5. Operation Instructions
5.1 Input Settings
For digital input interfaces like DVI, HDMI, and DP, you can directly set and change the resolution. For other input methods, resolution changes must be made on the input devices. There are two ways to set input resolution:
Method One: Preset Resolution
Choose from the controller’s preset resolutions. If the desired resolution isn’t available, proceed to customize it.
Method Two: Custom Resolution
Manually set the Horizontal and Vertical resolution along with the refresh rate. Afterward, select “Apply” and press the knob to confirm.
5.2 Screen Settings
For shortcut screen settings, the screen and cabinets must be regular rectangles with identical sizes.
Step 1: Ensure the screen is powered on. If the cabinets display normally, proceed to Step 2. If not, load the cabinet file and save it to the receiving card. Refer to Advanced Settings for details.
Step 2: Go back to the “Screen Settings” submenu. Rotate the button to navigate through the submenus and configure the settings.
Step 3: Adjust the Cabinet Row Qty and Cabinet Column Qty based on the screen’s actual layout.
Step 4: Set the Port1 Cabinet Qty, keeping in mind the device’s limitations on the number of cabinets per port.
Step 5: Define the Data Flow (Front View).
5.3 Brightness Settings
Go back to the main menu. Press the Knob to choose the Brightness Setting. Then, rotate the knob to adjust the brightness value.
5.4 Output Settings
Output settings are divided into three cases:
Disable Scaling: The output image matches the input image size, preserving the original scale. If the input resolution is smaller than the LED display in any direction, that part may remain unlit. If larger, some content may be cut off. This setting is ideal for point-to-point display scenarios. You can adjust the horizontal and vertical offsets to reposition the content on the screen.
Auto Fit: When [Scaling] is turned on, [Auto Fit] automatically adjusts the input content to fully cover the LED display, making it ideal for full-screen content playback.
Custom Scaling: In this mode, [Scaling] is active, but [Auto Fit] is disabled, allowing for manual scaling adjustments.
For custom scaling, follow these steps:
Step 1: Adjust the input capture by selecting a portion of the input image to display on the LED screen, starting from a specific point. Set the Horizontal and Vertical Resolution (which should not exceed the input source’s resolution) along with Horizontal X and Vertical Y coordinates.
Step 2: Configure the Output Window, ensuring its size is within or equal to the LED display dimensions. The content will fit within this window, which is useful for scenarios requiring a border or restricted playback area on the LED display.
Once you’ve completed the two steps above, the captured content will be displayed solely within the specified area on the LED screen, as illustrated below:
