Hello,

I recently built a system with the below specs. I'm hoping to use 2 monitors - one attached to the GPU and one using the onboard graphics via the CPU.

In my previous ASrock MB, I was able to turn on the IGPU option in the Chipset configuration, but as far as I understand that is not longer a supported config option.

What I've tried so far in BIOS:
- Advanced -> AMD CBS -> NBIO Common Options -> GFX Configuration -> Changed: UMA_AUto to UMA_Specified & UMA Buffer Size: 2GB (neither configuration worked)

Thanks for any help on this one.

Specs:
MB: B650E Taichi
CPU: Ryzen 7800X3D
GPU: EVGA 3080ti
BIOS version: 1.20.AS01

Monitors
Both 1920 x 1080
Monitor 1: Display port to GPU
Monitor 2: HDMI to CPU

For anyone having this same issue, after contacting support, it turns out it was as simple as setting my onboard video as the primary in the BIOS settings. Problem solved!
