No bios display if i use HDMI cable on Rog strix x570 f

[user73]

Hi

Mobo Rog strix x570 f gaming 

Cpu x5800

Gpu 4070ti

Monitor LG 45GR95

I can get bios display if i use display port but using HDMI cable no display. It goes straight to win11.

I have already tried disabling fastboot and disabling CSM support.

Don't want to use DP in windows as Hdmi has better black level.

thx in advance.

Update-   I found out problem was that i  had connected primary HDMI port to Denon AVR for this reason it was not showing in Bios. Never knew GPU's have primary and secondary ports too. I hope  this might help someone.
