7 Operation Instruction

VX4U has powerful functions and is easy to operate. All operations can be completed

through a knob and a return key. The design of shortcut keys makes the operations

more efficient.

Generally, LED display can work normally, and the brightness is moderate after

following four steps: Input Settings → Screen Settings → Brightness → Output

Settings. Other menus such as display control and advanced settings can help users

better control the LED display.

See the following section for detailed operation.

Step1: Input Settings

Set resolution of input signal. Resolution can be directly set and changed for digital

input interfaces DVI, HDMI and DP. Resolution can only be modified with other input

methods on input devices.

Input resolution can be set through two methods:

rectangle (not special-shaped), cabinet must be regular rectangle and the size of

each cabinet are identical.

Step 1 The screen being power-on, if the cabinet is in normal display, enter into

Step 2; if the cabinet is in abnormal display, first, load the cabinet file, and

save it to the receiving card; see detailed operation in Advanced Settings ;

Step 3 Set Cabinet Row Qty and Cabinet Column Qty according to the actual

situation of the screen;

Step 4 Set Port1 Cabinet Qty. The device has some limitations on the cabinet

quantity of ports. For details, see precautions for screen settings;

settings c), d) and e) below.

Precautions for screen settings:

（a）If the number of ports

with loads is n (n≤4), the first

n-1 ports must load the same

number of cabinets, which must

also be an integral multiple of

the number of cabinet rows or

columns and be greater than or

equal to the number of cabinets

for the nth ports.

Example:

For example, if port 1, port 2, port 3 have loads,

port 1 and port 2 must have the same number of

cabinets, which must also be an integral multiple

of the number of cabinet rows or columns.

Therefore, you only need to set port 1 cabinet Qty

according to the actual situation when setting the

screen. The number of receiving cards port 3 loads

must be smaller than or equal to port 1.

（b）In the case of special-shaped cabinets, different cabinet sizes and special-

shaped screen, the NovaLCT-Mars software is required to be connected to configure

the screen.

（c）During Data Flow setting, you can rotate the button to see the effects of

different data flow on the screen in real time. If you are satisfied with the effect of

current data flow, you must press the button to save the setting. You can press the ESC

to exit from the current operation.

（d）During Data Flow setting, you must ensure that the data flow of each port is

downward in the same direction.

（e）During Data Flow setting, you must ensure that Port 1 is the start position of the

whole data flow connection.

VX4U can load 2.3 million (2048x1152@60Hz) pixels in maximum. The width of lateral

load can reach to 3840 pixels in maximum (3840x600@60Hz); the longitudinal load

can reach to 1920 pixels in maximum (1920 x1200@60Hz).

Setp3: Brightness
