Can I use onboard graphics for one monitor, and a dedicated video card for 2 others?

[kingcra]

I have 3 monitors, one linked with hdmi, one with dvi, and the last with dvi. However, I only have 1 hdmi port for my video card. Can I use onboard graphics for it, and use my video card for the others? Or is this not a possible combination.

I have the same setup, 3 monitors connected to the GPU, and 1 monitor connected to the onboard graphics. All monitors display and extends my desktop flawlessly (though with higher CPU usage due to that 1 monitor when in use).

It could work with yours, but it depends on the motherboard BIOS settings.

Try going to UEFI BIOS Utility > Advanced Menu > System Agent (SA) Configuration > Graphics Configuration.

Try to set iGPU Multi-Monitor to [Enabled] and Primary Display to [Auto] (or [PCIE] if it doesn't work).

My motherboard is Gigabyte H97 Gaming 3 and it actually worked for me out-of-the-box without me tinkering with the BIOS settings.
