Video Settings

This dialog provides access to all of the key video settings that determine image quality and link performance.

Using automatic configurations

Every setting can be individually subjected to an automatic configuration

 

(click the appropriate ‘Auto’ button) or can also be manually adjusted.

Use the ‘Calibrate All’ button to automatically determine the optimum

Threshold

The threshold is effectively a noise filter that differentiates between valid video signals and background noise or interference. This has the effect of reducing unnecessary video signals between the AdderView CATx and the remote system, thus improving performance.

Phase

The phase setting adjusts the alignment of the host video output and the remote system video display to achieve the sharpest image.

Horizontal Position

Determines the horizontal position of the host screen image within the viewer window.

Vertical Position

Determines the vertical position of the host screen image within the viewer window.

settings for all items.

Note: Before using the ‘Calibrate All’ option, if possible, remove on-screen

display (OSD) elements generated by the AdderView CATx IP or any other

connected KVM switches (such as a host name label or menu). These OSD

elements use different video rates to those of the host system(s) and can

affect the setting of the automatic threshold value. AdderView CATx IP uses

an improved calculation procedure to filter out the effect of these elements.

However, best results are obtained when the screen contains only host

system information.

Note: To maximise performance, the threshold level is automatically

increased by 50% when a slow link is detected.

Note: When the AdderView CATx IP is used with one or more other

switches, the threshold needs to be higher than 32 due to the significant

amounts of ‘noise’ that these switches introduce. The AdderView CATx IP

configuration should detect such noise and adjust the threshold accordingly.

Setting the Threshold manually

Occasionally it can be useful to manually adjust the Threshold setting, in order to achieve a setting that best suits your particular requirements.

1Use the ‘Calibrate All’ function to ensure that all other settings are optimised.

2Click the Threshold left arrow button to decrement the setting by one and observe the ‘Display Activity’ indicator.

3Repeat step 2 until the Display Activity indicator suddenly rises to a much higher level (i.e. 50%). This will mean that you have reached the noise boundary. At this point, increment the Threshold value by 2 or 3 points to achieve an optimum setting.
