Unfortunately, the int. 4k display remains black.
With an ext. monitor everything runs fine.
Do you have a tip for me?

In the meantime I have tried all AAPL,ig-platform-id's for this CPU.
With and without:
AAPL00,overwrite-no-connect string.
SMBIOS MBP 13,3 / MBP 13,1
framebuffer-fbmem
framebuffer-stolenmem
boot arg igfxonln=1 / -igfxmlr / agdpmod=pikera / gdpmod=vit9696

Is there still a chance to get the 4k monitor running?

[lametta17]

I give up.
have tried (all) possibilities.
i donate 50$ for the following configuration:
4k int. works
HDMI ext. works
Based on OC 070 or newer
Maybe someone can remotely achieve this goal.
 

[lametta17]

Now it has finally worked.
see attachment.
Thank you very much for your active support.

@lametta17 Hi !! I know this is a stretch but can you please tell me if you remember of course how did you solve this issue, I am experiencing the same problem right now but I can't seem to find a solution no matter what I try. I have your exact hardware and the exact problem black screen on the built in display but external monitor is working like a charm. thank you in advance

Try with -igfxmlr and -igfxmpc

Thanks for the reply, I will try it right now. Should I use both args at the same time or one at a time??
