@digumo I don’t have an iPad which is new enough to work with Sidecar, so I can’t try it out. But as far as I have heard Sidecar doesn’t work with any T2 SMBIOS, no matter if iGPU is enabled or disabled.
So you always have to decide: Sidecar or fully working DRM? On my machine DRM is only fully working with iMacPro1,1 SMBIOS. The shiki boot arguments in iMac19,1 don’t solve the DRM problem fully. Netflix playback in Safari only works with iMacPro1,1 SMBIOS for example – at least on my machine.
I have HEVC with iGPU disabled and Vega 64 and SMBIOS is iMAC19,1If you want HEVC support with IGPU disabled, use iMacPro1,1 system definition.
The down side is that I don't know of anyone who has gotten sidecar to work on iMacPro1,1.
In my “reorganize” post I stated QuickTime playback as being okay. Rereading your original post, I see that you did mention QuickTime export so I’ll need to fix the reorganize post a second time.@CaseySJ But isn’t exporting as HEVC in QuickTime Player encoding? See screenshots.

@CaseySJ how do I check for the name? I currently have my iGPU disabled, but are the ??? the result of not having a valid SSDT? I need to learn more about those. Is it because the one in the list is starting with Vega 20 and not AMD?I'm not sure if this adds any value or not... but I'm now configured as iMac 19,1 in headless configuration. When I sweep back and forth through my FCP timeline, iStats Menu shows my RX 580's processor is pegged - no activity shows up in the "Intel UHD Graphics 630 (Mobile)" section. I guess I have the whatcha-ma-callit, SSDT?, thingie that renames the graphics card with an "AMD" preface. Is it possible the Vega cards aren't alphabetically listed first, like my SSDT-renamed AMD RX 580 is?

System Information --> PCI will state the name of your AMD GPUs. The SSDT can be removed at any time to see what happens when the alphabetical order is reversed (i.e., when "Intel UHD 630" comes before "Radeon RX 580").@CaseySJ how do I check for the name?
