If you manage an LED display for presentations, events, or digital signage, you’ve likely dealt with a complex setup: a media player for content, a separate sending card to drive the screen, extra cables, and often a dedicated computer. The Novastar TU4K Pro is designed to consolidate all of that into a single, powerful device.

At its core, NovastarTU4K Pro LED processor is an all-in-one control unit that combines three critical functions:

• A Media Player: It runs on Android 13, allowing you to install apps, browse the web, and play content directly.
• A Video Processor: It handles multiple high-resolution inputs (like HDMI from your laptop), scales and optimizes the image, and manages complex screen layouts.
• An LED Sending Card: It directly outputs the signal to your LED display modules via its 20 Gigabit Ethernet ports, eliminating the need for a separate sending card.

In simple terms, the Novastar processor TU4K Pro is the brain and the nerve center for your LED screen. It takes content from various sources, processes it, and ensures it displays perfectly across your entire display wall. This integration makes it an ideal solution for users who want professional-grade performance without the complexity of managing multiple devices—perfect for corporate boardrooms, university lecture halls, retail showrooms, and event venues.

Connect up to three external sources (1× HDMI 1.3 + 2× HDMI 2.0) and use the internal Android 9.0 system as a fourth source—ideal for switching between a laptop, media player, and local apps without extra hardware.

Drive high-resolution LED walls up to 3840×2160@60Hz with support for up to 4 million pixels per link, ensuring sharp, seamless visuals even on large displays.

Mirror content wirelessly from Windows, macOS, iOS, and Android devices directly to the screen—no dongle required (though USB wireless adapters are supported for extended compatibility).

Automatically enhance picture quality using AI Image Enhancement, which reduces noise and sharpens edges. Choose from four preset modes—Standard, Meeting, Vivid, and Skin—to match your environment or content type.

Operate the TU4K Pro via the front-panel LCD, included infrared remote, or mobile apps (ViPlex Handy and VNNOX Care) over Wi-Fi or Ethernet. RS232 support also enables integration with third-party control systems.

Easily adjust output scaling, aspect ratio, and positioning through intuitive menus to perfectly fit your LED screen.

Connecting your LED display to the Novastar TU4K Pro is a straightforward process. This section provides a clear, step-by-step guide to establish a reliable physical link between the processor and your screen.

Locate the 20 numbered Gigabit Ethernet (RJ45) output ports on the rear panel of your TU4K Pro LED processor. These are your primary ports for sending data to the LED cabinets.

Use standard CAT5e (or higher) Ethernet cables. For longer runs or to avoid electrical interference, you can utilize the two OPT fiber optic ports with compatible optical modules and fiber cables.

Connect one end of an Ethernet cable to an output port (e.g., Port 1) on the Novastar processor. Connect the other end to the first receiving card in your LED cabinet array. Repeat this process, connecting Port 2 to the next cabinet in the chain, and so on.

The data flow typically starts from the cabinet connected to Port 1. Ensure your physical cabinet layout matches the intended configuration in the processor’s software for a correct image.

Plug the TU4K Pro into a power outlet using the provided cable. Connect your content sources (e.g., a laptop via HDMI, a USB drive) to the corresponding input ports on the rear panel.

Once your Novastar TU4K Pro is connected and powered on, the next critical step is to tell the processor exactly how your LED cabinets are arranged. This process, known as screen configuration or mapping, ensures the input image is correctly spread across your entire display.

Before you start, enable a helpful visual aid:

• Navigate to LCD Menu > Screen Configuration > Mapping and turn it On.
• This function makes each cabinet temporarily display its Ethernet Port number and Receiving Card ID.

For a grid of identical cabinets connected in order, the Quick Configuration tool automates the setup.

• Go to LCD Menu > Screen Configuration > Quick Configuration.
• Enter the basic parameters of your screen:

Cabinet Row Qty / Column Qty: The grid size (e.g., 2 rows by 3 columns).
Port 1 Cabinet Qty: How many cabinets are connected to the first Ethernet port.
Data Flow: Select the direction the signal travels across the cabinets (e.g., from left to right, top to bottom).

• The Novastar processor will then calculate and apply the configuration. Your full screen should now display a single, unified image.

This is a crucial step to ensure persistence.

• After configuring the layout and scaling, go to Screen Configuration > Save to Hardware.
• Confirm the action. This permanently saves the settings to the TU4K Pro’s internal memory.
• Benefit: Your screen will now boot up correctly every time, even after a power cycle, without needing reconfiguration.

Imagine a 3×3 video wall in a boardroom. You would:

• Use Mapping to confirm all 9 cabinets are detected and in the right order.
• Use Quick Configuration to set Rows=3, Columns=3, and define the data flow.
• Use Scaling to ensure a guest’s laptop presentation fills the entire video wall seamlessly.
• Save to Hardware so the layout is ready before every meeting.

Successfully configuring the screen layout unlocks the full potential of your Novastar Processor. With the display correctly mapped, you can now focus on fine-tuning the image quality, which we will cover in the next section on adjusting brightness, color, and display modes.

After configuring your screen layout, the next step is to fine-tune the image to achieve the perfect visual output for any type of content. The Novastar TU4K Pro provides intuitive, multi-layered controls for adjusting brightness, color, and display modes, making it easy to optimize the picture for a boardroom presentation, a vibrant video, or a video conference.

For quick, essential adjustments without entering the full system, use the front-panel LCD menu. Press the knob on the TU4K Pro LED processor to enter the Main Menu:

• Adjusting Brightness: Navigate to Screen Brightness (%). Rotate the knob to increase or decrease the overall brightness and press to confirm. This is crucial for matching the screen brightness to ambient room lighting.
• Adjusting Volume: Select Volume and rotate the knob to control the system’s audio output level.

The Novastar processor includes several preset display modes designed for specific content types. Access these via LCD Menu > Effects > Mode or in the Settings app.

• Standard Mode: The balanced default setting, suitable for general use and mixed content.
• Meeting Mode: Optimized for clarity and reduced eye strain. It enhances text and graphic sharpness, making it ideal for PowerPoint presentations, spreadsheets, and documents.
• Vivid Mode: Boosts color saturation and contrast, delivering a more dynamic and engaging picture perfect for video playback, advertisements, and promotional content.
• Skin Tone Mode: Calibrated to render human skin tones naturally and accurately, ensuring participants look their best during video conferences or live broadcasts.
• Eye Comfort: An option within the mode menu that adds a warmer, yellowish tint to the display to reduce blue light exposure during prolonged viewing sessions.

For further customization, delve into the Advanced settings under Effects or the Display and Effects system menu.

• Manual Color Controls: Adjust parameters like Contrast, Saturation, Color Temperature (warm/cool balance), and Hue to match your precise preferences or brand colors.
• AI Image Enhancement: Enable this intelligent feature (Effects > Advanced) to allow the TU4K Pro LED Playback Control Processor to analyze each frame in real-time. It automatically enhances sharpness, optimizes colors, and applies dynamic motion compensation for a consistently superior picture.
• HDR (High Dynamic Range): For compatible HDR10 content from HDMI sources or the Android system, enabling HDR (Video Source Settings > HDR) unlocks greater contrast between the brightest whites and darkest blacks, revealing more detail in shadows and highlights.

• Starting a Business Presentation: Switch to Meeting Mode and slightly increase brightness if the room is well-lit.
• Playing a Promotional Video: Select Vivid Mode and ensure AI Image Enhancement is turned on for maximum impact.
• Hosting a Video Call: Activate Skin Tone Mode to ensure natural-looking participants.
