Use the Auto Everything button to automatically fine-tune all three adjustments. If the test
pattern for Color Offset calibration is not present on the screen, then the Color Offset adjustment
is skipped.
Changes/frame indicates the number of 16x16 blocks of video that are being sent, on average,
for every frame of video. With a static image being displayed by the server, this number will be
zero (shown as -nil-). Moving the mouse, for example, will cause the number to jump to about 2
or 3. You may use this number to judge the picture quality as you adjust the controls on this
menu.
Picture Positioning 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 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 managed 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. 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.
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 a high-degree of control of the
video settings of your VNC sessions. See Appendix B for more information on this feature.
Sampling Phase does not normally need to be used since our system tunes the sampling phase
whenever the video mode changes. This button does not require a test pattern, but will perform
