I have a 9700K on top of Asus Z390A motherboard. It is running macOS Monterey 12.4. I removed my 5700XT over the weekend and sold it. It was time to use iGPU.

I plugged my HDMI to the motherboard but it gave a black screen post-Apple logo.

I removed the framebuffer patch for 5700XT and added a patch for iGPU (I didn't think 630 iGPU needed patching. I was under the impression that it is natively supported.)

Here is what patch looks like

Intel UHD 630 Patch

Here it is in text format

It is copied directly from: https://www.tonymacx86.com/threads/guide-general-framebuffer-patching-guide-hdmi-black-screen-problem.269149/ from the spoiler section at the bottom of the post. It has one pre-built for Z390A.

Here are my boot arguments: keepsyms=1 debug=0x100 alcid=11 igfxonln=1

There are two issues:

1. I use a monitor with 3840x1200 resolution.

Monitor

Intel UHD 630 properly detected

It still doesn't show the full resolution in display settings:

​

Only shows up to 3200 x 1000 instead of 3840x1200

I can select 3840x1200 using switchResX and it works fine. Why wouldn't display settings how it?

1. And the bigger problem: I get a Kernel panic post login. Usually about 15-20 minute mark. This never used to happen.

following kernel extensions in backtrace:
