not sure you can have the rx set as headless, you would be better to use the rx to drive your monitors
True, it definitely is better to have the RX 580 driving the monitor, but with the LG UltraFine, this isn't possible without an expensive adapter.
I'll get the monitor and then if the performance is too poor then I'll eventually buy the adapter.

I tested the headless RX 580 and it works. Using Activity Monitor and viewing the GPU history, I can see that the GPU is utilised when exporting video in finalc ut for example, where the iGPU can't handle it all so it offloads to the RX 580, similarly to what a 15/16" MacBook Probably does.

My SMBIOS is 17,1. Sidecar even works. It's just waking up from sleep that doesn't work where the computer will just restart after failing to wake up

RX580 Headless? Cool. Can you please share your EFI?
