Part Two How to get a quick start with NovaStar VX4S
Firsrt: Input Settings
Method I: Preset Resolution
Selection is made in the preset resolution of the controller. You can select the second method and customize the resolution if there is no preset 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, the custom resolution is invalid.
Second: Screen Settings
Step 1
The screen is power-on, if the cabinet is in the normal display, enter 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 the 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).
Third: 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.
Fuorth: Output Settings
Output settings are divided into three cases:
Case 1 Disable Scaling
The sizes of the output image and input image are the same, and the original scale output is used.
If the input resolution is smaller than the LED display in one direction, the 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 applies 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.
case 2 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.
case 3 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 the input source),
Vertical Res (smaller than or equal to the vertical resolution of input source), horizontal X, and vertical Y.
✓Step 2 Set the output layer, the size of the layer is smaller than or equal to the size of the LED display;
After setting the layer, the images can only be adaptive to the display size within the range of the layer.
This option is applicable to the application scenarios requiring reserving a border at the LED display or restricting the 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
