7 Operation Instruction

VX4U has powerful functions and is easy to operate. All operations can be completed T through a knob and a return key. The design of shortcut keys makes the operations S more efficient.Generally, LED display can work normally, and the brightness is moderate after V 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. N 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:

Method I: Preset Resolution.Selection is made in preset resolution of the controller. If there is no preset resolution, you can select the second method and customize resolution.

Method II: 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 Screen setting in shortcut is that the screen must be regular C rectangle (not special-shaped), cabinet must be regular rectangle and the size ofeach 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 TE save it to the receiving card; see 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 TA 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 I ‘quantity of ports. For details, see precautions for screen settings;

5 Set the Data Flow (Front View). 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 screen, ., the Novato-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 TE 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 (2048×) pixels in maximum. The width of lateral load can T reach to 3840 pixels in maximum (3840×); the longitudinal load can reach to 1920 S pixels in maximum (1920 ).

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.e., the sizes of 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.At this point [Scaling] is disabled.

Second one: Auto Fit. At this point [Scaling] is enabled, and [Auto Fit] is enabled. TA When enabling [Auto Fit], the input contents will be fully zoomed to the size of LED S display, and the input contents will be adaptive to the size of LED display. This mode A is suitable for full-screen playback of the contents.Third one: Custom Scaling At this point [Scaling] is enabled, while [Auto Fit] is O disabled.

The following steps should be performed for custom scaling:Step 1 Set the input Capture, i.e., 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 X of input source), Vertical Res (smaller than or equal to the vertical resolution of input source), horizontal X and vertical Y.

Step 2Set output window, the size of 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 LT input and displayed at the set area on the LED display, as shown below:

Image Mosaic

When the display screen is huge, two or more VX4U need to be cascaded for loading the huge screen;Choose the method of Image Mosaic: Equal Division, Unequal Division.

• Equal Division: Each VX4U has same load area. It is only required to set total pixel points, rows ,columns of the big screen and the serial No. of each VX4U.
• Unequal Division: Each VX4U could have different load area . It is required to set the total pixel points and the load area size as well as load area staring position N of each VX4U.

Image Mosaic example: The total number of pixels of LED display is 3000×1000, exceeding the load capacity of single VX4U. Two sets of VX4U are used for Image Mosaic XI’A processing. The connection method is shown in the right figure.

Please choose Equal Division or Unequal Division while setting detailed parameters. L The specific parameter settings are shown in the following tables.

Advanced Settings

Several setting options of main functions are included in advanced settings, as A shown in the figure below. Operation of each function will be detailed for users in V the following text.
