2.1 Preparation
2Color Balance Adjustment
Enter the factory menu through MENU+1234 on the remote control to check the version information and the
production date of the software.
Note: Try not to use different software which may lead to problems due to customized effects.
Make a pure white and a pure
black picture (red, green and blue
are both 255, the following picture
is the setting method of the
drawing tool in the WIN10 system,
other systems are similar), If it is a
scene with a lot of static files, you
can create pictures similar to pure
red, pure green and pure blue, or
use a small tool to generate it
yourself, in following test will be
used.
It is recommended to use the host computer for debugging work, which is convenient and
quick to operate.

Use the host computer control:
after Unicom host computer, first
perform the overall reset action,
the password is “cjfw”, Ensure
that the software is in the default
factory state.
NOTE: To avoid the reset action during the customer is in use, do not send this password to the
customer.
After the screen is reset, set the ID address of each screen through the host computer or
remote control.
NOTE: Press the ID key on the remote control to call up the setting interface, and the host
computer needs to enter the super user interface; Part of the parameters and parameter
positions needed to adjust the screen:

Some parameters and parameter positions needed to adjust the screen.
PC software:
Open the image adjustment interface, and the adjustment is mainly based on "brightness",
"red gain", "green gain", "blue gain" and "saturation". When adjusting the screen, you need
to select the corresponding screen in the main frame. Then adjust the parameters in
"Image Adjustment".
Please do not do any operation on the backlight brightness.

Use the remote control to press
the MENU key button to access
the “Color” menu.
The parameters are mainly red
gain, green gain and blue gain in
white balance.
2.2 Adjustment
Figure 2.1
Play the
black picture in full
screen, as shown in figure 2.1,
and observe whether the picture
has whitening or uneven the
brightness.
•Screen whitening: Reduce the
brightness value of a single
screen.
•The black field of the screen
is uneven
: This situation is
caused by the unevenness of
the light guide plate. This state
is not avoided. It is necessary to
increase the brightness value to
make the screen white as much
as possible, Adjust the value
within 10 unit values.

Figure 2.2
After the black picture is adjusted,
the created pure white picture will
be played in full screen at this
time.
Stand in front of the screen to
observe the splicing and select
one of the most gray and dark
screens, as shown in the figure
2.2.
Taking the darker screen as the benchmark, adjust the brightness and grayscale of other
screens to a similar level to the dark screen.
Specific method: Reduce the brightness of the lower screen of the white screen by reducing
the red, green and blue gains in the color temperature of a single screen. For example, the
above picture should be based on the first screen in the upper left corner, and the surrounding
screens should reduce the red, green and blue gains one by one to achieve dark degree of
consistency.
Note: Try not to operate by reducing the brightness. First, the brightness has changed after
adjusting the black point, and second, the brightness change will also cause a large difference in
color temperature.
The solution to the color deviation between the screens under the white screen:
•Picture is reddish: reduce the "red gain" or increase ("green gain" and "blue gain")
•Picture is greenish: Decrease "Green Gain" or increase ("Red Gain" and "Blue Gain")
•Picture is bluish: Decrease "Blue Gain" or increase ("Red Gain" and "Green Gain")
•Picture is yellowish: increase "Blue Gain" or decrease ("Red Gain" and "Green Gain")
•Picture is purple: increase the "green gain" or decrease ("red gain" and "blue gain")
•Picture is too blue: increase the "red gain" or decrease ("blue gain" and "green gain")
Note: Changing the "Blue Gain" has a great impact on the brightness of the picture, try to minimize
the changes to the "Blue Gain"

Figure 2.3

In response to the problem of
inconsistent colors in the solid color
screen raised by the customer, first
confirm that the white screen has
been debugged, and then refer to
the following method, the effect is
shown in the figure 2.3
•The difference in color shades is slight: it can be improved by increasing the "saturation" of
the screen with slightly lighter colors.
•Large difference in color shades: it can be improved by reducing the "saturation" of the screen
with higher color density.
•The problem of color cast, for example, some screens are watery red or purple under the red
screen, and some screens are green or blue under the yellow screen. At this time, please
make sure that the colors of pure red, pure green and pure blue are not too different; if the
color cast problem cannot be reduced by adjustment, please try to reduce the "saturation" to
improve such problems.
Note: Reducing the saturation will result in a lighter color, so the one with the closest visual effect
is the best.
