This ASUS main board does support Ryzen CPUs with integrated
graphics if the BIOS is recent enough.

That's why it has HDMI/DVI/VGA connectors on the back.

Does your CPU have G or GE as part of its name?  Then it has
integrated graphics and you should NOT be using a separate
graphics card.

I have one of these boards with a Ryzen 5 WITHOUT integrated
graphics so I do use a (NVIDIA) graphics card.
