NOTE: Reducing the noise threshold to zero causes constant video refresh,
high network usage, and a flickering video. Dell recommends that the noise
threshold be set to the highest level that allows efficient system performance,
while still being able to recover pixel colors over which the mouse cursor
travels.
NOTE: When adjusting the noise threshold, use the slider bar for large
adjustments and the Plus (+) and Minus (-) buttons at the ends of the slider
bar for fine-tuning.
Improving Screen Background Color Display
You may experience inconsistent color display when viewing target servers where
photographic images or color-intense gradient backgrounds have been selected.
We recommend that you select a solid color display background via the
operating system for optimal display quality and performance.
Adjusting the Mouse
The Viewer allows you to select between five different mouse cursor options, set
up mouse scaling, and resynchronize your mouse should it no longer track
properly. Dell recommends turning off the local cursor by setting the Local
Cursor option to None. This will leave only one cursor on the screen, the
remote cursor, and will simplify navigation.
