   Thank you very much. Must have missed that option. Will try it when I get home.

	I've been using it with a Radeon Pro WX 4100 GPU in the small PCIe 3.0 x4 slot. Go to BIOS -> Advanced -> Chipset and change the Onboard VGA setting from Auto to Enabled, this way at least the dGPU won't disable the onboard VGA. If this doesn't help you might also try chsnging the boot mode to UEFI only with CSM disabled, if possible. Changing these two options lets me use both GPUs, at least in Windows 10, don't know about other operating systems. I quite like the X470D4U's theoretical hardware capabilities but the BIOS and BMC software state is unfortunately a mess (compare large Level1Techs thread where various X470D4U users help each other out since ASRock Rack's support is a "little bit" "understaffed" regarding this motherboard model)

	As soon as I add a graphics card to the X470D4U it is automatically selected as "primary video adaptor" and the remote KVM no longer gets a signal. The option is in the BIOS under "AMD PBS", but it can not be selected or changed. It looks like aspeed BMC GPU is automatically disabled. Does anyone know a way to bring it back and set it as primary? Other mainboards allow to select the primary graphics in this case so the remote kvm is still usable and the OS can handle both (or all) graphics cards. Without the KVM I could have bought a much cheaper board.
