to perform this operation in 24-bit or 32-bit color video mode (i.e. True
Color). Although the algorithm may work in 16-bit or 8-bit color video
modes, the results will not be optimum 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
settings, it offers added control of the video settings of your VNC
sessions.
Sampling Phase does not normally need to be used since
SV1115IPEXT 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 sampling 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.
Getting Peak Performance
Choose the best video mode
We recommend using 60Hz refresh rate and 1024x768 resolution. •
Using a smaller resolution like this allows you to fit multiple windows
on your remote desktop. Higher refresh rates stress the video card’s
quality and do not provide any additional information or benefit.
Noisy video cards
A digital KVM works by converting the analog video signals emitted •
by your video card into digital data. If there is noise on that signal,
then it must also be digitized and sent over the network. Quality
video cards, in our experience, offer better performance simply
because they don’t add analog noise.
