H_4×DVI OUTPUT CARD | Carte de Sortie Quadruple DVI Dual Link Novastar H

The Novastar H_4×DVI Output Card is a high-performance expansion module engineered for the versatile H Series Video Wall Processors, including the H2, H5, H9, and H15 chassis. This professional-grade card features four Dual Link DVI output ports, providing a robust solution for auxiliary monitoring and localized video distribution. By leveraging Dual Link technology, the card supports high-bandwidth signals, enabling resolutions up to 2560×1600 @ 60Hz, ensuring that your preview and reference monitors maintain exceptional clarity and color accuracy.

Designed for mission-critical environments, this card allows system integrators to bridge the gap between cutting-edge LED processing and traditional DVI-based infrastructures. Its hot-swappable architecture ensures seamless integration and maintenance without downtime. Whether you are managing complex pixel maps or requiring dedicated confidence monitors for live events, the H_4×DVI card delivers reliable, low-latency signal transmission with the professional stability expected from Novastar’s flagship hardware.

Professional Signal Integrity and Modular Engineering

Advanced DVI Dual Link Capability

In the world of high-end LED displays, maintaining signal integrity from the processor to the monitoring station is paramount. The H_4×DVI Output Card utilizes Dual Link DVI technology, which effectively doubles the bandwidth compared to single-link interfaces. This is crucial for maintaining high refresh rates and preventing motion blur on high-resolution reference monitors. While standard DVI is often limited, these Dual Link ports allow for a pixel clock frequency that supports large-scale canvas monitoring without compression artifacts.

Hot-Swappable Reliability for H-Series Chassis

Pixelight recommends this module for environments where uptime is non-negotiable. The card’s hot-swappable design means it can be added or replaced while the H-series processor is powered, ensuring that your primary LED wall’s SMD or GOB modules continue to receive data uninterrupted. Each output is independently configurable within the Novastar H-Series web interface, allowing for precise control over the output timing and EDID management. This level of granular control is essential for matching the color gamut and brightness of auxiliary LCD screens with the main LED video wall, ensuring visual consistency across the entire control room suite.

Versatile Deployment Scenarios

The H_4×DVI Output Card is a staple in diverse professional AV environments:

• Broadcast Control Rooms: Ideal for feeding confidence monitors and multiviewer displays, allowing directors to see the processed signal before it hits the main LED screen.
• Fixed Installations & Retail: Great for systems that utilize legacy DVI distribution amplifiers or existing LCD video walls alongside newer LED technology.
• Live Events & Concerts: Used by technicians at the Front of House (FOH) to monitor the 1:1 pixel output of the LED wall, ensuring that high-refresh-rate content is playing smoothly.
• Command and Control Centers: Provides specialized outputs for operator workstations where high-resolution data visualization is required on localized desktop monitors.
• Corporate Auditoriums: Facilitates the connection to legacy projection systems or auxiliary DVI-based displays in overflow rooms.

Technical Implementation & Optimization Tips

To maximize the performance of your Novastar H_4×DVI Output Card, consider the following expert advice:

• Cable Quality and Distance: DVI signals are sensitive to distance. For resolutions exceeding 1920x1200, ensure you use high-quality, shielded Dual Link DVI-D cables. For distances over 15 meters, consider active DVI extenders to prevent signal degradation or "sparkle" artifacts.
• EDID Management: Utilize the H-series software to customize the EDID (Extended Display Identification Data) for each port. This ensures the output card matches the native resolution and refresh rate of your specific monitor, avoiding scaling issues.
• Thermal Management: When populating a H9 or H15 chassis with multiple output cards, ensure the rack's ventilation is unobstructed. Maintaining an optimal operating temperature extends the lifespan of the internal capacitors and signal processors.
• Firmware Synchronization: Always ensure the output card firmware is synchronized with the main H-series controller firmware to unlock the latest features and stability patches.
