Internal screen black screen problem

[Misiac]

And it somehow worked on Monterey with Skylake ids...

Okay, I applied these patches. reset NVRAM twice. Still blackscreen with visible backlight.

What do you mean by visible backlight?

The only difference is I can't see Built-in display in Ventura settings. I could before and I was even able to control backlight level. Attaching files.

The built-in Display is only available when it detects an internal screen along with the PNLF patch active.

As per the IOReg, Framebuffer@1 is active which is the external monitor (connected via HDMI) so the internal screen is missing for sure. Add -igfxvesa in boot args and attach a copy of IOReg.

Interesting. Try to use 00001B19 as ig-platform-id and also add 16190000 as a device-id. Attach the PR Files.

The screen itself is turned on and I can even adjust brightness in settings. Attached the comparison image.

Add -igfxvesa in boot args and attach a copy of IOReg.

If I add -igfxvesa I can't find any AppleIntelFramebuffer in IOReg, so I am also attaching a IOreg copy without -igfxvesa and patches from the previous page with appropriate configs to be clearer, you can see both internal and external displays there.

Should I delete these patches since they make my internal display not being discovered at all?

It boots on internal screen, but with no acceleration and 7mb vram. EFI attached.

The second file you attached, has Internal and external monitor working but does this gives acceleration or do you see a black screen still?

IOReg is missing.

It has acceleration, I can see 1536mb vram on external monitor, internal still black screen

Also I noticed when I add "enable-backlight-registers-fix = 01000000" I can't adjust brightness anymore

IOReg is missing.

Use 00001659 as an ig-platform id and 16590000 as device-id. Reset NVRAM twice, boot and then attach the PR files including IOReg, Hackintool PCIe Report, and System Information.

Black screen on both with these.

Since 00001B59 is most stable platform-id. I am switching to it and attaching the reports.
I screenshooted them since I wasn't able to find a better way.
If you want something different, tell me.
