7 Operation instruction
The functions of VX4 are powerful with very simple operations, and multiple operations can be completed with a knob and return keys The design of more than one shortcut keys makes operations more efficient.

Generally, the LED display can be used normally, and the brightness is moderate after conducting the following four steps: Input settings → Screen settings → Brightness → Output settings Other menus such as screen control and senior setting can help users better control LED displays LTD.

See the following section for details of operationss.

Step1: Input Settings
Set resolution of input source 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 in two methods:
Method one: Preset Resolution
Selection is made in preset resolution of the controllers If there is no preset resolution, you can select the second method and customize resolution.
Method two: Custom Resolution
Set Horizontal Res, Vertical Res, and Custom· refresh rate and then select “Apply” and press the knob for application. If the application is not confirmed, custom resolution is invalid.

Step2: Screen Settings
The precondition of the Screen setting in the shortcut is that the screen must be a regular rectangle (not special-shaped), the cabinet must be a regular rectangle and the size of each cabinet are identical
Step 1 The screen being power-on, if the cabinet is in the normal display, enter into Step 2; if the cabinet is in the abnormal display, first, load the cabinet file, and save it to the. receiving card; see the detailed operation in Advanced Settings ;
Step 2 Return to the “Screen Settings” submenu Rotate the button to switch to submenus of other options respectively to perform configurations, as shown in the following figures:

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;
Step 5 Set the Data Flow (Front View)s Pay attention to precautions for screen 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 screens, the NovaLCT-Mars software is required to be connected to configure the screen.
   （c ）During the 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 the 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 the Data Flow setting, you must ensure that the data flow of each port is downward in the same direction.
   （e ）During the Data Flow setting, you must ensure that Port 1 is the start position of the whole data flow connection.

VX4 can load 2.3 million (2048×1152@60Hz) pixels in maximum. The width of lateral load can reach 3840 pixels in maximum (3840×600@60Hz); the longitudinal load can reach to 1920 pixels in maximum (1920 x1200@60Hz).
Setp3: Brightness
Return to the main menu interface Press the Knob to select the corresponding value of Brightness You can rotate the Knob to adjust the value at this time.
Setp4: Output Settings
Output settings are divided into three cases:
First one: disable Scaling, i the sizes of the output image and input image are the same, and original scale output is used If the input resolution is smaller than the LED display in one direction, LED display may not become bright in this direction; if the input resolution is greater than the LED display in one direction, the input contents may not be displayed completely in this direction This option is applicable to the application scenarios requiring point-to-point display Horizontal offset and vertical offset of images can be set according to the needs, and at this time the displayed contents may move to the left or top at the LED display this point [Scaling] is disabled
Second one: AutoFit At this point [Scaling] is enabled, and [Auto Fit] is enabled When enabling [Auto Fit], the input contents will be fully zoomed to the size of LED display, and the input contents will be adaptive to the size of LED display This mode is suitable for full-screen playback of the contents Third one: Custom Scaling At this point [Scaling] is enabled, while [Auto Fit] is disabled The following steps should be performed for custom scaling: Step 1 Set the input Capture, capture part of the interesting screens from one starting point of inputting image and display it on LED display It is generally required to set Horizontal Res (smaller than or equal to the lateral resolution of input source), Vertical Res (smaller than or equal to the vertical resolution of input source), horizontal X and vertical
Step 2 Set output window, the size of the window is smaller than or equal to the size of LED display; after setting the window, the images can only be adaptive to the displayed size within the range of window This option is applicable to the application scenarios requiring reserving border at the LED display or restricting playing area.
After setting according to the above two steps, the captured contents will only be input and displayed at the settings area on the LED display, as shown below:

Image Mosaic
When the display screen is huge, two or more VX4 need to be cascaded for loading the huge screen;

Choose the method of Image Mosaic: Equal Division, Unequal Division

• Equal Division: Each VX4 has the same load area It is only required to set total pixel points, rows, columns of the big screen, and the serial No of each VX4
• Unequal Division: Each VX4 could have a different load area  It is required to set the total pixel points and the load area size, as well as load area, starting position of each.

Image Mosaic example: The total number of pixels of LED display is 3000×1000, exceeding the load capacity of a single VX4. Two sets of VX4 are used for Image
Mosaic processing. The connection method is shown in the right figure.
Please choose Equal Division or Unequal Division while setting detailed parameters The specific parameter settings are shown in the following tables.

Equal Division|
---|---
| VX4（1） VX4（2）
Total Width Pixels| 3000
Total Height Pixels| 1000
Mosaic Row| 1
Mosaic Column Qty| 2
Load Area Position 1| 2
