Color Offset is a fine tuning adjustment that requires the use of a test pattern. There
is a copy of the test pattern available on the Help! 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 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 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 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.
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
