Installation

1. There must be at least two consecutive white pixels present in the

Note image for the “Pre-Calibration” function to work properly. Otherwise, input levels may produce skewed colors, particularly in non-video images.

2.Uncheck this item before exiting this menu.

•Black Levels and White Levels: To check your image and adjust these controls:

1.Make sure overall “White Level” (contrast) and “Black Level” (brightness) settings are both set to near 50. (Not required for “Pre-Calibration” adjustment.)

2.Check the color temperature setup using an internal grayscale test pattern, making sure to obtain a neutral grayscale. (Not required for “Pre-Calibration” adjustment.)

3.If the blacks and/or whites appear OK, input levels do not need adjustment. If black levels are too high (and/or whites are too low, which is rare), you likely have a noisy source that is producing skewed input levels. Continue with Step 4.

4.Temporarily enable “Pre-Calibration” in the White Balance submenu. Wait for all six values to stabilize. Alternatively, do not use “Pre-Calibration” — reduce black levels manually instead. Judge by eye and change one or more of the six levels as necessary to obtain proper blacks and whites. You may want to see only a certain color while adjusting; if so, use the “Color Enable” option (described below).

5.Clear the “Pre-Calibration” check box and exit the White Balance menu.

•Auto Color Enable: When a check mark is present, selecting a specific black level or drive to adjust will automatically enable the corresponding color in the display. Delete the check mark to see all colors.

•Clamping: This option can brighten the image produced from certain high-resolution, high-frequency graphic sources. For almost all sources, the best clamp location is automatically selected by the projector.

• Use the normal Back Porch location if the image is either sufficiently bright or overly bright.

• Select Sync Tip if the image appears unusually dim, if there are horizontal streaks across the image, or if there is significant color drift. This moves the clamping pulse from the normal back porch location (which is likely too short) to the tip of the horizontal sync pulse.

• Tri Level is typically recommended for an HDTV source where the back porch is also short, or for video sources or any RGB source with sync information included on the video (for example, sync-on-green).

•Clipping Detector: The Clipping Detector is a tool to assist with defining individual input levels, enabling you to accurately set the white balance for any particular source with the appropriate image.

Enabling the Clipping Detector activates a special operating mode for detecting only pixels that are considered black or white; all other levels are displayed as a mid-level gray. When used with a smooth grayscale pattern in which black and white are known to be at opposite edges of the image, you can watch these isolated areas while adjusting individual black and white levels until both black and white edges are just visible and distinguished from neighboring pixels. Images from this source will then display correct
