[Success] - Asus ROG Strix Z490-E Gaming + i9 10900K + OpenCore

hmm, i thought you’re early consultant to the effort on the ProArt thread ...

Best guess, if it has the same I225-V, is it's PCI-E address is different. You can edit the contents of the FakePCIID kext that's specific to the Intel. You can find the correct value in Windows or with IORegistryExplorer.

How did you guys get multiple monitors working?

How did you guys get multiple monitors working?

That ended up being fixed with updates to WhateverGreen. If you use my EFI, multiple monitors works out of the box with the iGPU with this motherboard.

With that said, with my setup. I leave the HDMI monitor off until I see the desktop on the DP monitor, then I turn it on. I suspect it's because my HDMI monitor is 1440p, so I'm pushing the iGPU pretty hard. Switching inputs can also accomplish the same thing.

What about multiple monitors on the AMD GPU?

That also works. I currently have my RX 560 back in the lower PCI-E slot. Same EFI.

Looks like:

RX 560 - HDMI to 1440p Dell, DP to Asus 1080p RTX 2080 Ti - DP to 1440p Dell, HDMI to Asus 1080p


The Dell is 1440p HDR with up to 166 Hz, so I give it the DP under Windows to take advantage / game.

I did it this way so I'd stop plugging / unplugging cables all the time. Now I just switch monitor inputs to boot to Win 10 or Catalina.

I got it working. It just required rebooting the computer.

The opencore picker doesn't auto select the Mac OS partition anymore after the default time has passed. Anyone know how to fix this?

Hold Control + hit Enter with macOS partition selected, it should "store" it. Also you can use the official Startup Disk application. (as long as you have your nvram setup correctly)

As always: thank you very much for the effort!

It works, I just receive at the boot an error: "failed to calculate..." - it is too fast and I cannot see what exactly.

under UEFI then audio then playchime change bolean to string and make it auto instead of false

Just had to come here to say thank you for the guide. I took my time, followed your steps here and the OpenCore steps, and only had to build once.

Everything is running smoothly as of now!
