Operation

72 D-73d Series Installation/Operation Manual

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 menu and press ENTER. 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).

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

Select Contrast and press ENTER. Adjust the contrast to a point just below which the

white rectangle starts to increase in size.

Brightness and contrast controls are interactive. A change to one

may require a subtle change to the other in order to achieve the

optimum setting.
