3 COLOR ADJUSTMENT
• These diagram explains how the color curves were changed for the
best adjustment in steps 4 and 5.
What is the relation between the color and the brightness adjustment?
Brightness uniformly adjusts the amount of light output for the entire
screen and its background. If it is increases too high the background
will become white, too low and many dark colors will not be
displayed. It affects all color controls.
Contrast varies the difference in light output from the lowest to the
highest screen intensities. It is the brightness adjustment for the video
signal area.
After making the color settings, readjust the contrast to get the best
definition and intensity of the colors for the displayed image.
This setup gives the best
color balance.
Adjust the black level
so that the low end of
the curve for each
color (R,G,B) is equal
as see picture 2.
Adjust the white level so
that the high end of the
curve for each color
(R,G,B) is equal as see
picture 3.
