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 From the Viewer menu, select Tools - Manual Video Adjust. The Manual

Video Adjust dialog box appears.

2 Choose contrast or brightness.

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

improves.

4 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 hi ghest level that allows efficient system performance, while still being able

to recover pixel colors over which the mouse cursor travels.
