menu of the integrated web server. You must arrange for that image to
be shown on the host computer. Do not allow scaling, cropping or any
other changes to that image. Press the Auto button and the system
will calibrate color for the best possible picture in approximately one
minute. If the system cannot find the test pattern on the screen, it will
say so. Check that the pattern isn’t scaled or covered up. It’s important
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 the IP KVM
switch 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.

• 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.
