Hi,

I have been bashing my head around this for about a week now and I am running out of ideas :(

Got my hack on latest Mojave (10.14.6).

Everything works just fine on HDMI, sleep and wake without any problems. However as soon as I connect one of the monitors to DP, then computer freezes with No Signal message on all monitors.

I need to use DP as one of the monitors is a 4k display with only HDMI 1.4 and DP 1.2

I have tried the following:
- Lilu + Whatevergreen included or not
- Kext Patch in Clover -> AppleGraphicsDevicePolicy
- Inject ATI + Framebuffer Orinoco (also tried with Product ID 0x067DF and VendorID 0x1102) + Video Ports to 5
- Inject Intel with ig-platform-id set to 0x19120000 and Devices > IntelGFX set to 0x19128086
- Radeon DeInit on and off
- SMBIOS 14,2 AND 17,1
- Disabled CSM and put PEG as first in BIOS, Multi Monitor to Yes

Does anyone have any tips on what I could try next?

I am attaching my current config.plist, maybe that will help somehow.

Specs:

i7 6700K
Asus Maximus Hero VIII
16GB DDR4 Ram
Sapphire RX 580 4GB Nitro+
