Network Performance
The IP KVM switch will always send as much data as it can, given what’s happening
on the screen and the actual network performance. When nothing is changing on the
video screen, zero bytes are sent over the network. If the whole screen is changing,
then the unit will 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 IP KVM switch
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 IP KVM switch to
automatically configure the video properties, you can use this menu to exercise a great
deal of control over the settings if you wish.
The Presets section contains up to sixteen different settings, plus the factory setting.
If a number is highlighted, then that preset has been programmed with valid settings
and may be used. Note that the Factory
preset is always available. Simply click on the appropriate button and those settings
will be restored. To save settings to a preset, click on the Save->Preset button in the
Actions pane. The preset buttons will highlight. Click the desired preset button to save
the values. Note that any previous settings assigned to that button will be lost. If you
do not wish to save the presets after clicking the Save->Preset button, click the Save-
>Preset button a second time and the save function will be cancelled.
