Dear friend, I spent more than 3 weeks trying to get video output on a friend's PC with the same motherboard and CPU as you but I did not succeed, al last he bought a dGPU.
I hope someone more expert than me can help you.

thank you very much for your advice. we are going to change those setting. and maybe try to understand (not sure to be honest at this point)

 

he will use only one HDMI.

So your iGPU property injection should look like:


AAPL,ig-platform-id         07009B3E    DATA
enable-hdmi20               01000000    DATA
framebuffer-patch-enable    01000000    DATA
framebuffer-stolenmem       00003001    DATA
framebuffer-fbmem           00009000    DATA
framebuffer-con0-enable     01000000    DATA
framebuffer-con0-type       00080000    DATA
framebuffer-con1-enable     01000000    DATA
framebuffer-con1-type       00080000    DATA
framebuffer-con2-enable     01000000    DATA
framebuffer-con2-type       00080000    DATA

Clear and detailed instructions that have left me speechless.

Congratulations for this text.

get rid of device-id property; iGPU id 3E91 of i3-8100 CPU is natively supported.

 

what do you mean exactly at the bottom you write

With layout 3E9B0007, you should also use SMBIOS iMac19,2 rather than iMac19,1 which is usually associated with layout 3E980003.

sorry i'm certainly stupide to ask, but it's not clear for me.

 

I just noticed that you took that line out, was that correct?


device-id 9B3E0000 DATA 

is it what i was supposed to understand by getride device-id ?

thank you for the explanation, 

my question was indeed badly put. I understand your answer. and the meaning behind ...

 

what was not clear to me is the proximity of the terms: device-id property/ id 3E91 / layout 3E9B0007 /layout-id

and the initial presence of 

device-id 9B3E0000 DATA 

while it was written get rid off device id.

I'll look at the definitions of all that words. to learn.
have a good day and thank you for your help.
