You're a great detective, Laz 2! Yes, it is LCD. No, it's not exactly that model, because it is about 14" on the diagonal (12" horizontal); but the physical appearance is otherwise identical (even the shape of the stand), so I'm guessing it is a smaller version of the E173FP, which means the User Guide you suggest will almost certainly be relevant. (There may even be such a thing as the E143!).
I'm too busy to experiment for the moment (got to retrieve the monitor from the attic!) but I'll report back as soon as I've bottomed this out.
Thanks again for a rapid and helpful response.
