CPU (Coffee Lake Refresh, it is configured as Coffee Lake) with Intel UHD Graphics 630: PCI path is PciRoot(0x0)/Pci(0x2,0x0) My PC has a Z390 Aorus Elite board with an Intel 9th gen. Intel processor generation, different Intel generations have different iGPU IGPU setting depends on 2 factors: Motherboard because manufacturer can put 1, 2 or 3 HDMI connectors for the iGPU on the back pannel When this happens, we must configure the iGPU as headless mode (it is so called when it is enabled but no cable to monitor) so that the dGPU acts as main card but the iGPU is available for encoding / decoding video. When building a Hackintosh with both types of GPU we can find that, if the iGPU is not properly installed, video encoding can fail. Macs with an integrated graphics card (iGPU) and a dedicated one (dGPU) use the iGPU for video encoding and decoding tasks.
