Runco CL-410 and CL-420 Owner’s Operating Manual 35

Connect your test pattern source to the input that you are calibrating and proceed as

follows. Perform the adjustments in the order listed here.

Brightness: On your external test pattern source, select a PLUGE pattern. (PLUGE is an

acronym for “Picture Line-Up Generation Equipment.”)

Figure 4-5 shows a typical PLUGE

pattern.

Figure 4-5. 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. 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).
