<< Solved >> Help! hd4600 on big sur

[Jazzy Jay]

Hey all!

I have a old pc that I used to run High Sierra on using clover. I had 2560x1440 working without problems with the exact same hardware.



So now on Big Sur 11.5 using opencore I only get 1920x1080. I tried to come to a conclusion as to why but I can't find out what the cause is, and I've spent hours on this. Tried changing the platform id to ones I found using Hackintool but just ended up not booting. Read through the guides and also tried to make sense out of Whatevergreens documentation.

I also read somewhere that hdmi only supports up to 1080 but how come it worked on high sierra then?

Heres my hw:

motherboard: Gigabyte Z87X-D3H with hd4600 gfx. Shows up as Iris Pro 1536 MB in "about this mac".

cpu: Intel Core i7-4770K

Monitor: LG 27'' UHD 27UL850 3840x2160

Thanks for any suggestions!
