@pastrychef thanks. not sure, but with 18,3 I boot to blank screens.
That's the reason why I use a Board-ID from iMac 14,2 SMBIOS to eliminate the black screen. But when I enable IGPU in BIOS it takes ages to load macOS in Clover. To make ik as fast as without IGPU I did enable --disablegfxfirmware in Boot section of Clover. I didn't have had any issues with that until today.@pastrychef thanks. not sure, but with 18,3 I boot to blank screens.

When I run without WhateverGreen with my Vega 56, only one DisplayPort and the HDMI port are active. Two DisplayPorts are inactive. If you have your monitor connected to one of the disabled DisplayPorts, you will have black screen.
@pastrychef, fortunately with the RX580 I've never had a problem with 2xDP. I will caveats that on 18,3 I do have to change the board ID.
Why do you rename GFX0 to IGPU and than PEGP to GFX0 ?I should clarify that when I do use WhateverGreen, all video output ports on my Vega are active.

I did check my configuration and found out that GFX0@2 is Intel HD Graphics CFL CRB and PEG0@1 is my Radeon RX 570.
Also H264 and HEVC is working fine. But it does only show the Intel HD Graphics adapter on Top.
Should I patch (rename) too?
