Help! How do I undo monitor settings for second display?

[dmcni1]

Help! I've tried to connect a second monitor to my laptop. While trying to work out how to connect, I clicked 'second display only' in settings. As the laptop can't detect the second display, I now can't see anything( !?!)

I've tried turning laptop off in the hope it would not save and reset, but no joy - still a blank screen. Any ideas?

Windows key + p key and then tap down arrow, then enter key, repeat a couple times and main screen should come back.

It is customary to assign the "solution" to the post that contains the solution, but very glad it got worked out.
