I need to fix this display problem at work and can't find similar problems on google or a root cause.
Basically, this computer has 3 exactly similar monitors plugged on the card's DP ports. 2 of them work correctly, but the third shows up as a Generic Non-PnP Monitor for Windows, and as nameless for Radeon Pro settings. Of course there is some basic display, but it's stuck at the basic 640x480 resolution which only allows me to confirm the monitor detection from both Radeon settings and Windows display settings.
Here's some screenshots of the situation. Any help would be greatly appreciated.
