Target video settings
The Image Capture Width, Pixel Sampling/Fine Adjust, Image Capture Horizontal Position and
Image Capture Vertical Position adjustments affect how the target video is captured and
digitized. They are seldom changed.
The image capture parameters are automatically changed by the Automatic Adjustment
function. A special image is required on the target in order to make accurate adjustments
independently.
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.
