Video Settings through the HTML
To enable local video port, select this option. This option decides if the local
video output of SP1200A is active and passing through the incoming signal
from the host system. The option Noise Filter defines how SP1200A 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.
