Who are the manufacturers??  I have monitors up and running all day and none
have demonstrated "etching" or "artifacts on the screen".

Check that the customer has the proper drivers installed for the monitor(s)
they're using.  If it's an "embedded" DVR that's going to be tough to do
though.  Most often there may be "compatibility" issues and a list of
approved monitors to run with the specific machine.  The problem may also be
the video card and not with the monitor itself.  You could test this
utilizing another monitor (if the customer has the manuals for the machine
make sure it's one that complies with the DVR manufacturer's "recommended"
specifications).
