Picture Positioning
This option affects the image position on your screen. If you see a black line on
either side of your screen, or at the top or bottom, you can use the arrow buttons
to shift the image in that direction. Pressing
Auto
does the same thing for you
automatically. Use
Save to
save the changes you have made manually. Since this
adjustment depends on the video mode, separate values are stored for each video
mode.
Color Offset & Gain
This 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.
Download that image to the host computer(s). 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 (that is, 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.
Advanced
Press this button to open the Advanced Video Tuning menu. While the vast
majority of users will not need to adjust these settings, it offers a high degree of
control of the video settings of your VNC sessions.
Sampling Phase
This option does not normally need to be used since the ServSwitch tunes the
sampling phase whenever the video mode changes. This button does not require a
test pattern, but will perform optimally when used with the ServSwitch unit’s
standard test pattern. For your reference, the sampling phase number is shown to
the right of the Filtering button.
