I'm having trouble with my monitor not showing anything until I open the BIOS. Pressing DEL to enter BIOS doesn't work because the screen stays black. I don’t have a built-in graphic card, so I can’t use any ports or RAM or HDD. I changed the monitor, GPU, updated BIOS, removed RAM and HDD, but I still can’t get any signal during boot. The issue isn’t that I can’t enter BIOS, it’s that my monitor doesn’t receive any signal when I’m inside it. Thanks for your help!

Press the Windows button, hold Shift, click Restart. If it reaches the blue screen, choose Troubleshoot then boot to UEFI. When it restarts and enters BIOS, turn off Ultra Fast Boot.

It didn’t work because the monitor couldn’t receive any signal until Windows launched.

Change GPU port settings to test different connections.

Do you possess several screens? HDMI is the standard on many graphics cards. When a monitor connects via HDMI and another via displayport, the bios splash will appear even if the monitor is assigned to monitor 1 in Windows.

I didn't use just one monitor, I also tried different ports and other monitors.

Could it be your display trying to connect? Have you attempted to switch the source to manual?
