Hello. I am experiencing a problem with my Catalina vanilla installation.
My Dell 7567's screen is constantly blinking. This started in the installer and persisted after successful installation. Apart from the mentioned, the system is working perfectly fine.
I am able to disable the backlight completely by pressing F11/brightness down button. I am barely able to see the on-screen text using a desk lamp afterwards.
I have tried installing AppleBacklightFixup.kext, Lilu.kext and WhateverGreen.kext and setting my SMBIOS to iMac18,1 but none of those proposed solutions have helped me so far.
To illustrate the problem, I have recorded a video (link) of my laptop booting into the installer and then shutting down. I have also included my CLOVER folder.
I recently upgraded my Hackintosh Built to a Gigabyte Z490 Vision G with an i9 10850K CPU.
Everything is working fine so far using OpenCore. But I am having issues with the HDMI and DisplayPort of the iGPU. I tried several patches using Hackintool to get either HDMI to DVI Cable or DisplayPort to DVI cable to work, but every time I boot, the Monitor turns off. I don't know how to fix it. Can somebody point me in the right direction?
