Does this SSDT also work with RX570? @mattystonnie

Yes, it should work.

Following the instructions in the first post I only get black screen in both HDMI or DVI. The only way I can get video is by injecting in Clover using Orinoco as the Framebuffer. But the problem is that, by doing so, I have no hardware acceleration (as Videoproc tells me).

Attached is my actual EFI.

If anyone could help me in that regard, that would be awesome.

Thanks a lot

Try this EFI. Also try sleep/wake cycle for acceleration if dual monitor is connected. As for dgpu encode/decode use SMBIOS iMacPro 1,1
