CRYSTALVIEW PLUS INSTALLATION AND OPERATIONS MANUAL
Adjusting the video
All video adjustments are performed from the remote unit. Make
sure all connections are in place and the video from the computer(s)
connected to the local unit are powered up and operating properly.
An online test card has been developed for assisting in the video
skew and color delay adjustments. If possible, display this test card
on the remote unit to adjust. The online location of the test card is:
http://www.rose.com/techsupport/crvtestcard.htm
If displaying the test card is not possible, display some text in a
large font on a white background. Also open a windows application
and check the text in the tool bars and icons on the desktop for
clarity and correct colors.
The RED, GREEN, and BLUE delay for a selected channel can be
adjusted to obtain the clearest image. If possible, use the on-line
test card to perform the skew adjustments. (See Figure 11)
First enter the Command mode ([L-Ctrl] + [L-Shift] + [F10]) then
select a channel to adjust [1, 2, 3, 4, or 0) and then display the test
card. The color skew adjustment lines on the test card are equally
divided into RED, GREEN, and BLUE. If the colors on the line are
not aligned, adjust the skew by increasing the color delay for the
faster color(s). Refer to the example in Figure 10.
