bios How to make BIOS show display when using IGPU output

eroge69 · June 18, 2023

I'm having problems using p106 with display port on the motherboard.
BIOS considers P106 as display 1 and does not want it to appear on IGPU which reads as display 2.

There is no problem with windows display, only BIOS. I have set the default display to display 2 but it has no effect on the BIOS.

Previously I used the GT-710 as display port to set the BIOS to keep IGPU active even when using EGPU.

Is there a way to make BIOS still appear on IGPU even though EGPU is installed?

My motherboard is ECS H81H3-M4 with Intel I3-4130

BIOS behavior is going to be completely independent from Windows. You would need to modify BIOS settings to influnce pre-Windows operations.

It sounds like you already have the video output set to use both iGPU and dGPU if the iGPU acts as your extended display in Windows.

The only simple solution I can offer here is to swap the display cables if the monitors have the inputs to do so. BIOS usually doesn't offer much in ways of altering video settings but you can check under the advanced tab. See what video settings your board offers.
