I'm not sure I understand your description, but if you're programming
the shifter to take Vsync from an external source, and there is no
external source, you can actually case MORE damage to your monitor
than leaving it on.  Monochrome monitors in particular don't like
being turned on without any synch information: they make a noise
like they're in pain, if your ears can pick it up.

Here's a good chance to say NEVER LEAVE YOUR ATARI MONOCHROME MONITOR ON
(for long) AFTER TURNING OFF YOUR COMPUTER.  A minute or two is fine,
but over the course of hours something gets hot inside and eventually
your monitor dies.
