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

[Barras]

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?

MB: Asus rog strix z390-f gaming

RAM: Corsair Vengeance LPX DDR4 3200MHz
SSD: Corsair Force Series MP510 960GB M.2
PSU: Corsair RM850x
Monitor: Benq EX3501R

This is funny, basically the exact same problem I just went through on my Asus board except I'm on an AMD Ryzen build. What I did yesterday that seems to have worked so far is enable UEFI secure boot in bios (if you can get in) and most importantly, update the Nvidia display port firmware.

Thanks! Updating the firmware for the displayport of the GPU solved it
