White Balance: For each color temperature, you can fine-tune the white balance parameters to remove any trace of color from the white areas of the image. To do this, select a color temperature as described above and press MENU. Then:

•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.

•Offset: Use the Offset controls in the White Balance sub-menu to correct color imbalances in the dark areas of the image. A good way to do this is to use a test pattern consisting mostly of dark gray areas, such as a 30 IRE “window” pattern. If the gray areas contain traces of red, green or blue, decrease the Offset for that color.

To reset the white balance settings to the factory default values, select Reset. Then, press the right-arrow button to select ON and press OK or MENU.

You must set the Advanced OSD option (in the Function menu) to

Note ON in order to access the Gamma, Dither, Black Level and Color Chart settings. Refer to Advanced OSD on page 40.

Gamma: The Gamma control determines how gray shades are displayed between minimum input (black) and maximum input (white) for all signals. A good gamma setting helps to optimize blacks and whites while ensuring smooth transitions for the “in-between” values utilized in other grays.

Unlike brightness and contrast controls, Gamma allows you to lighten or darken the overall tone of your images without changing the extremes. All images will be more vibrant while still showing good detail in dark areas.

The default Gamma setting of 2.2 is appropriate for most typical home theater environments.

Dither: Dithering can improve detail in some signals, especially in dark areas of an image. Select Dither from the Picture Adjust menu and choose the dither method that is appropriate to the type of source material (STILL, MOTION or DIFFUSE). Or, use the default setting of AUTO.

Black Level: This control compensates for incoming elevated black levels present in certain video signals, and ensures that blacks in the display are neither “crushed” (where dark grays appear black) nor excessively elevated (where blacks appear dark gray).

By default, the CinemaWall automatically determines the best setting according to the type of incoming video signal. For some types of video, you may want to override the setting. Generally, if black appears crushed when brightness = 32, choose “NORMAL.” If black appears excessively elevated, use “STEP 1” or “STEP 2.”
