Some external KVM switches generate video noise as well. Try to •

send as much data as your network connection and VNC client allow.
Network latency, which is the total time it takes for a packet to get
to the SV1115IPEXT and come back, has the biggest impact on
perceived performance and usability. Network bandwidth has a lesser
effect, particularly when just moving the mouse around. Only a few
bytes need to be sent when the mouse is moving (and nothing else is
changing on the screen), but the round-trip-time limits the hand-eye
coordination of the user if it is too great. Both actual bandwidth and
measured network latency are shown in the Main Menu.
Using the Advanced Video Tuning Feature
The Advanced Video Tuning menu allows you to adjust the qualities of
the video in your VNC sessions, and can be accessed by clicking the
Advanced button on the Video Tuning VNC menu. While many users
will probably allow the SV1115IPEXT to automatically configure the
