Question [Solved] Having trouble getting into UEFI/bios

[Fanatical Meat]

I cannot get into UEFI, no splash screen and I am not sure when this stopped. I know I used to see an ASRock screen briefly.
I’ve tried pressing F2, F10, del and I think F8 all with the same result hangs at a black screen.
I’ve tried going into the recovery options and no advanced setting for UEFI/bios in windows 10
I’ve tried the boot to bios command line and it says something about it not being supported on my hardware
I’ve tried the ASRock boot to bios app which yields same result, hangs at a black screen.

what should I do?
create a recovery ubs or just keep booting to the black screen and hope windows figures out something is wrong?
something else?

ASRock x570 steel legend
AMD 3800x
Windows 10 not sure which version but it had a large(ish) update a week or two before I wanted to get into UEFI.
edit: my machine is backed up reasonably well. I am not too concerned with losing data

edit #2: to be clear the machine works fine otherwise, I can start windows normally.

hah I have the same mobo! Anyways the next step of troubleshooting id do is clear cmos at the jumper/pull the battery. Sounds like maybe at some point you turned on fast boost and maybe it somehow with the windows update its gotten bugged up? Would be very interesting if clearing cmos doesn't work, next thing I'd do after that is disconnect all drives and surely that'd make it boot into bios.

In windows, have you tried going to start menu and done a shift + restart, and then reboot into UEFI firmware settings?

I haven’t tried that but I’ve tried the thing that leads to this
Settings-security-recovery or something.

Looks like this when done but no UEFI option is present

I’ve also tried the power user thing, windows key + X command line stuff.

Didn’t think of that, I could just disconnect the drive and go to bios then look around for the slower boot thing I know will be buried in there.

Darn, just had a thought.
I took a class and set up a second an old 1024 monitor but I think I currently have windows set to use one display. I wonder if the UEFI is being displayed on the older smaller monitor that I have turned off but still connected.

Edit: This was the problem. Unplugged the now unused second monitor and saw the normal asrock splash screen and entered bios without issue.
Strange how it wanted to use a monitor that was turned off.
