4. The Video Viewer
When clicking Auto Adjust several times does not set the contrast and brightness
as desired, adjusting the contrast and brightness manually can help. Increase the
brightness. Do not go more than 10 increments before moving the contrast.
Generally, the contrast should be moved very little.

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 51 for information about changing the color
depth.

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.
