Optimising The Video Image - G&D FIBREVision-MC4-ARU Installation Und Betrieb

Optimising the video image

The video signal is usually transmitted between the computer module and the user
module in a compressed way. Thanks to this compression, the image on the console
monitors are normally displayed without losses and judders.
The video data to be transmitted and the preset video settings can cause the follo-
wing effects.
Tearing: The monitor image consists of two subsequent frames that are partly dis-
played. The lower part of the image shows a part of the old frame, the upper part
shows a part of the new frame. At the point where both frames touch, the image
appears to be "torn".
NOTE:
The HDIP mode (High Dynamic Image Processing) prevents the tearing effect
and provides the best image quality even for moving images.
Studdering: The number of transmittable pixels is limited by the transmission band-
width. If you have selected a high resolution and the image contents change fast,
some image may be skipped. The video image may seem jerky.
By reducing the colour depth to 18 bits, you can maximise the number of pixels to
be transmitted. Depending on the image contents, this may cause slight colour gra-
diations.
Latencies: The additional processing of the video signal cuase a short latency in the
HDIP mode. This latency may be noticed during fast mouse movements. Deacti-
vate the HDIP mode to avoid such latencies.
Use the setup menu to optimise the video image for each video channel. Optionally,
you can use the setup keys to switch between the following profiles that apply to all
video channels:
