i9-10900| Msi Z490-A | HDMI Connected Screen Magenta Color Issue

[yfy]

Hi
My system specification is: i9-10900 CPU, Intel 630 GPU, and MSI-Z490-A motherboard

I set up Mac OS Catalina 15.5.5 to my system with OpenCore 0.5.9 and everything working well except for my second screen. I can get a clear vision with my display port. I made Framebuffer settings and tried some different patched lilu.kext and whatevergreen.kext files and I can accomplish get display through HDMI but the display is magenta color. How can I fix it?

I just read about this. It's mentioned (with a solution) here:

Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

Look at config-AMD-GPU.plist from the ZIP file in Post #1 and replace your PciRoot(0,0)/Pci(0x2,0x0) with the version in that file. This sets ig-platform-id to headless mode (0x3E980003 in reverse byte order). Latest version of WhateverGreen is required. got it work like this, im not so sure if...

It's also the top of the Troubleshooting section of that same thread.
