If your using a laptop there is a function key to send video to both the LCD
and the VGA output jack at the same time.
Function F5 on my Toshiba.
If your doing it from a desktop then you need a VGA splitter or a dual head
video card if you want to display it both onscreen and on the projector.
In all cases what you see on the monitor should be the same as whats on the
projector
If this is not what your getting at let us know.
