Other factors include the server’s video resolution, networking speed and
characteristics, client PC resources, and video card noise.
The Dominion KX II has very sophisticated video processing algorithms
that optimize bandwidth and performance for a variety of environments.
In addition, they are highly configurable since there are many settings to
optimize bandwidth usage. In particular, the Connection Speed setting in
the remote clients (VKC, MPC) can be set to reduce the bandwidth used.
Unlike KX I, the Noise Filter parameter does not generally have a large
role in reducing bandwidth or improving performance.
How much bandwidth does the Dominion KX II use for common
tasks?
Bandwidth primarily depends on the user's task and actions. The more
the server's video screen changes, the more bandwidth is utilized.
