Color Enable; Odd Pixel Adjustment - Christie RPMX-D132U User Manual

Section 4: Advanced Configuration and Controls

4.9.4 Color Enable

Select which color or colors you want to see. This is useful while working with color temperature, input levels
or other special setup parameters. Colors can also be enabled or disabled by entering the corresponding
function code listed on the back of the standard remote keypad.

4.9.5 Odd Pixel Adjustment

Factory-set and rarely required by user. Source must be >110 MHz.
NOTE:
When using some RGB sources, you may need to adjust the normal gain or offset of odd pixels in relation to
even pixels. This will smooth out very narrow (1-pixel wide) "checks" or vertical stripes that indicate adjacent
"on" and "off" pixels. Although offset and gain slidebars can be adjusted individually and manually, using the
Level Detector simplifies this process, see
1. Use an external analog native-sized continuous grayscale test pattern with at least 256-levels.
2. Turn "Level Detector" on.
3. Set "Level Value" to ~200. The image is now black-and-white (or black-and-one color, if you use "Color
Enable" function).
4. Adjust offset for one color. As you adjust, you will see half of the pixels move, the other half will not.
5. Adjust until the two transition regions overlap. The stripe of noise will be minimized, defined by the value
in the slidebar.
6. Continue to adjust offset for the other two colors.
7. Set "Level Value" to ~800. The image is now black-and-white.
8. Repeat Steps 4 and 5, but adjusting gain for each color. Adjust offset before gain, since offset affects gain.
9. Once all colors are adjusted, your RGB source is OK. Tweak adjustments as required.
NOTES:
1) A value of 128 represents no change in normal odd pixel offset or gain.
2) Odd Pixel Adjustment eliminates "1 pixel on, 1 pixel off" patterns only, not any type of larger patterns.
