NovaStar VX400 Pro 4K All-in-One LED Video Controller

NovaStar VX400 Pro 4K All-in-One LED Video Controller

The NovaStar VX400 Pro LED Video Controller combines LED display processing and video control in one rackmount unit for rental, stage, and fine-pitch LED systems. Four Gigabit Ethernet outputs handle up to 2.6 million pixels, while the processor supports video inputs up to 4096x2160@60Hz and LED canvases up to 10,240 pixels wide or 8,192 pixels high.

Designed for professional LED wall control, the VX400 Pro accepts HDMI 2.0, HDMI 1.3, 3G-SDI, optical, and USB media sources. Six 2Kx1K layer resources can be allocated as 4Kx2K, 4Kx1K, or 2Kx1K layers, giving production teams flexible composition options. Full-screen, pixel-to-pixel, and custom scaling support unusual canvas formats, while Video Controller, Fiber Converter, and ByPass modes adapt the processor to different signal-chain requirements.

The VX400 Pro also supports low-latency processing, EDID management, output color adjustment, pixel-level brightness and chroma calibration, and multiple backup methods. Operators can control the unit from its front panel, NovaLCT, Unico, or the VICP app. CE, FCC, IC, PSE, RCM, EAC, UL, CB, KC, and RoHS certifications support professional integration requirements.
