H_4XDVI INPUT CARD | Carte d'Entrée Quadruple DVI Dual Link Novastar H

The H_4XDVI INPUT CARD by Novastar is a high-performance modular expansion board designed specifically for the H Series Video Wall Processors, including the H2, H5, and H9 chassis. This enterprise-grade input card features four Dual Link DVI ports, providing robust connectivity for professional video sources and workstations. By utilizing Dual Link technology, this card surpasses standard Full HD limitations, supporting resolutions up to 2560×1600 per port. This makes it an indispensable component for high-fidelity data visualization where clarity and pixel accuracy are paramount.

As part of Pixelight’s curated professional range, this card ensures seamless integration within 4K and 8K LED display ecosystems. It allows for the simultaneous ingestion of four discrete digital signals or the synchronization of inputs for ultra-high-resolution mosaics. The card’s architecture is optimized for low-latency processing, ensuring that high-refresh-rate content remains fluid and synchronized across large-scale LED video walls, maintaining the high contrast ratio and color depth required for modern visual installations.

Pro-Grade Signal Processing and Hardware Reliability

In the world of high-end LED displays, the quality of the signal chain is just as critical as the Nit brightness or the SMD binning of the LEDs. The H_4XDVI card leverages Novastar’s advanced hardware processing to maintain signal integrity from source to screen. Unlike consumer-grade interfaces, these Dual Link DVI inputs are engineered for stability in 24/7 environments like command centers and broadcast studios.

Why DVI Dual Link Matters for Fine-Pitch LED

When working with fine-pitch LED displays (P0.9 to P1.5), pixel-perfect mapping is essential. The H_4XDVI supports higher bandwidth than single-link cards, allowing for increased refresh rates and higher resolution capacity without compression artifacts. This ensures that the high-contrast ratio and wide viewing angles of premium GOB (Glue on Board) or SMD LED panels are fully utilized by delivering a pristine digital signal.

• Hot-Swappable Design: Modular architecture allows for site maintenance or upgrades without powering down the entire processor.
• High Density: Save valuable slot space in your H-Series chassis by managing four high-resolution sources on a single card.
• EDID Management: Sophisticated EDID control ensures the graphics workstation properly recognizes the LED wall's custom resolutions.

Versatile Deployment for Global Visual Projects

The H_4XDVI Input Card is a versatile solution for diverse professional industries where multi-source monitoring is a core requirement. Its ability to handle multiple digital inputs at high resolution makes it a favorite for system integrators across Europe and beyond.

• Command and Control Rooms: Connect multiple monitoring stations or server outputs to a central LED video wall for real-time data analysis.
• Corporate Data Walls: Ideal for boardroom installations where high-resolution charts and financial data require pixel-perfect clarity.
• Broadcast Facilities: Use the four inputs to monitor multiple studio feeds or playout channels simultaneously with zero latency.
• Large-Scale Events: Perfect for rental environments where various legacy PC sources and media servers must be integrated into a unified H-Series processing system.

Technical Implementation and Setup Guidance

For optimal performance with your H_4XDVI Input Card, Pixelight’s technical team recommends following professional signal management standards. Ensure your DVI cables are high-quality copper or active optical cables (AOC) if exceeding 5 meters to prevent signal degradation and electromagnetic interference.

• Resolution Matching: Configure your source workstation to match the native resolution of your LED wall to avoid unnecessary scaling, which preserves the sharpness of fine-pitch SMD displays.
• Power Management: Utilize the hot-swappable feature carefully; ensure the locking screws are tightened to maintain a solid connection to the backplane, preventing power surges or data loss.
• Controller Sync: When using multiple inputs for a mosaic, utilize the H-Series internal clock synchronization to ensure perfect frame-sync across all four DVI inputs.
• Maintenance: Periodically check the DVI pins for oxidation and ensure the chassis environment is dust-controlled to maintain optimal thermal dissipation.
