Color Settings
Adjusting Color Depth
The Dambrackas Video Compression
®
(DVC) algorithm enables users to adjust the number of
viewable colors in a remote session window. You can choose to display more colors for the
best fidelity or fewer colors to reduce the volume of data transferred on the network.
Video Viewer windows can be viewed using the Best Color Available (slower updates), Best
Compression (fastest updates), a combination of Best Color and Best Compression or in
Grayscale.
You can specify the color depths of individual ports and channels by selecting the
View Color
command in a remote session window. These settings are saved individually per channel.
Contrast and brightness
If the image in the Video Viewer window is too dark or too light, select
Tools - Automatic
Video Adjust
or click the
Automatic Video Adjust
button. This command is also available in the
Video Adjustments dialog box. In most cases, this corrects video issues.
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.
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.
