Adjustment Procedure:

1. Use an SVGA (MP8670) or XGA (MP8745) VESA

(60) timing signal to input a 0.35V p-p G primary

color signal (50% Green).

2. Measure the illumination at points No. 2 and No. 3.

The Values should be:

No. 2 = Y2 (lux)

No. 3 = Y3 (lux)

3. Determine which point (No. 2 or No. 3 has the

higher illumination.

4. Adjust the higher to match the lower. For example,

if Y2 > Y3, Adjust No. 2 G to ± 10 of the value of

Y 3.

Y2 = y3 ± 10

This completes the Green color adjustment.

5. Use an SVGA (MP8670) or XGA (MP8745) VESA

(60) timing signal to input a 0.35V p-p white signal.

6. With a Chroma meter (CL-100) measure point 1.

Make note of the value, this is your benchmark for

the rest of the adjustments.

• x = x1

• y = y1

√√ Notes

x value is adjusted with “R”

y value is adjusted with “B”

Adjust “B” first then “R” for each Value
