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.
To minimize remote video pixel discoloration:
1 On the client system, launch the Remote Console Switch Software.
2 From the Management screen, go to Tools - Manual Video Adjust.
3 Choose contrast or brightness.
4 Incrementally, adjust the contrast and brightness until the image quality improves.
5 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. 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.
