I found the reason for the incorrect display of graphics. The problem was the missing setting in the BIOS - Initial Display Output with the CSM turned off. I turned on CSM, changed Initial Display Output to IGFX, and turned off CSM. Graphics are initialized correctly through 07009B3E...

I tried. Graphics are output through an external video card. In IOREG, I can see that igpu has loaded.

But after all, I need to display the image through igpu and hdmi / type-c on the rear panel :)

With this EFI the system started up. The video is output through an external video card.

I tried, the GPU was not initialized.

I tried with given settings Video does not start

Could you please send me AppleIntelCFLGraphicsFramebuffer.kext from S/L/E?

I tried. The driver did not load

Middleman, I cannot understand. 0000C598 or 0000C59B (or 000098C5 or 00009BC5?) should I specify for AAPL, ig-platform-id? Regarding the reverse-byte-order, if you flip 0000C598, you should get 98C50000. Or I misunderstood?

With framebuffer 030098C5 the igpu not initialized. There is no signal on all video outputs and there were no igpu lines in the download log

I also noticed such a strange thing. Intel power gadget does not display information about GPU power. Also, the GPU frequency reaches (according to the gadget) 5.37GHZ

I tried changing the model to imac20,1 - it didn't help. I also tried removing everything from deviceproperties - it didn't help.

Here is my ioreg. Received after removing the section from device properties and connecting the display to the type -c port (since without the connector patch, the hdmi output does not work at all)

While looking for the problem, I found your assembly repeatedly. The fact is that I do not use any patches / injections of CPUID1Data and device-id for my devices. Maybe I misunderstood you, but I cannot find the information in the WEG guide for framebuffer 030098C5, where did you find this...

Yes, I disabled the 3090 via ssdt. I am connecting the monitor to HDMI on the motherboard backplate. When you connect a display already on a running system to the type-c ports in ioreg, nothing changes, display-0 remains only on the hdmi port (index 03, busid 04). Today I tried to start mac...

Yes, I tried this framebuffer. I have also tried all framebuffers for my graphics according to the WEG guide

Good day! I ask for help in enabling the video ports of my hackintosh. Cpu 10900K MB Z490 Aorus Xtreme BOOTLOADER OpenCore Framebuffer 07009B3E macOS Big Sur iMac20,2 Can't get the HDMI and Type-C ports on my motherboard to work for image output. The image is but pixelated, buggy on two ports...
