Specific configuration:
CPU i5 9500t
16GB memory
Rx5604g has only one DP output
Cannot change to imac19.1. After entering the system, the screen is black.
You can only access the desktop by screen sharing. At this time, the display has output, but it does not display the desktop, and it is not a standby posture.
It has been discussed here.
Is it possible to solve this problem by customizing the output port of the graphics card

Let's start with the attached config.plist. In it, I have changed the following:
  • AAPL,ig-platform-id = <0300923E>
  • boot-args: added agdpmod=vit9696
  • PlatformInfo > Generic > ProcessorType = 0
Please test with this attached config.plist and post your results. If it does not work, please post your results along with your revised EFI and IORegistryExplorer 2.1 output.

With each iteration, please upload at least your latest config.plist and ioregistry dump.

Would you be willing to switch to CLOVER r5122 and Catalina for our testing?

Follow the instructions here.

@lydahai Make sure that you configure your BIOS exactly as I have described in the PDF file attached here. The only difference for you should be that you are configuring the dGPU as your primary display. You also want to make sure that Legacy Boot is disabled.

@lydahai Be sure to use CLOVER r5122 and not another version.

Nice job! Now fix your AAPL,ig-platform-id and apply this patch. Please post your results. If not working, please post your config.plist and your ioregistry dump.

@lydahai - Also, we may need to experiment with both boot-args agdpmod=pikera and agdpmod=vit9696. I see you changed to agdpmod=pikera.

@lydahai Be sure to change the CLOVER GUI screen resolution to match the resolution of your display. It is currently set as follows:

Also - remove the darkwake boot-arg (for now).

I need to go, but will look again tomorrow. Good luck with the graphics patches. Be sure to read this entire post, since I added some stuff. I like your patience and persistence. Good work.
