Lilu and WhatEverGreen properly installed.There should be no cable between iGPU HDMI port and any type of display.iGPU and dGPU must be enabled in BIOS with dGPU as primary.This is important when using the iGPU as a main or single card but not when using it in headless mode. Index 3, BusID 0x04, Type HDMI (this is the active port, the only physical one, type is HDMI) Index 2, BusID 0x00, Type HDMI (type does not matter on this port) On this board there is only one HDMI v1.4 connector for the iGPU, it corresponds to index 3 in the theoretical list of 3 internal connectors this iGPU can have: Index 1, BusID 0x00, Type HDMI (type does not matter on this port) 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.
