Question ASRock motherboard unable to run onboard GPU with added GPU

Aug 29, 2019
I am working on an ASRock FM2A68M-DG3+ motherboard with an AMD A8-6500 APU with Radeon HD Graphics.

I have a Radeon RX 480 8GB gpu installed.

I appear to be able to run either the onboard GPU "or" the RX 480, but I can find no way to run the two simultaneously.

Is anyone familiar with the BIOS settings and could walk through them? I have done everything I can think of to auto enable both the onboard GPU and the added RX 480, but I am unable to solve the issue. Is this one of those motherboards that is unable to run both, so far I can find little to no information on whether it is even possible to run both with this MOBO.

The onboard GPU is a reasonably decent GPU but not in the same class as the RX 480, but it will still be a useful second and potentially third monitor for when I am programming and modding leaving the RX 480 open for rendering duties.
