, however.
Pantheon is scaling correctly, but only seems to be refreshing about once every three seconds. I tried restarting the x-server and disconnecting and reconnecting my monitor but the issue is still persisting.
My specs are i7-6700K RX 580 16GB RAM
Any help troubleshooting would be appreciated.
