The option Noise Filter defines how IP-KVM reacts to small changes in
the video input signal. Turning on the noise filter can help reduce video
flickering that is often caused by distortions, as well as lowering
unnecessary bandwidth consumption. A large filter setting needs less
network traffic and leads to a faster video display, but small changes in
some display regions may not be recognized immediately. A small filter
displays all changes instantly but may lead to a constant amount of
network traffic even if display content is not really changing (depending
on the quality of the video input signal). All in all the default setting
should be suitable for most situations.

Clock
Defines the horizontal frequency for a video line and depends on the
video mode. Different video card types may require different values
here. The default settings in conjunction with the auto adjustment
procedure should be adequate for all common configurations. If the
picture quality is still bad after auto adjustment you may try to change
this setting together with the sampling phase to achieve a better
quality.
