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 3.23. 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 two color
wheels in the projector. It is important the
color wheels are 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. Typically, this
adjustment is only required when a color wheel is replaced.
1. Select the single lamp operation mode that corresponds to the color wheel you
want to calibrate. For example, select “Single Lamp 1” when calibrating color
wheel 1 and “Single Lamp 2” when calibrating color wheel 2.
2. Enter the Color Wheel Calibration submenu – the Color Ramp test pattern will
automatically display and the “Color Enable” option will automatically switch to
White
.
3. Adjust “Color Wheel 1 (or 2) Delay” so the transitions across each color bar
appears smooth.
4. Repeat Step 1 – Step 3 for the other color wheel. NOTE: Wait for 35 seconds
when requesting a change in single lamp operation modes to allow for one lamp
to warm up and the other to turn off.
5. Verify adjustments by choosing different colors in “Color Enable”.
NOTE: Upon entering the Color Wheel Calibration submenu, the “Color Enable”
option automatically switches to white and the color ramp test pattern displays.
