It has an odd Resolution for a Monitor.
With no video outputs do you get an error message like "Out of Range" on the Monitor?
Do you have video output when you give it time to boot into Windows?

It is possible your Monitor needs to have its Monitor's Settings or in BIOS changed.
If your BIOS is set at UEFI Mode (Due to Windows 11) see if it works if you change it to CSM Mode (Legacy Mode) in BIOS.
NOTE: Some monitors simply doesn't have video output when in UEFI mode, only when Windows starts loading do you have video output.
