DynamicBlack: Select DynamicBlack from the Advanced menu to enable (On)

or disable (Off) the DynamicBlack actuator in the optical engine. DynamicBlack

uses a dynamic iris that modulates light to the DMD based on the actual

content of the video material. Planar recommends that you disable

DynamicBlack before adjusting Brightness, Contrast or other image settings.

Adaptive Contrast: Adaptive Contrast enhancement expands the light and

dark portions of an output image according to the mean luminance of the

input image.

RGB Adjust: To remove any trace of color from the white areas of the projected

image, choose RGB Adjust from the Advanced menu and press ENTER. This

displays the RGB Adjust sub-menu, shown in Figure 4-9.

• Gain: Use the Gain controls to correct color imbalances in the bright areas of

the image. A good way to do this is to use a test pattern consisting mostly of

solid white areas, such as an 80 IRE “window” pattern. If the white areas

contain traces of red, green or blue, decrease the Gain for that color.
