Good Morning. With Mojave and Catalina on my previous P55-USB3 motherboard, only the 2 DisplayPort ports far from the motherboard worked, the other DP, HDMI and DVI gave black screen.
With modifications proposed by
@foxbox (inject a patch to Orinoco framebuffer from KextsToPatch + 3 changes in Graphics section: Orinoco in FB Name / Inject ATI / 5 in Video Ports) I got the 5 ports to work well, better with Lilu and WEG. But without
@foxbox modifications, other outputs that were not those 2 DP that I have mentioned never worked.
However, with the new Z390 Aorus Elite board and Catalina or Big Sur surprisingly all 5 ports work well with Lilu and WEG (without WEG not all work) without having to do any other modifications.
If your monitor has a DP connector, the best solution is a DP to DP cable. If your monitor doesn't have DP, another solution is a DP to HDMI cable.
If you try the patch, all changes must go together:
- inject the patch to Orinoco framebuffer from KextsToPatch
- 3 changes in Graphics section of Clover: Orinoco in FB Name / Inject ATI / 5 in Video Ports
- try with and without Lilu and WEG.
