Brightness: On your external test pattern source, select a PLUGE pattern. (PLUGE is an 
acronym for “Picture Line-Up Generation Equipment.”) Figure 4-2 shows a typical PLUGE 
pattern.
Figure 4-2. Typical PLUGE Pattern for Adjusting Brightness
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.
Select Brightness from the Picture Adjust menu and press ENTER. Adjust the level so that:
The darkest black bars disappear into the background. 
The dark gray areas are barely visible.
The lighter gray areas are clearly visible.
The white areas are a comfortable level of true white.
The image contains only black, gray and white (no color).
Contrast: On your external test pattern source, select a stepped, gray-bar pattern like the 
one shown in Figure 4-3
Figure 4-3. Typical Gray Bar Pattern for Adjusting Contrast
