3.2.3 Adjusting to Video Sources

Video adjustments are quite a bit like the controls on a television receiver.
Adjusting the picture
1. Select a video source in the Picture menu. When
the VIM option is installed (Video Input Module)
Margay has available
a. one composite video,
b. one S-Video, and
c. one component (YPbPr) input.
2. Press on the remote.
LEVEL
These controls are also used for analog sources when
you chose YPbPr Colorspace.
Now you have two choices.
• Adjust using any picture from the video source.
• Adjust using a standard color bar pattern from the
source.
Adjusting with any picture
This procedure must be done after you adjust color
balance (page 52).
1. Choose pictures that have blacks and whites rep-
resented as well as a variety of colors.
2. Adjust Contrast, Brightness, Saturation and Hue
on one Margay until it looks satisfactory.
3. Adjust all the other Margays in the wall so they
have the same values for Contrast, Brightness,
Saturation and Hue as the first Margay.
Adjusting with color bars
1. If possible, use a color bar pattern from the video
source you will use for the program material. You
cannot use the color bar from the Test Patterns
menu.
2. In the Picture menu, check Blue Only. You should
see only the alternate color bars, all of them blue.
3. Adjust Saturation to make the outer two color
bars match. Match them in brightness; they will
already match in color.
4. Adjust Hue to make the inner two color bars
match.
5. Uncheck Blue Only
When a video source is selected, Auto Setup Options is
not available. Adjustments must be made manually.

6. If the color bar pattern has a pluge, you can use it
to adjust Brightness.
Adjust Brightness so you cannot
see the different between these
two marks,
but you can see the difference
between these two marks.
