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 SVxx54DX4I 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 SVxx54DX4I. Unlike other
filtering algorithms, the SVxx54DX4I 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
