Note ：
After the PC screen control software is used to complete the settings of the “connect receiving
card” of each network port of the LED screen, the size of the LED screen is automatically calculated
and updated to the controller synchronously, so it is generally not necessary to set the LED screen
parameters (including LED The screen size and the network port parameters);
If you have previously set up an archive, you can complete the "LED screen parameter" data
synchronization through the PC control software "import \ export configuration";
The width and height of each network port must be the same as the local size of the LED screen
covered by the interface card actually carried by each network port. By changing the starting position
of each network port, the LED screen can be arbitrarily spliced (each Gigabit of the network port can
display any part of the screen or repeat it);
Pay attention to the size range of the LED screen and the total load points of the LED screen:
LED screen horizontal width <= 8000
Vertical height of LED screen <= 3840

WIN7 computer graphics card can automatically read the recommended EDID resolution of
the input DVI / HDMI port of the device. Output recommended resolution; after WIN10
input resolution setting is completed, you must manually select "Recommended
Resolution" on the computer.
By setting the input resolution, users can realize the input and output point-to-point
display of the ultra-high-resolution LED large screen within the range of 3840x2160. The
point-to-point display does not scale the input image, so the display image on the LED
large screen can reach the highest definition degree.

Horizontal width: adjustment range 640-3840
Vertical height: adjustment range 480-2160
Refresh rate: adjustment range 30 or 60
Note:
The actual adjustment range is not related to the interface type and the input bandwidth
limitation. For this device, because the standard used by the system's input source DP is
DP1.2, it can reach the highest 4K level input resolution: 3840x2160 @ 60Hz; HDMI uses the
standard It is HDMI1.4, so it can reach the highest 4K input resolution: 3840x2160 @ 30Hz.
