Add agdpmod=pikera to your boot arguments.

The SSDTs you are using is not customised for your motherboard, if I am correct you have just downloaded the pre-built SSDTs.

How is your Graphics configuration BIOS? Primary Output Device, State of Integrated Graphics, etc ?

Connecting using HDMI

I have never been able to get HDMI working very reliably with macOS. In order to get consistent video output, I have to lower refresh rate and/or lower resolution (non-HiDPI).

Actaully it's working very stable with mavericks also with catalina with the same efi, i got this wired behavior only with big sur, the issue also happens with display port :/

If you were able to get 4K working reliably over HDMI in Mavericks and Catalina, you are way ahead of me. I would randomly get black screen on wake from sleep or random snowy image. DisplayPort has always been 100% reliable for me.

There's really nothing in your EFI that would affect video that I can see...
