BRIGHTNESS: On your external test pattern source, select a PLUGE pattern. (PLUGE is
an acronym for “Picture Line-Up Generation Equipment.”) Figure 4-3 shows a typical
PLUGE pattern.
Figure 4-3. 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 menu. Using the left- and right-arrow (
)
buttons, adjust the brightness 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).
Brightness and Picture level controls are interactive. A change to
one may require a subtle change to the other in order to achieve
the optimum setting.
