What I hadn't realised was that one can drag the two 'screens' on the
display in the application window.  By default the "Unknown" one was
right on top of the "Dell" one which is the one I needed to set up.

I sort of guessed as much but it didn't appear to do anything, until I
uncovered the Dell 'window' that is.

:-)   If there had been some help I probably wouldn't have had to ask
any questions here.
