7 Operation instruction
The functions of VX4 are powerful with very simple operation, and multiple
operations can be completed with a knob and a return key. 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 display.
See the following section for details of operations.
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 controller. If there is no preset
resolution, you can select the second method and customize resolution.

Step2: Screen Settings
The precondition of Screen setting in shortcut is that the screen must be regular
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 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:

Screen Settings
Output 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;
Step 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 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.
VX4 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).

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.
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, 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
of input source), Vertical Res (smaller than or equal to the vertical resolution
of input source), horizontal X and vertical Y.

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 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.
Xi’an NovaStar Tech Co., Ltd.

VX4S/VX4 User's Manual

Unequal Division: Each VX4 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
of each VX4.
Image Mosaic example: The total number of pixels of LED display is 3000×1000,
exceeding the load capacity of 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.
