Regarding the video weirdness:
- What are the makes/models of the two monitors?
- If the same monitors worked normally under Mojave, has anything changed in the frame buffer settings located here:
- Clover Configurator --> Devices --> Properties --> PciRoot(0x0)/Pci(0x2,0x0)
The monitors are an HP ZR22w connected using USB-C to DP cable and a cheap AOC g2260Vwq6 connected via HDMI. Both were working with no problems in Mojave.
Under PciRoot(0x0)/Pci(0x2,0x0) I have the settings from the guide under "Spoiler: Inject Audio Layout 16 and Enable On-Board HDMI Port"
I've tried -raddvi and it changes nothing (I can therefore suspect that either shikigva=60 or lack of DropTables MATS was causing the kernel panics I had earlier?)
Still haven't managed to get to the bottom of it - everything works great with just the HP monitor plugged in but I'm now unable to make anything work with the HDMI port from the UHD 630. Hot-plugging the HDMI makes strange things happen - sometimes flickering (black lines) other times I loose both monitors or sometimes the HP/USB-C monitor just stays working and nothing on the HDMI...
