[SOLVED] Skips splash screen and unable to enter BIOS when using GPU - Asus Rog Strix z390-f gaming

Oct 7, 2019
Hi =)

Just set up my new components. Working fine, except one annoying problem.

When I connect my monitor to my GPU via DP, there is no splash/POST screen. I'm unable to enter the BIOS, no matter how much i press "del" or "F2" during boot. The computer boots directly into Windows.

If the monitor is connected to the DP port on the MB, I get into the BIOS.

It's been like this since before I changed any settings in the BIOS

What I have tried this far:
  • Change monitor settings in BIOS from iGPU to PCIe
  • Update to the newest BIOS version (1302)
Any suggestions?
