Strix X670E-E Gaming Wifi not showing BIOS screen after BIOS update

[kakugo]

Yesterday I updated the BIOS to version 3112 in preparation for a memory kit upgrade, and after that, I am unable to see the BIOS screen, probably due to some DisplayPort signal issue. I have an RTX 4090 FE with the latest firmware and a Samsung G9 Neo. Changing the DP port on the video card does not help. I can still visualize the BIOS if I change the DP version from 1.4 to 1.2 in the monitor configuration, or if I connect a secondary monitor via HDMI. I never experienced this issue and it is now systematically present with BIOS 3112. Clearing the CMOS did not help. When Windows loads, everything works normally, no issue whatsoever.

Is there a possible explanation?

Thanks in advance.

Hello kakugo

Try my 3rd suggestion on page 2.

Can't get into BIOS with RTX 5090 - Page 2 - Republic of Gamers Forum - 1100772

Same behaviour on G9 OLED and ASTRAL 5090 LC. There is no bios screen until OS load. Only way to display bios screen is to keep monitor menu open.

In the thread I posted, the OP says the issue was with his monitor. Connecting another monitor he was able to access the bios.

Check for any firmware updates for your monitor.

I followed the steps suggested by Nate152, and it worked. I'm not sure why, because AFAIK it's just another way to enter the BIOS and it shouldn't be different than pressing DEL at boot, but the facts are that I never had the problem I reported again.
