6 Menu Operations
The functions of the VX4S-N 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 efcient.
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.
Step 1: 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 I: Preset Resolution.

Step 2: 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, rst, load the cabinet le, 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 congurations, as shown in the following

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:

VX4S-N User Manual

(a) If the number of ports with
loads is n (n≤4), the rst 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, dierent cabinet sizes and special-shaped
screen, the NovaLCT-Mars software is required to be connected to congure the screen.
(c) During Data Flow setting, you can rotate the button to see the eects of dierent data
ow on the screen in real time. If you are satised with the eect of current data ow,
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 ow connection.
The VX4S-N 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 (1200x1920@60Hz).
Step 3: 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.

Step 4: 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 VX4S-N units need to be cascaded for
loading the huge screen;
Choose the method of Image Mosaic: Equal Division, Unequal Division.
Equal Division: Each VX4S-N 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 VX4S-N.
Unequal Division: Each VX4S-N 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
VX4S-N.
Image Mosaic example: The total number of pixels of LED display is 3000×1000,
exceeding the load capacity of single VX4S-N. Two sets of VX4S-N are used for Image
Mosaic processing. The connection method is shown in the right gure.

Custom, Left Top, Left Bottom, Right Top etc. When choosing any mode except Custom ,
the values of horizontal and vertical offset of PIP are able to adjust to the corresponding
values of layout automatically. The meaning of each layout mode is shown below:
Custom refers to that the size and position of PIP need to be set.
Left Top, Left Bottom, Right Top, Right Bottom, Center refer to that PIP overlaps with
the top-left corner, bottom-left corner, top-right corner, bottom-right corner and center of
main layer.
Top Bottom, Left Right refer to that main layer and PIP are distributed from top to
bottom or left to right.
Main source/PIP source: Input source switching of main layer and PIP is the same as the
role of input source switching on the front panel.
Horizontal Res : Horizontal offset of PIP
Vertical Res : Vertical offset of PIP
Horizontal X : Horizontal width of PIP
Vertical Y : Vertical height of PIP
PIP Crop Settings: Picture is cropped from the set starting position and is displayed on PIP
and its size is set horizontal width and vertical height.
Enable this function and then set horizontal width, vertical height, horizontal X and vertical Y.
