Minimizing Remote Video Session Discoloration
When establishing remote video sessions, pixel discolorations may occur due to network
conditions. This condition occurs most often with a solid color background. This condition is
minimized by using a black background. If a color background is used, a small number of pixels
on the screen will be discolored or white.
1 In the Viewer click Manual Video Adjust.
2 Incrementally, adjust the contrast and brightness until the image quality improves.
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. You should select a solid color
display background via the operating system for optimal display quality and performance.
Improving Mouse Performance
If you are experiencing slow mouse response during a remote video session, you may want
to deactivate the mouse acceleration in the operating system of the target server.

The adjustments will display immediately in the Viewer window.
A noise threshold setting is also available under Tools > Manual Video Adjust for fine
incremental adjustments.
NOTE:
Reducing the noise threshold to zero causes constant video refresh, high network usage and
a flickering video. You should set the noise threshold to the highest level that allows efficient system
performance, while still being able to recover pixel colors over which the mouse cursor travels.
