Avocent DSViewTM Image clarity, Detection thresholds

52 DSView Installer/User Guide

To move the screen to the right, click the Up Arrow on the Left/Right setting.

Clicking the Down Arrow moves the image to the left. Similarly, the image may

be moved up and down. Moving the mouse into the remote session window

will show if the correction is complete. The point (hot spot) of both DSView

and the target device should be superimposed.

Image clarity

If the image in the remote session window is not clear, select Tools - Video

- Auto Adjust first. This command is also available in the Video Adjustments

dialog box. In most cases, this will correct video problems. In those cases

where clicking on Auto Adjust several times does not clear up a mottled

screen, adjusting the contrast and brightness may help.

First increase the brightness. Do not go more that 10 increments before

moving the contrast. Generally the contrast should not be moved much.

When the packet count gets close to zero, refresh the screen. If the packet

count stays at zero, the video adjustment is completed.

Detection thresholds

In some cases, noise in the video transmission keeps the packets/sec count

up. This may be seen when little dots change in the area of the cursor when

it is moved. Varying the threshold values may result in “quieter” screens and

improved cursor tracking.

Noise Threshold and Priority Threshold values may be modified if you are

using standard video compression. Block Noise Threshold and Pixel Noise

Threshold values may be modified if you are using the DSR DVC upgrade.

Default threshold values can be restored by clicking Auto Adjust Video.

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.
