I have an MSI B550 PRO-VDH paired with a Ryzen 5900X CPU (no integrated GPU) and a dedicated GPU (RTX 3080). When I tried upgrading to Windows 11, I found out TPM 2.0 is disabled in the UEFI firmware settings; in order to enable the TPM, I rebooted into Windows Advanced boot, selected Reboot into UEFI Settings option, but I just can't get a video image.

I have tried almost every cable combination available on the MB:

  • Motherboard: HDMI and DP
  • RTX Card: HDMI and DP

Is it possible to access UEFI settings using the discrete (and only) video card?

The only setting I'm missing is using the VGA adapter on the motherboard and I may be able to get a VGA monitor, however I just wanted to know if trying the VGA adapter on the motherboard would work.

Ok, afrer a while I found out the issue.

I'm using an Odyssey G9 monitor and it has the option to "lock" the Refresh Rate. In my case it was set up to 240Hz which made my screen look black as default UEFI interface refresh rate was 60Hz.

I switched the Display Port 1.4 Cable for an old HDMI 2.0 and connected it directly to the RTX Card, which made the monitor lower the Refresh Rate to 60 Hz and boom! I was able to access the UEFI settings!
