Avocent DSViewTM Adjusting Video Parameters

50 DSView Installer/User Guide

Adjusting Video Parameters

In some situations, DS users may wish to view several target devices at the

same time on the same screen.

In most cases, you will not need to alter the Video Settings from the default.

The system will automatically adjust and use the optimal video parameters.

DSView performs best when the video parameters are set such that no (zero)

video packets are transmitted for a static screen.

To automatically adjust video parameters:

You may easily adjust your video parameters by clicking on the Auto Adjust

Video button, which instructs the DS/DSR appliance to optimize the video to

ideal settings.

Customizing video parameters

DS users who wish to fine tune their video performance may do so by select-

ing Tools - Video - Manual Adjustments in the remote session window. This

displays the Video Adjustments dialog box. This dialog box will appear in one

of two ways, depending on whether you are using standard video compression

or the DSR DVC upgrade. See figures 4.6 and 4.7.

NOTE: The DSR DVC upgrade is standard on all newer D S / DSR a ppli anc es. O lde r DS / DS R

appliances use standard video compression. For DSR DVC upgrade purchase information, conta ct

Avocent Technical Support or your Avo cent reseller.
