containing 91% (0.64Vp-p) R signal
and 0% level.
(Process/Gamma interaction)
(SVGA or XGA)
Input 2 RGB input.
1. Using CA100, observe the chromaticity of
the 0% window pattern portion.
2. In the screen with missing bits, change R-
Bright until x value for bright red changes to
the black side point where it will not change
any more. From here, raise the level by a
single point where the first missing bits occur
(value change of more than 5/1000), and
adjust the level to this point.
3. Using CA100, observe the chromaticity of
the 91% R signal portion.
4. In the screen with missing bits, change R-
Contrast until x value for bright red changes
to the black side point where it will not

1. Using CA100, observe the chromaticity of
the 0% window pattern portion.
2. In the screen with missing bits, change G-
Bright until y value for bright red changes to
the black side point where it will not change
any more. From here, raise the level by a
single point where the first missing bits occur
(value change of more than 5/1000), and
adjust the level to this point.
3. Using CA100, observe the chromaticity of
the 91% G signal portion.
4. In the screen with missing bits, change G-
Contrast until y value for bright red changes
to the black side point where it will not
change any more. From here, raise the level
