After preparing the required equipment, the next step is to connect the HUIDU HD-VP1240A LED video processor to the LED display system. A typical connection involves three parts: the signal source, the processor, and the LED screen.

On the rear panel, connect your video sources:

• HDMI 1 (4K@60Hz), HDMI 2/3 (4K@30Hz), DP (4K@60Hz), Type-C (4K@60Hz, shared with DP), or DVI 1/2 (1080p@60Hz).
• For audio from these sources, it’s embedded automatically. If you need separate analog audio, connect a 3.5mm cable to AUDIO IN.
• Type-C and DP cannot be used simultaneously; default is DP. Enable Type-C in [Advanced Settings].

Use Ethernet cables to connect the 12 Gigabit Ethernet output ports on the HD-VP1240A video wall processor to the receiving cards installed in your LED cabinets. These network ports transmit the processed video signal directly to the display modules. Each port supports up to 650,000 pixels.

If you need sound from the processor, connect a 3.5mm cable from AUDIO OUT to your amplifier or powered speakers.

Connect a computer to the processor using a USB-B cable. This computer will run HDSet software for screen configuration and system control. You can also connect via RS232 for central control systems if needed.

Attach the included Wi-Fi antenna if you plan to use wireless control. Then connect the power cable to the AC input and plug it into a power outlet. Press the front panel switch to power on the unit. The LCD display should light up showing the current status.

Before you can configure your LED screen, you need to install the HDSet software on your computer. HDSet is the official PC software for the HD-VP1240A that allows you to adjust screen parameters, set up multi-window layouts, and manage scene presets.

• Step 1: Get the software from the included CD or download the latest version from the HUIDU technical support website.
• Step 2: Open the software package and select your preferred language for installation. Click [OK] to proceed.
• Step 3: An installation wizard will appear. Click [Next] to continue. Choose the installation location (click [Browse] to change the default folder if needed), then click [Install] to begin the installation.
• Step 4: Wait for the installation to finish. Once done, HDSet is ready to use on your computer.
• Step 5:Use a USB-B cable to connect the HD-VP1240A video wall processor to your computer. This connection allows HDSet to communicate with the processor for screen configuration and real-time adjustments.

Once installed, HDSet gives you full control over the HD-VP1240A’s features:

• Screen Configuration: Set up your LED display with up to 16000 pixels width and 4000 pixels height.
• Network Port Assignment: Configure the 12 Gigabit Ethernet ports, each supporting 650,000 pixels.

Enter your LED screen’s total width and height in pixels. Maximum width is 16000 pixels, maximum height is 4000 pixels. Total pixels (width × height) cannot exceed the 7.8 million pixel loading capacity of this video wall processor. For example, 3840×1800 (6.9M) works, but 3840×2160 (8.3M) exceeds the limit.

HD-VP1240A has 12 Gigabit Ethernet ports for connecting to receiving cards. Each port supports up to 650,000 pixels. For each port:

• Set the X (horizontal start) and Y (vertical start) positions
• Define the output area by setting width and height
• Ensure start position + size does not exceed total screen dimensions
• Total pixels assigned across all ports must match your screen size

Click [Apply] to save settings to the processor. Use test patterns or play content to confirm the display works correctly.
