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.

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.

Detection thresholds

In some cases, noise in the video transmission keeps the packets/sec count up, which is indicated by little 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.

•The Block Noise Threshold sets the minimum color change that occurs in a single video block. Increasing the value reduces the network bandwidth. Decreasing the value makes the size of these artifacts smaller.

•The Pixel Noise Threshold sets the minimum color change in a single pixel. Decreasing the value reduces the number of low-contrast artifacts, but increases network bandwidth.

See Adjusting the view on page 30 for information about changing the color depth.

Automatic video adjustment

In most cases, you do not need to alter the Video Settings from the default. The system automatically adjusts and uses the optimal video parameters. The SwitchView IP 1020 remote access device on-board web interface 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.
