Can't get into BIOS with RTX 5090

[Lude2Envy]

I can't access my BIOS with the TUF RTX 5090. I have a black screen from boot all the way to Windows sign in. I'm running BIOS 4301 on my Z690 Extreme. The Z690 and 5090 are fully updated in Armoury Crate. If I plug an HDMI cable into the MB and boot on the iGPU I can see the ROG splash screen and can enter the BIOS. I tried clearing the CMOS with no luck as well. I also tried disabling Fast Boot with no luck. Thanks.

Have the same with TUF Gaming RTX 5080.

Thanks for sharing you case. At least I can enter BIOS now switching to HDMI.

I solved my problem. The solution is in this thread.
