Color Offset
Color Offset is a fine tuning adjustment that requires the use of a test pat-
tern. 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 opti-
mum 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 mov-
ing 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.
