4. Select the “Gray-10” in the “TEST PATTERN SELECT” menu.
5. Measure the luminance of screen and adjust the lamp power in the “LAMP POWER” menu so that
the luminance is 16 ft-L.
After adjustment, the luminance is lowered by approximately 2 ft-L.
6. Select “DCDM” in the “COLOR SPACE” menu.
n
When “COLOR SPACE” is not available, input a video signal.
7. Check the W values of “Target Color Gamut” is x = 0.314, y = 0.351.
8. When the W values are mismatch, click the
[TARGET|RECALL]
button.
9. Click the
[RESET]
button fi rst, and then click the
[APPLY]
button.
10. Select “Red-1”, “Green-1”, “Blue-1” and “Gray-8” respectively in the “TEST PATTERN SELECT”
menu. Then, measure x and y values respectively.
11. Enter the x and y values in Input Color Measurement in the “COLOR SPACE” menu.
12. Click the
[CALC]
button fi rst, and then click the
[APPLY]
button in the “COLOR SPACE” window.
13. Select “Red-1”, “Green-1”, “Blue-1” and “Gray-8” respectively in the “TEST PATTERN SELECT”
menu. Then, measure the x and y values respectively and compare the results with the following
speci
fi cations within an error range of 0.006.
x y
Red-1 0.680 0.320
Green-1 0.265 0.690
Blue-1 0.150 0.060
Gray-8 0.314 0.319

15. Click the “FUNCTION MEMORY” tab.
The FUNCTION MEMORY window is displayed.
16. Adjust the lamp power in the “LAMP POWER” menu so that the luminance is 14 ft-L.

In this procedure, the luminance is not correctly 14 ft-L. When the correct luminance is required, input
“Gray 10” of the SONY color patch by LMT-300, and adjust the lamp power.
CSC adjustment for virtual white
The D61 WP (White Point) of DCDM standard speci fi ed by DCI SPEC is considerably green-tinged.
Some people in the fi lm industry recommend D65 or D55 WP. However, when the software created by
D65 or D55 WP is installed in the display adjusted by DCI SPEC, some colors run out of color space
causing a clipping problem. To solve this problem, Virtual White is proposed. Its chromaticity range is the
same as DCDM; WP x=0.319, y=0.3338. Also, the data for realizing 14 ft-L is slightly changing. By this,
the clipping problem does not occur in any of D65, D61 and D55. If Virtual White is used for adjustment,
there is no problem in the DCI SPEC signal.

For this unit, “Virtual White” can be selected in COLOR SPACE.
