Summary: low value current drain

Color monitors often draw a little bit of current when the front
panel power switch is off.  This is due to the fact that a
de-gaussing coil is wrapped around the front edge of the CRT and
supplied with a few mA of 60Hz current to prevent a static magnetic
field from forming on the shadow mask and causing color blotches.
The AC switch is often rigged to send a larger current for a few
seconds right when the monitor is switched on to clean up any
residual field.

For these monitors, I'd leave them plugged in, but not turned on
overnight (unless somebody is around, of course!).
