Thanks a million but it didn't work

After a zillion of tries, finally discovered how. I was using a DVI cable and the following patch only works with HDMI.

I use OpenCore, so needed to add some patching, which is done trough:

Device Properties
PciRoot(0x0)/Pci(0x2,0x0)
AAPL,ig-platform-id Data 00009B3E
framebuffer-con2-enable 01000000
framebuffer-con2-type 00008000 (HDMI port)
framebuffer-patch-enable 01000000

Hope this helps someone.

This worked for me. I have a bit of color issues with Safari tabs but everything else seems to work just fine.

it works like a charm, but cannot turn on screen after screen off, but turning off then turning on monitor will wake the screen up, I got this problem for 4 days then I see your comment, thank you so much

In my case I solved by upgrading Clover to the latest version.
Since I only had access to System Recovery and no other Mac, I've downloaded an ISO image of the latest Clover, put it into a USB drive and then copy to my EFI using terminal commands (diskutil list, diskutil mount, cp and mv to rename the old Clover building.
Remember to remove the third party kexts from S/L/E and copy them to kext folder at the new Clover building. Copy your custom config.plist to the new Clover building too.
Good luck!
