Bob.  The nice people at Viewsonic's tech support finally responded
about your "burn-in" problem.  They pointed me to a link on their
website which states:

Unlike CRT monitors, image persistence or "Burn-In" is not permanent on
your LCD panel. To recover from "Burn-In", leave the panel OFF for an
extended time. We recommend the use of a screen saver when the ViewPanel
is not in use.

I hope this helps.
