Noise Settings
Detection thresholds
In some cases, noise in the video transmission keeps the packets/sec count up, which is indicated by small dots
changing in the area of the cursor when it is moved. Varying the threshold values may result in “quieter” screens
and can improve cursor tracking.
You can modify Noise Threshold and Priority Threshold values if you are using standard video compression.
You can also modify Block Noise Threshold and Pixel Noise Threshold values. You can restore default
threshold values by clicking Auto Adjust Video.
Block Noise Threshold and Pixel Noise Threshold
The Block Noise Threshold and Pixel Noise Threshold values set the minimum color levels in terms of changed
video blocks and pixels per thousand that are allowed.
• The Block Noise Threshold sets the minimum color change that occurs in a single video block. Increasing
the value reduces the network bandwidth. Decreasing the value makes the size of these artifacts smaller.
• The Pixel Noise Threshold sets the minimum color change in a single pixel. Decreasing the value reduces
the number of low-contrast artifacts, but increases network bandwidth.
See Adjusting the View on page 34 for information about changing the color depth.
Mouse Settings
Adjusting mouse options
The Video Viewer window mouse options affect cursor type, Cursor mode, scaling, alignment and resetting.
Mouse settings are device-specific; that is, they may be set differently for each device.
NOTE: If the device does not support the ability to disconnect and reconnect the mouse (almost all newer PCs do), then the mouse
will become disabled and the device will have to be rebooted.
Cursor type
The Video Viewer window offers five appearance choices for the local mouse cursor. You can also choose no
cursor or the default cursor.
In Single Cursor mode, the display of the local (second) cursor in the Video Viewer window turns off and only
the target device mouse pointer is visible. The only mouse movements that appear are those of the target device
remote cursor. Use Single Cursor mode when there is no need for a local cursor.
