NOVASTAR VX400 PRO | Contrôleur LED Tout-en-Un 4K | 2,6 Millions de Pixels

The Novastar VX400 PRO is a high-performance, all-in-one LED display controller designed to streamline signal processing and screen management. With a robust loading capacity of up to 2.6 million pixels, it serves as an ideal solution for small to medium-sized LED projects requiring high-definition clarity. This professional-grade unit combines the capabilities of a high-end video processor with an integrated sending card, all contained within a compact 1U rack-mountable chassis. It supports input resolutions up to 4K@60Hz via HDMI and DisplayPort, ensuring that your content maintains exceptional detail and fluid motion regardless of the pixel pitch of your LED modules.

Built for reliability and ease of use, the VX400 PRO features four Gigabit Ethernet output ports for stable data distribution. It offers advanced video processing features, including low-latency technology and multi-layer management, which are essential for professional live events and high-end fixed installations. Whether you are managing an SMD indoor screen or a high-brightness outdoor display, this controller ensures consistent image quality and professional-grade performance.

Professional Grade Signal Processing and Reliability

As a leading wholesaler of LED technology, Pixelight recognizes the VX400 PRO as a cornerstone for reliable video architecture. This controller excels in maintaining signal integrity across various pixel pitches, ensuring that fine-pitch displays (under 1.5mm) or standard outdoor SMD screens receive perfectly synchronized data. The integration of 4K@60Hz input processing means the device handles high-bandwidth content without frame drops, which is critical for maintaining a high refresh rate—essential for flicker-free performance under camera lenses.

Advanced Layering and Visual Fidelity

The VX400 PRO supports up to three independent layers, allowing for PIP/POP configurations that are vital for corporate presentations and broadcasting. By utilizing Novastar’s advanced processing algorithms, it optimizes the contrast ratio and grayscale transitions of your LED panels. This is particularly effective when used with GOB (Glue on Board) technology, where surface protection can sometimes impact light refraction; the VX400 PRO’s precise color calibration tools compensate for these variables, ensuring wide viewing angles remain vivid and accurate. Its low-latency mode minimizes the delay between the source and the screen, a non-negotiable requirement for live IMAG (Image Magnification) applications.

And the source, upstream?

The VX400 Pro receives a picture; it does not build one. As soon as content goes beyond a single loop, a playback application builds the programs and layers before handing them to this controller's 2.6 million loading pixels — at NovaStar, Kompass FX3 Pro, whose Basic edition is enough for a fixed installation.

Versatile Application Scenarios

The Novastar VX400 PRO is engineered for versatility across multiple sectors:

• Corporate Events & Boardrooms: Perfect for driving high-resolution indoor LED walls where crystal-clear text and seamless video transitions are required for presentations.
• Retail & Showrooms: Its compact 1U design is ideal for space-constrained installations in luxury retail environments, providing consistent brightness and color accuracy to enhance brand aesthetics.
• Live Stages & Houses of Worship: The low-latency processing makes it a favorite for live performances where synchronization between audio and video is paramount.
• Control Rooms: Reliable 24/7 operation and multi-windowing capabilities (PIP) allow operators to monitor several data feeds simultaneously on a single large-format LED display.
• Mobile Rental: For production companies, its "all-in-one" nature reduces the amount of rack gear needed, speeding up setup times for tours and temporary exhibitions.

Technical Optimization and Maintenance

To maximize the lifespan and performance of your LED system, our technical team recommends the following best practices for the VX400 PRO:

• Power Management: Ensure the unit is connected to a stable power supply. While the 1U chassis is efficient, always maintain adequate ventilation in your rack to prevent thermal throttling, which can affect the stability of the 2.6M pixel processing.
• Redundancy: For mission-critical events, utilize the Ethernet port redundancy feature. Pairing the primary outputs with a backup loop ensures the screen remains active even if a signal cable fails.
• Controller Settings: Use NovaLCT for initial configuration. Pay close attention to the "Cabinet Files" (.rcfgx) to match the refresh rate and scan mode of your specific LED modules.
• Viewing Distance: Ensure your input resolution matches the physical pixel count of the screen to avoid unnecessary scaling artifacts, preserving the sharpness of the content at the intended viewing distance.
