Re: solved this in my case:

You said:

My monitiors where both connected with a displayport cable.
A closer look at my portrep. learned me that i also have on HDMI connector.
So now i have one on DP and one on HDMI.
Both screens are now working fine.

My configuration is a one external monitor on my mid-2012 MBP's Mini DisplayPort connector, and another on the DVI connector on a USB 3.0 DisplayLink adapter.

I tried using the 5.1 drivers. No difference in result vs the 5.2 drivers: The monitor on the DisplayLink adapter is black, except for being able to see the cursor. The system knows it's there. Permissions for Accessibility and Screen Recording appear to be set correctly. But no joy.

Any other ideas?
