One feature of HIGHLite Displaysis the automatic creation of a new entry in the
Entry List when a new source is modified using picture controls such as 
brightness etc. If many different sources are used with the projector it is 
theoretically possible to fill the 100 entries available in the Entry List. If this
occurs, in the worst case the projector may not be able to display an image.
Therefore it is recommended that the Entry List is periodically cleared out, 
deleting any unwanted RGB signals using the Cut command in the Entry Edit
Command menu.
