Bandwidth Usage for KX II HD 1080p Resolution?

A customer recently asked how much bandwidth the Dominion KX II KVM-over-IP access uses, specifically for the full HD (1920x1080) resolution.  This is a common user question.  The answer is as follows.

There is no fixed bandwidth for the KX II products. The bandwidth depends on how much change there is on the video screen at a particular instant. So if there is no change on the screen, then there will be no or very small amount of bandwidth. If the user is playing a movie, then there could be a very large bandwidth. Of course with larger video resolutions, then there will be more bandwidth than with a smaller resolution.

There is a feature in the KVM clients to see the amount of bandwidth being used. This can be used to check the bandwidth.  There are several settings to decrease bandwidth, as well as some helpful tips on managing bandwidth in the KX II User’s Guide called ‘Bandwidth and KVM-over-IP Performance’ that the customer may find useful.
