(If you want to connect more than this number of monitors, we recommended that you use

a distributor.)

When the tile mode is configured via DVI cables, only the monitor that receives first signals can

play HDCP-encrypted content. (The DVI Out port does not support HDCP).

If the signal cable between the product and your PC is too long, make sure to use the DVI (RGB)

booster or DVI (RGB) optical cable.

If input signals are received through the HDMI/DP cable, multiple monitors cannot be connected

via the DVI Out port"

C-1. Two ways of manual adjustment

1) Manual Adjustment with SuperSign C

> You can adjust white balance manually by changing R/G/B gain

> Except some special cases such as broadcasted video wall, You should not change R/G/B offset value. It may cause side effects to the whole color level.

Note) In case of white balance adjustment at broadcast station, it can be needed to control R/G/B offset

because it should be adjusted based on color temperature of broadcast camera. )

Warning (Very Important!)

If the set the gain value to 192 or higher, some color may not be rendered properly. Because the max gain value is 192

Recommend changing gain value under 3 steps per each color, if you want to change

D. Appendix 2 : Troubleshooting

Problem

Did Calibration fail?

Resolution

Refer to the Version Matching chart.

And If needed update both SOC(Flash) and Micom to the latest version.

Is there any abnormal working at

SSC or monitor?

(e.g : R/G/B gains are over 192 after calibration or SSC is hang-up or terminated abnormally and so on.)

Is the white color different between video wall screens after calibration?

There is color mismatching after calibration.

Did you use Duplication function?

If the result is same, please adjust manually.

Note) If you set color temperature as over 11000, working.

More than 2 screens may have individual color and brightness uniformity, this lack of uniformity could make them to look different.

So proceed the manual adjustment white balance more correctly.

There could be problem when you use Duplication function because of the uniformity of panel.

If you used Duplication function to reduce processing time,
