3-9-2. Analog RGB Adjustment
(PVM-14N6A, PVM-14N6E, PVM-
14N6U, PVM-20N6E, PVM-20N6U)
1. Select RGB signal.
2. Input the all gray signal (Fig. 3) into the RGB input.
3. Adjust the luminance to 3 ± 0.2 nit using
58 [C/O|OFFSET|RGB].
4. Adjust the white balance to the color temperature
shown in Table 1 using 59 [C/O|R|FINE|RGB] and
61 [C/O|B|FINE|RGB].
5. Repeat steps 3 and 4 so that the luminance and white
balance become the specifications shown in Table 1.
6. Input the window signal (Fig. 4) into the RGB input.
7. Adjust the luminance to 150 ± 1 nit using 62
[DRV|ALL|RGB].
8. Adjust the white balance to the color temperature
shown in Table 1 using 63 [DRV|R|RGB] and 65
[DRV|B|RGB].
9. Repeat steps 7 and 8 so that the luminance and white
balance become the specifications shown in Table 1.
10. The cutoff varies by changing the drives. Therefore,
repeat steps 3 to 9 until the luminance and color
temperature of the arive and cutoff meet the
specification.
11. Repeat steps 2 to 10 so that the luminance and white
balance of the cut-off side (Fig. 3) and drive side (Fig.
4) become the specifications shown in Table 1.
12. Save the adjustment data.
