Graphic issues after Update to Catalina

[Ice]

Hey guys,

I just updated to Catalina (10.15.2) and am experiencing issues with my graphics card (specs in signature).
I have three monitors connected, but even though all three are being shown in the system, only the main display (DP) actually comes up. The other 2 (HDMI,DVI) just stay dark. I am also seeing some artifacts on the main display.
Prior to the update I updated Whatevergreen, Lilu and AppleALC to the latest versions. I am using Clover 5100.
Any ideas what I might have missed or could do to fix this issue?

Thanks in advance,
Ice

It looks like there's a problem with my Clover install. Booting from UniBeast with Clover 4961 all displays come up and the system runs way smoother than booting from Clover 5100.
What options do you guys choose when installing Clover 5x?
