Splice mode
The system provides two splicing methods for users to choose. As
mentioned above, you need to select the “splicing method” according to the
LED screen width and height ratio and the use scenario. "
It is more suitable; when the shape of the LED screen is a long screen,
it is more appropriate to choose "horizontal stitching". When selecting the
splicing method, you should also pay attention to whether the "LED screen
can set the maximum number of points" displayed in the prompt
information bar meets the actual LED screen width and height
requirements.
After clicking the 【OK】button, it will be confirmed. At this time, the
system will automatically jump to the “LED screen parameter” setting
menu.
Horizontal splice
In the non-menu state, click the [OK] button to enter the main menu,

www.onbonbx.com 第 13 页
then select "splicing mode", and then select "horizontal splicing" to pop up
the following menu:
After clicking the "OK" button, it will be confirmed. At this time, the
system will automatically jump to the "LED screen parameter" setting menu,
and the user needs to continue to complete the relevant parameter settings.
In the horizontal splicing mode, the four DVI output ports OUT1~OUT2 of
the splicer are arranged in a horizontal direction. At this time, the LED
screen can be set to a maximum number of points: 8000 in the horizontal
direction and 2000 in the vertical direction, and the total number of points
cannot exceed 5.1 million points. For details, see The setting instructions of
"LED screen parameter" will follow. This splicing method is more suitable
for the screen with long shape.
Vertical splice
In the non-menu state, click the [OK] button to enter the main menu, and
then select "stitching method", then select "vertical stitching" will pop up the
following menu:
After clicking the "OK" button, it will be confirmed. At this time, the system
will automatically jump to the "LED screen parameter" setting menu, and
the user needs to continue to complete the relevant parameter settings. In
the vertical splicing mode, the four DVI output ports OUT1~OUT2 of the
splicer are arranged in a vertical direction. At this time, the LED screen can
be set to a maximum number of points: 4000 (horizontal), 3840 (vertical),

www.onbonbx.com 第 14 页
and the total number of points cannot exceed 5 million For details, please
refer to the setting instructions of "LED screen parameter" below. The
splicing method is more suitable for the ultra-high-definition LED large
screen in the shape of a vertical bar.
LED screen parameters
LED size
Click【OK】as to enter into main menu, then choose “LED setting”, as
below:

www.onbonbx.com 第 15 页
After the LED screen parameters are set, move the cursor to [OK] and
press the [OK] key to save the data. If the "splicing method" is changed
before the LED screen parameters are set or the LED screen width
parameter crosses the boundary under horizontal splicing The system will
be in the reset state, users need to wait patiently for the system to reset.
Pay attention to the value range of the LED screen size and the total load
points of the LED screen:
Horizontal splice
（1）When the total width of the LED screen <= 4096
LED screen total height <= 2000;
Value range of OUT1~OUT2 output port:Width 0~4000, height 0~2000
Note: When the width and height of an output port in OUT1~OUT4 is 0,
it means that the output port has no output.
（2）When 4096 <total width of LED screen <= 8000
The total height of the LED screen: It is determined by the
maximum number of points that the LED screen can carry (5.1 million
points).
The system will automatically limit when setting.
Value range of OUT1~OUT2 output port:Width: 0~4000, height: the same
as the total height of the set LED screen
Note: When the width and height of an output port in OUT1~OUT2 is 0, it
means that the output port has no output.
Vertical splice

www.onbonbx.com 第 16 页
LED screen total width <= 4000
LED screen total height <= 3840
And the total number of points on the LED screen can not exceed 5 million
points.Value range of OUT1~OUT4 output port:Width 0~4000, height
0~2000
Note: When the width and height of an output port in OUT1~OUT2 is 0, it
means that the output port has no output.
Layout
Pls go to the layout image by press OK when at the status of non-menu.
Horizontal width: the adjustment range is 120 ~ the maximum number of
points can be set in the horizontal direction.
Vertical height: the adjustment range is 68 ~ the maximum number of
points can be set in the vertical direction.
Horizontal start: The minimum value is 0, and the maximum value is the
maximum number of horizontal points minus the horizontal width.
Vertical start: The minimum value is 0, and the maximum value is the
maximum number of vertical points minus the vertical height
note:
(1) Up to 4 screen display windows can be opened in each splicing mode,
and the screen 1 window is always open
(2) When two or more screens are open, if the screens overlap, it may
cause display confusion;
(3) Click the "MODE" shortcut key on the front panel to enter the system
"fixed mode call" menu, you can quickly open the desired screen display
window.
(4) The picture display window can float arbitrarily between each DVI
output window OUT1~OUT2 without its boundary.
(5) The screen display window opened outside the size mapping range of
the LED screen can be used as the input source monitoring window.
1. LAN OUTPUT SETING
In the non-menu state, click the [OK] button to enter the main menu,

www.onbonbx.com 第 17 页
then select "Output Settings", and then select "Network Port Output
Settings" to enter the network port output settings menu:
note:
(1) As mentioned above, when the "accept card connection" setting of
each LED screen's network port is completed through the PC control
software, the LED screen size and so on will be automatically calculated
and updated to the controller synchronously, so generally no need to set
the LED screen parameters Including the size of the LED screen and the
parameters of each network port)
(2) When you need to "arbitrarily splice" or set for each network port,
please pay attention to the value range and the number of loaded points of
a single network port width and height
:Horizontal width: 256~4000
Vertical height: 128~3840
Horizontal width x vertical height <= 655360 (when width> height)
Horizontal width x vertical height <= 652738 (when width <height)
Image size
Click ok then go to output setup ,then select the image size adjust:

www.onbonbx.com 第 18 页
Note：
Regardless of whether the input image ratio is 4:3 or 16:9, the output
image is displayed by "full screen" by default, so in some cases it will cause
equal proportion distortion of people, at this time, you can change the width
and height of the image through "display window adjustment" ratio.
2. Pixel to pixel
In the non-menu state, click the [OK] button to enter the main menu, then
select "Output Settings", and then select "Point-to-point output" to enter the
point-to-point output menu.The default state of point-to-point output is off.
When the point-to-point output is in the "on" state, the input signal is
directly output to the output without any processing by the processor, that
is, the output image and the input image are completely point-to-point.
note:
(1) When the point-to-point output is in the "on" state, the controller
outputs the input image to the large LED screen without any scaling at this
time.Therefore, it is very convenient to debug the LED screen module (plot
point display, etc.);
(2) The point-to-point output is only valid in the range of 3840*2160;
(3) When the input resolution is set to the same size as the LED through
the "Advanced Options-Input Resolution" menu, the image can be
displayed without any scaling, so the best display effect can be achieved.
(4) When the point-to-point output is turned on, the image capture will be
automatically turned off.

Option
Click【OK】as to enter into main menu--”OPTION”, as below:
1. Input EDID
It offers EDID editing function of DVI/HDMI input signal source, means, the
recommended resolution of input signal source. In WIN7 system, when the
“input EDID (recommended)” is modified which is read by PC, the output
resolution of PC will be modified too;But for WIN10 system, output
resolution of PC won’t be changed, users need to operate manually.
By setting the input resolution, the user can realize the input and output of
