Minimizing Mouse Trailing
During a remote video session, as the mouse moves on the screen, some pixels
will remain discolored. This condition is referred to as mouse trailing, and is
due to varying levels of network and other noise in different environments. To
minimize mouse trailing, you may need to reduce the Noise Threshold in the
Manual Video Adjust dialog box.
To reduce the Noise Threshold:
1 From the Viewer menu, select Tools - Manual Video Adjust. The Manual
Video Adjust dialog box appears.
2 Click the Noise Adjust Threshold icon for the feature you wish to adjust.
3 Using the mouse, move the slider bar to the center of the scale, and then
down to zero.
4 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 is used for large
adjustments and the Plus (+) and Minus (-) buttons at either end of the slider bar for
fine-tuning.
Improving Mouse Performance
If you are experiencing slow mouse response or if the mouse pointers get out
of sync during a remote video session, you may want to deactivate the mouse
acceleration in the operating system of the target server.
Microsoft Windows:
• Turn off mouse acceleration
• Adjust mouse speed to the exact midpoint of the slider bar.
NOTE: See the documentation included with your Windows operating system for
specific instructions.
Red Hat Linux:
1 Select the Mouse settings from the Desktop Controls.
