@jaymonkey , just want to give a quick update on this issue. After setting the dGPU as the primary display port and the iGPU became headless, the FCPX stopped working. My PlatformID is set to Macmini8,1 so the FCPX does not expect the iGPU to be headless. I had to reenable the iGFX as the primary display port in BIOS in order to get FCPX working again (even though my only monitor is actually connected to the dGPU)
It seems that I have to change my PlatformID to iMac18,3 as suggested above, but I'm afraid FaceTime will stop working if I do that! I've already spent a long time playing with serial numbers and codes till I got it working and really don't want to do it again! So, will changing the PlatformID from Macmini8,1 to iMac18,3 affect the FaceTime operation?
Try changing your SMBIOS to iMac19,2 and creating an SSDT with ssdtPRGen to enable your BIOS overclock. It's always best to match the SMBIOS as closely as you can with your CPU, and that iMac happens to have your exact CPU albeit the unlocked version (no real Macs are overclocked, even the ones that have K-version CPUs). First you get the SMBIOS right in Clover, then you make a custom SSDT to get your BIOS overclock. When you have done these things, and disable your Intel graphics in both BIOS and Clover, I am confident you will get GPU transcoding happening in FCPX.
Disabling Intel graphics may affect Facetime or it may not. But taking the steps I listed above will get FCPX working again for you with your hardware.
