Finally got Mojave up and running on an old legacy 6 series board. I am now having two issues with the GPU. Firstly, two of my four ports don't properly work. I have 1 HDMI and 3 DP on an MSI RX 580 8GB board. The HDMI and the DP immediately beside it display the attached photo. Ports 3 and 4 work, but they have another issue: I am limited to a 30 Hz refresh rate. Thing is, 50 and 60 Hz are displayed, but if I click on them then the display also looks like the attached photo.
It seems especially weird because in my Sierra 10.12.6 setup all ports work and I can get (thru DP with adapter to HDMI) full 2160 x 3840 (1080p Hi Dpi) at 60 Hz and even 10 bit with Switchresx.
I've tried all sorts of things: Lilu/WEG, injecting ATI thru Clover with # of ports, device ID, Vendor ID etc, injecting VBIOS from the ROM folder etc etc. Right now I'm running a very plain vanilla config.plist with no graphics injections and the card seems to have full acceleration on ports 3 & 4 and shows up as RX 580 8192 MB in about this mac.
Anyone have any ideas on how to get all ports working/how to fix refresh rate?
