Section 3: Operation

Two sets of values are automatically saved with these controls—one value for Input #1, and one for Input #2 (analog). The current set of values depends on which source is in use. This enables a source to be processed correctly via 2 different inputs.

Figure 3.22. Using “Odd Pixel Adjustment”

NOTES: 1) Adjust offset before gain, since offset affects gain. 2) A value of 128 represents no change in normal odd pixel offset or gain. 3) Odd Pixel Adjustment eliminates “1 pixel on, 1 pixel off” artifact only, not any type of larger artifacts.

Color Wheel Calibration — SUBMENU

The Color Wheel Calibration submenu allows you to set the timing of the color wheel in the projector. It is important the color wheel is correctly calibrated for the colors and shades in the displayed image to appear the same. Incorrectly calibrated, the colors will appear in various unmatched shades throughout the image. This adjustment is typically only required when the color wheel is replaced.

To calibrate a color wheel, do the following:

1.Select the Color Wheel Calibration submenu. NOTE: The display automatically changes to the red/blue ramp pattern, which shows the difference in shades of color between two corners most prominently.

2.Move the “Color Wheel Delay” slidebar in either direction until opposite corners of the display are matched.

3.Verify this setting by selecting a new color through “Color Enable” – corners should remain well matched.

4.Perform a final calibration check, by displaying white. The display should appear without any hint of red, green or blue.

Peak Detector

The “Peak Detector” is a fast method for defining individual input levels, and can improve the accuracy of input levels set by the Auto Input Level function. Enabling the “Peak 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 16-step grayscale pattern in which the two black and white bands are known to be at opposite edges of the image, you can watch these isolated areas while adjusting individual blacklevels and input drives until both bands are just visible. Images from this source will then display correct blacks and whites without crushing or washing out.
