Updated CPU/Mobo and now dGPU displayport doesn't work

Let me start of by saying I know that Z590 isn't supported and if that means no one can help, that's okay. I knew the risks going in.

I upgraded to a Gigabyte Z590 Vision D motherboard with an i7 11700k. I used this guide for making my EFI folder: https://github.com/SchmockLord/Gigabyte-Z590i-Vision-D-11900k (I have also tried iMac18,3 as that's the SMBIOS I had before when the dGPU worked)

Once the upgrade was done and I booted successfully, I found out that my dGPU displayport wasn't working and I also can't get HDMI audio.


Specs:

  • Gigabyte Vision D Z590
  • i7 11700k
  • EVGA GTX 760 2 GB

Issues:

  • Displayport doesn't work at all. The monitor doesn't even recognize the cable's plugged in
  • HDMI audio isn't working
