Automatic video adjustment
In most cases, you do not need to alter the Video Settings from the default settings. The system automatically
adjusts and uses the optimal video parameters. The MergePoint Unity switch OBWI performs best when the
video parameters are set such that no (0) video packets are transmitted for a static screen.
You can easily adjust your video parameters to ideal settings by clicking on the Auto Adjust Video button in the
Manual Video Adjust dialog box.
NOTE: You can also select Tools - Automatic Video Adjust from the Video Viewer window menu or click the Automatic Video Adjust
toolbar icon to automatically adjust the video.
Video Test Pattern
Clicking the Video Test Pattern button in the Manual Video Adjust dialog box toggles a display of a video test
pattern. Click the Video Test Pattern button again to toggle back to a normal video image.
Vendor-specific video settings
Video settings vary significantly among manufacturers. Avocent maintains an online database of optimized
video settings for various video cards, particularly Sun-specific ones. This information can be obtained from
Avocent’s online knowledge base or by calling Avocent technical support.
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.
