[Guide] Intel Framebuffer patching using WhateverGreen

[KiKz]

Have you set DVMT to above 64Mb? You may need to set it in bios to 128 or higher.

yes i've tryed 32mb to 1024mb but problem is same

On Big Sur with OpenCore and UHD 530, I can't get dual display to work, but they work individually?? A DP and DVI monitor respectively

Hello Guys,
I am running macOS big sur on my Hackintosh,can anyone help me to get GPU acceleration over HDMI port? i have followed the guide multiple time but i am getting blank screen before the Logon screen.currently i am on HDMI but without Acceleration.
Previously i am on Mojave final build using SMBIOS mac mini8.1 , and on that everything was perfect like sleep-wake,iGPU...
So I copied platform info and GPU info for creating a Frame buffer patch but no luck.Here now i will post my both frame buffer patches screenshot for more understanding.
Please someone help me to setup System.

Spec:-
Coffee lake Core i3 8100
Asus B360 M-A Motherboard
LG 21.5" 22MK600 Full HD IPS Monitor via HDMI
SMBIOS iMAC 19,2 (Closed to my specs)
Open core 0.7.9

Thank you!!

Thanks for the File,but still it is not working,i have tested both the ports....so is there any way to copy the settings from clover config.plist to open core.plist

Specially Graphics settings

yes

the DeviceProperties.. yes

 

[Ritesh]

the DeviceProperties.. yes

So can only copying Device properties will work in my case?because some of the kernal patches are present in clover plist file like
1. change GFX0 to IGPU
2. change PEGP to GFX0

If that are not required then with clover device properties my UHD should work,i will give it a try, apart from that anyrhing need to copy for UHD acceleration?
