I just recently created a Monterey OS boot thru OpenCore, and it went smooth. The only problem is my RX580 is not showing any video signal. I am now stuck to using the stock Radeon HD5770, just to see the screen. The system information is reading that I have an RX580, but no Kext Loaded. Anything I'm missing? Do I need to install some driver updates? please help. Really wanna upgrade to Monterey now.

BTW, I still have my perfectly running High Sierra SSD boot drive and my RX580 works just fine.

you should not use two different GPUs in the same machine.

If it was just for debugging: Turn on Screen Sharing and go remotely. It's slow without a working GPU but better than nothing.
