I tried updating my 570 to the latest drivers and the DisplayPort is no longer working/detecting the monitor its connected to. My HDMI port is working just fine. The monitors and cables work just fine, and my computer will occasionally detect the monitor but still won't display anything and only shows up as a 640x480 monitor. I've already installed drivers, rolled back drivers, ran the AMD cleanup tool, Ran DDU. Removed my GPU and placed it back in. Is there anything else I can try?
