Menu bar cut off on right of display, both with and without external monitor connected

With Mac OS Big Sur 11.0.1 (on the new 2020 Mac Air with new processor), I am experiencing a screen resolution problem.

Immediately after reboot it is OK, but after connecting to a USB-C Sony 4k TV (extension not mirror), the resolution of my primary (laptop) monitor gets reset to a value that is too big for the screen.
Connecting or reconnecting or unplugging the external monitor has no effect on the laptop screen.
I have already tried 'default for display' and the various 'scaled' options, but it appears that Big Sur annoyingly doesn't allow you access to manually setting resolutions any more.
Rebooting the Mac Air solves the resolution problem until I plug in the external monitor again.

Anything I can do?
