You need to unset MONITOR_OVERRIDE after you're done with it, i.e.:

	unset env(MONITOR_OVERRIDE)

Either of those should work.

You can set and unset env(MONITOR_OVERRIDE) while the gism monitor is
running. It only needs to be set while running d.* commands which are
supposed to use a specific monitor.
