First, things work fine when I am using just my hi-res laptop display, or that

according to Windows 10. At present I am using a lower resolution external

(and also xlaunch?). Here are the issues:
Thanks for reporting this problem.
When booted with the external lo-res display as the main display:
- xterm windows come up with a very large font.
- The X menu (controlled by .XWinrc) does not come up.
This means that you're right-clicking on the notification area icon, but no
menu appears?
Correct.
If so, I guess this means that we're getting confused about where to place the menu, but I'm not
sure how that could happen.
wrt the font scaling issue, looking at the source, it seems that we don't re-consider the display
dpi after a WM_DISPLAYCHANGE message, but keep on using the value determined at startup. This is
probably a bug.

As a workaround, you might experiment with using the xserver option '-dpi' to set a value
corresponding to your hi-res display, so that will be used even if the normal-res display is
Windows' primary monitor.
That didn't hurt at least. I did not go to the trouble of rebooting,
but given that I had booted to the hi-res Window and then started X
with the lo-res as primary, the font scaling was right. The menu still
did not come up, though. That seems to require starting X with the
hi-res Window - the one that was primary when Windows was booted.
