Chapter 4—Setup Adjustments

4.8.3. Color Balance (Grey Scale)

Color balancing sets the color balance over the entire screen. This adjustment may be necessary after performing Threshold and Sensitivity procedures. The Grey Scale test pattern should be grey throughout the entire screen area with a normal, gradual brightness transition from bar to bar (no perceived coloration). If the test pattern is not grey throughout, color balancing is necessary.

Threshold and Sensitivity Offsets can be made for the entire screen to get proper color balance for the bright and dark areas.

To check for proper Color Balance (Grey Scale):

1.Access GREY SCALE from the TEST PATTERN MENU.

2.Toggle the RGB KEY and verify all colors are selected and on screen.

3.Observe the two or three darkest bars in each of the four (4) sections

of the test pattern. If any color is too prominent in these two or three bars, adjust the Threshold Offset (see instructions following for adjusting the Threshold Offset) for that color.

4.Observe the two or three brightest bars in each of the four (4) sections of the test pattern (refer to Figure 4.0-17 on page 4-31).

If any color is too prominent in these two (2) or three (3) bars, adjust the Sensitivity Offset (see instructions following for adjusting the Sensitivity Offset) for that color.

NOTE: A color may appear too weak, due to the other two (2) colors being too dominant. If so, slightly increase sensitivity offset for the weak color.

To adjust the Sensitivity Offset for the best Color Balance:

1.Toggle the RGB KEY and select the color that is too prominent in the brightest bars .

2.Access SENSITIVITY OFFSET from the CONVERGENCE MENU.

3.Use the up/down arrow keys to increase or decrease the Sensitivity Offset slightly so that the brightest bars in the test pattern are without color, i.e. grey. Make a note of the offset data number before making any adjustments in case an error is made and the original setting is needed. Recheck the test pattern for a normal, gradual transition from bar to bar. If increasing the Offset, avoid overadjusting any of the colors. Leave a normal, gradual brightness transition between the two (2) brightest bars.

NOTE: The two (2) numbers that appear in the box on the screen represent the lowest and highest Sensitivity settings on the screen. If either of these settings is at the minimum (0) or maximum (255) there will be no adjustment range available to adjust the Offset. This means that one (1) area on the screen has been adjusted too high or too low during the Sensitivity adjustment and is restricting the Offset adjustment.

Before the Offset can be adjusted, this area must be increased or decreased to allow for more range to perform the Offset adjustment.
