My guess is that the refresh time on your video display is not fast enough
for the visual effects.  I have used some displays where you can't see the
mouse unless it is sitting still.  A simple test is to plug in the display
and move your mouse around.  If it disappears, your display is not as fast
as the screen.  This may cause your effects to not be displayed.  This all
assumes that you are getting the correct effects on the Mac screen during
your demonstration.
