One Display black screen after sleep

Hello everyone,

for quite some time i have been experiencing a couple of problems with my hackintosh running 11.1, namely that one of the two displays i have connected (ASUS MG279Q) is not waking up properly after my hack has been sleeping, it shows that there is a signal, but the screen remains black. The other screen does wake, but starts flickering after the asus monitor has woken up. I can "fix" it sometimes by changing the display settings from scaled (1440p 144Hz) to default, and back, but this only works like 90% of the time and is quite annoying. This has also been a Problem on catalina, and i haven't found a way to fix it yet. Maybe someone else was experiencing similar problems and can help me out.

Also, the Asus monitor sometimes shows a flickering white bar (~10cm long) from the right edge, just where the menu bar is. This only happens sporadically, and doesn't affect the monitor in any other way. The other monitor works just fine and shows no flickering.

Both of those problems have never appeared while using windows, so this leads me to believe that this is a problem related to macos.

My System:

i9 10850k

MSI Z490 Tomahawk,

32GB G.Skill Aegis Memory, 3200MHz

MSI Vega 56 Air Boost OC

Samsung 970 Evo NVME

Kexts i'm currently using:

IntelMausi

Lilu

NVMEFix

SMCProcessor

SMCSuperIO

Custom USB Map Kext

VirtualSMC

Whatevergreen (Boot Args: keepsyms=1 debug=0x100 -v -igfxmpc)

Running OpenCore 0.6.4

The whole system has been configured according to the Dortania Guide, as an iMac 20,2.

I have read through the Whatevergreen Manual, but wasn't able to find anything that could be related

If anyone could help me out i would be very thankful.
