If with 'narrow' you refer to the pictures breadth, then two things
may have happended
- the deflection current is smaller
- the anode high voltage of the cathode-ray-tube is higher.
The cause for both deviations will have to be found in the innards
of the device. Often it is just a failed capacitor, but which one?

Is a narrowing screen something that typically happens when an old CRT
monitor is dying?

This may happen with a new device as well. You can usually not
assume that all parts in a device age with the same speed or start
with the same health.

Is it time to get rid of this monitor?

You will have to decide this on the basis of your preferences and
your economics. If you find a freak who likes to repair monitors, you
may well regain at low cost a device that serves you another 15 years.

Some of us who repair monitors to help keep them out of landfills for
a little longer really do not like to be called "freaks".
