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:
 In the Viewer, click Calibrate. The Auto Video Adjust dialog box appears.
 Click the Manual Video Adjust button.
 Choose contrast or brightness.
 Adjust the contrast and brightness until the image quality improves.
 A noise threshold setting is also available and then 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. Fujitsu Siemens 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 Plus (+) and Minus (-) at
the ends of the slider bar for fine-tuning.
4.2.11 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.

Use the Plus (+) and Minus (-) buttons at the end of the slider bar to fine-adjust the
noise threshold to just above zero.
NOTE: Leaving the noise threshold at zero triggers constant video refresh, resulting in high network usage and a
flickering video. It is recommended that the noise threshold be set at the highest level that allows efficient system
performance, while still being able to recover pixel colors that the mouse cursor travels over.
NOTE: When adjusting the noise threshold, the slider bar can be used for large or very fine adjustments and the
Plus (+) and Minus (-) buttons at either end of the slider bar for small, incremental adjustments.
4.2.12 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.
Microsoft Windows XP Default Mouse Drivers:
 Select Start then select Settings and then select Control Panel.
 Double-click the Mouse icon.
 Click on the Motion tab.
 Adjust mouse speed to the exact midpoint of the slider bar.
 In the Acceleration setting, select the Off radio button.
 Click OK. Click Mouse Synchronize/Screen Refresh in Video Session Viewer to
resynchronize the mouse.
