OpenCore Desktop Skylake iGPU DisplayPort Not Working

Hello!

I have managed to install Big Sur with OpenCore. (I tried multiple OS X versions, with the same results)

This issue happens before installation though (as well as after). After the boot picker, the kernel runs, spits out text and eventually my display will go blank and lose signal.

I'm using integrated graphics, no dGPU. My motherboard (see bottom of post for specs) has both a DisplayPort and a DVI port.

I tried a DVI monitor and I was able to completely get to the Apple logo and follow the install procedure, but my DP monitor refuses to show anything. I tried running both monitors and I noticed my DP monitor goes blank a little before the Apple logo shows, while text is still being printed. (I'm guessing from the kernel)

I did look into iGPU patching through WhateverGreen and I did try patching the connector-types to DP, but that didn't seem to do anything. I got a little lost when reading about bus ID patching, so I haven't tried that yet.

My instinct is that if the display is cutting out before it gets to the Apple logo, that maybe there's some sort of funky patch happening with Lilu or WhateverGreen that's triggering the display to cut out? I honestly don't know.

If somebody has an idea, I'd appreciate any insight. If you need anything else like my config.plist, let me know, otherwise I appreciate any help.

Thank you!
