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:

1From the Viewer menu, select Tools - Manual Video Adjust. The Manual Video Adjust dialog box appears.

2Choose contrast or brightness.

3Incrementally, adjust the contrast and brightness until the image quality improves.

4A 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.
