Used Detach on a monitor, unable to reattach in any way.

I pressed the Detach button, not realising what it was there for.

I have not been able to get the computer to even recognise that the monitor exists, let alone attach it.

What exactly does Detach do to a monitor?

What ever it does, please remove it.

Had to connect the monitor to the computer through a different display tech (HDMI as both DP ports were not working) and then factory reset the monitor.
