Color Offset
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 perform 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.
Advanced
Pressing this 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 SVxx53DXI 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 the SVxx53DXI. Unlike other filtering
algorithms, the SVxx53DXI 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.
