pattern isn’t scaled or covered up. It’s important to do this operation in
24-bit or 32-bit color video mode (i.e. truecolor). Although the algorithm
may work in 16-bit or 8-bit color video modes, the results will not be opti-
mum and usually it won’t be able to recognize the test pattern.
Pressing the Advanced button will open the Advanced Video Tuning
menu. While the vast majority of users will not need to adjust these set-
tings, it offers added control of the video settings of your VNC sessions.
Sampling Phase does not normally need to be used since the SV-
441DUSBI tunes the sampling phase whenever the video mode changes.
This button does not require a test pattern, but will perform optimally
when used with our standard test pattern. For your reference, the sam-
pling phase number is shown to the right of the Filtering button.
Noise Filter controls the advanced video filtering of our system. Unlike
other filtering algorithms, our noise filter will only remove noise. It does
not degrade the signal quality or readability of small text.You may turn it
on and off using the indicated button, or set it to other values using the
arrows. Higher numbers cause more filtering and may cause artifacts
when moving windows. The most common visual artifact is a vertical line
dropping when moving windows horizontally.You may use the Redraw
button to correct these, or use a lower filter number. At minimum, these
values must be greater than two.
Accessing KVM Features
Once you can access and configure the networking component of the
Server Remote Control, you can use it to select and control the managed
computers connected to it. This section describes how to use the on-
screen display (OSD) system to manage your computers. Once you have
established a VNC session with the SV441DUSBI, you can access the
KVM features as though you were at a local console.
