Nothing has changed.
After waking up, the monitor remains black.

Hello Baio77,

I have tested your configuration.
Audio via HDMI is working. Great thanks.

After turning off the screen (per macOS via active corners) and out of sleep mode, the HDMI screen remains black.

I have additionally connected a monitor to the DP and rebooted. There is only a signal on the DP, HDMI remains dark.
Sleep mode behaves the same as with HDMI.

Looks good, will test it tonight.
Thanks a lot first of all. Will report tomorrow.

Nothing has changed.
No coming back from sleep mode.
No audio via HDMI

When the NUC is woken up from sleep mode and I enter the password on the black screen a short time later, the NUC remains active.
Keystrokes or mouse clicks do not change the black screen.
Only when I shut down the NUC with CTRL+CMD+ALT+ on/off, the text appears.

OK, Here is my EFI 0.7.4

and the new ioreg file

thanks for the link, but google forbids the download.

 

Hello Baio77,
thank you very much for your tip.
Here is my EFI

EFI.zip

Followed your tips. But it does not work.

 

The sleep mode also causes problems.
When I activate sleep mode, the power LED changes from steady blue to blinking orange. This is how it is supposed to be.
If I press a key the LED turns blue again, but there is no picture on the monitor. Hackintool shows:
hibernatemode and proximitywake green.

 

Wuz.ioreg.zip config.plist.zip

I took your advice and made the changes. After that I tried the 3 framebuffer variants.
Everything runs but no sound over HDMI.

Unfortunately, I have not managed to output the sound via HDMI.
Could you help me there again. I have already uploaded the ioreg.

Thanks for the support.
Here now the ioreg from my NUC.

Hervé gave me the tip:

 

HDMI audio can only work if you inject the HDMI type to the relevant connector (usually con1):

 

framebuffer-con1-enable 1 NUMBER

framebuffer-con1-type 00080000 DATA

 

 

But doesn't work

Thanks, all Ports are running.

What can I do with sound over HDMI?

Hello people,

i installed Big Sur with the following EFI on the NUC.

https://github.com/AndroidOL/NUC6i3SYK

 

Updated the kexts and disabled the ones I no longer need (shiki, etc).

Unfortunately, the front USB ports do not work.
Is there a possibility to enable them?

have already tried hackintools. Sticks inserted in front are not displayed.

 

Audio only works via jack, but not via HDMI or DP

Is there still a possibility to use Thunderbolt?

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

config.plist.zip

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.
 

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?

Got the following tips from Hervé:
Try and:
remove those FakePCIID kexts, they're all mostly deprecated now and should no longer required
add igfxonln=1 boot arg
change SKL framebuffer to recommended layout to 0x19160000 rather than 0x191b000
inject your EDID hex chain as an iGPU property.
switch to MPB13,1 SMBIOS, a dual-core/HD540 model, rather than MPB13,3 which is a quad-core/dual-GPU (HD530+AMD Radeon Pro 450)

 

 

Unfortunately, only the int. display runs choppy

 

(You have helped me many times now, would like to show my appreciation. How can I donate to you?)

Hello Hervé,

after disabling the FakePCIID kexts and nvreset, there is only the ext. monitor.

Thanks,

but int. display be black again.

Hello Broxteck,

when I start with the ext. monitor {Fn}+{F8}, then I get the apple (I never had until now).
Just before switching on the apple I still see the message:
Probing ...
Starting ...

When I start with the int. monitor, with the ext. still connected, the PC freezes.
The ext. monitor stays dark and on the int. monitor is the message:
IGPU setting ...

maybe it helps

Precision 5510 4k.ioreg

with or without, same result. Black screen.
