MX_4XHDMI 2.0 INPUT CARD | Carte d'Entrée Quadruple HDMI 2.0 Novastar | 4K @ 60Hz

The Novastar MX_4XHDMI 2.0 Input Card is a high-performance expansion module designed for the MX Pro series controllers. Specifically engineered for professional LED display integration, this card features four independent HDMI 2.0 ports, allowing for the simultaneous connection of multiple UHD sources. Whether you are managing complex video layers or requiring a robust 4K interface, this card delivers uncompressed signal integrity for mission-critical visual applications.

By supporting resolutions up to 4096x2160 at 60Hz across all four ports, it eliminates motion blur and ensures every pixel on your LED wall—regardless of the pitch—remains sharp and fluid. Its hot-swappable architecture allows for seamless hardware upgrades and maintenance without powering down the main processor, ensuring 24/7 reliability for permanent installations and high-stakes live events.

Professional Signal Management and Architecture

As a technical cornerstone for modular LED systems, the MX_4XHDMI 2.0 Input Card is built to handle the rigorous bandwidth requirements of modern LED displays. With a focus on signal stability, each port supports a high refresh rate of 60Hz at 4K resolution, which is critical for maintaining visual synchronization and preventing tearing on large-scale LED canvases.

Enhanced Bit Depth and Color Accuracy

Beyond simple resolution, this card supports advanced color processing. When paired with high-quality SMD or GOB LED modules, it helps maintain a high contrast ratio and wide viewing angles by ensuring the source signal remains pristine. The card’s ability to handle HDR content and various bit depths allows the LED processor to maximize the grayscale performance of the display, resulting in smoother gradients and more lifelike imagery.

Scalability and Splicing Technology

The card supports internal mosaicing (splicing), allowing users to combine multiple 4K inputs into a massive digital canvas. This is particularly effective for displays with a fine pixel pitch where the total pixel count exceeds standard UHD limits. The hardware-level processing reduces latency, ensuring that even with multiple layers and windows, the refresh rate remains consistent across the entire screen surface.

Versatile Deployment Scenarios

The MX_4XHDMI 2.0 Input Card is a versatile tool for various high-end LED environments:

• Control Rooms: Ideal for monitoring multiple high-definition data feeds simultaneously, providing operators with a seamless view of critical information across a large LED mosaic.
• Live Concerts and Broadcasting: Enables the intake of four 4K camera feeds or media server outputs, allowing for complex multi-layer compositing on stage backgrounds with zero downtime.
• Corporate Experience Centers: Perfect for installations using GOB technology or fine-pitch LEDs where high-impact visuals and multiple presentation inputs are required.
• Retail Flagships: Powers ultra-wide digital signage displays by splicing multiple 4K sources to cover non-standard aspect ratios without losing image clarity or nits brightness performance.

Technical Optimization and Maintenance

To achieve the best performance from your MX_4XHDMI 2.0 card, we recommend the following expert tips:

• Cable Selection: Always use certified HDMI 2.0 Premium High-Speed cables for distances under 5 meters. For longer runs, utilize active optical cables (AOC) to prevent signal degradation and maintain 4K @ 60Hz stability.
• Hot-Swapping Protocol: While the card is hot-swappable, always ensure the locking screws are fully engaged to prevent vibration-induced signal loss, especially in touring or rental environments.
• EDID Management: Utilize the Novastar V-Can or MX series software to customize the EDID (Extended Display Identification Data) for each port. This ensures your media servers output the exact native resolution of your LED wall, optimizing the pixel-to-pixel mapping.
• Cooling: Ensure the main controller chassis has adequate airflow, as processing four simultaneous 4K streams generates significant thermal output.
