to adjust the contrast to a point just below which the white
rectangle starts to increase in size.
Black Level
1. On your external test pattern source, select a PLUGE pattern.
PLUGE patterns vary but generally consist of some combination of black, white and gray areas against
a black background. The example above includes two vertical bars and four shaded boxes. Contrast
and Black Level controls are interactive. A change to one may require a subtle change to the other in
order to achieve the optimum setting.
2. Select Picture Settings > Black Level and press

or

to adjust the black level until:
o
The darkest black bars disappear into the background.
o
The dark gray areas are barely visible.
o
The lighter gray areas are clearly visible.
o
The white areas are a comfortable level of true white.
o
The image contains only black, gray and white (no color).
Color
Color, Hue, and Tint are the ratio of red to green in the color portion of the image. When Color is decreased,
the image appears redder; when it is increased the image appears greener.
1. To adjust the color, use a blue filter when viewing the color bar pattern, as you would for adjusting
color saturation. Like the brightness and contrast controls, the color and tint controls are interactive. A
change to one may require a subtle change to the other in order to achieve the optimum setting.
2. Select Color from the Picture Settings menu and press
▲
or
▼
to adjust it until the cyan and magenta
color bars (on either side of the green bar) appear to be a single shade of blue.
