About the NovaStar KU20
The KU20 is part of NovaStar's premium COEX Series (Creativity, Openness, Extensibility, Infinite possibilities), specifically designed for high-end display applications such as virtual production, studios, broadcasting, E-sports, and large-scale rental activities. This controller offers 1x HDMI 1.3 input, 6x Ethernet outputs and 1x 10G optical output. With a maximum loading capacity of 3.9 million pixels, the KU20 provides reliable performance for professional LED display applications. It features frame rate adaptive capabilities (23.98-480 Hz), pixel-level brightness and chroma calibration, full-grayscale calibration, and low latency operation. It supports two working modes (All-In-One Controller and Send-Only Controller) and works with VMP (Vision Management Platform) software to provide advanced operation and control experience.
About the NovaStar MX40 Pro
The NovaStar MX40 Pro is the flagship 4K LED display controller and video processor of the premium COEX Series (Creativity, Openness, Extensibility, Infinite possibilities), representing the pinnacle of LED display control technology for the world's most demanding applications: virtual production stages, xR/VP environments, LED cinema screens, broadcast studios, major E-sports tournaments, and mission-critical large-scale installations. This powerhouse controller introduces revolutionary Image Booster 2.0 technology, delivering unprecedented 22bit+ grayscale precision with 64-fold magnification and 0.002 nits minimum brightness control—enabling cinematic-quality blacks and shadow detail previously impossible in LED. Coupled with Dynamic Booster's intelligent frame-by-frame brightness optimization, the MX40 Pro achieves △E<2 color accuracy while reducing power consumption by 20-40%, and includes advanced SDR-to-HDR emulation for enhanced contrast without overexposure. Input versatility is unmatched: 3x HDMI 2.0 (up to 8192×1080@60Hz, 12-bit color), 1x DisplayPort 1.2 (4K@75Hz), and 1x 12G-SDI (4K@60Hz, 10-bit 4:2:2)—all with loop-through capability and full HDCP 2.2 compliance—making it the perfect hub for high-end production workflows. With a massive 20x Gigabit Ethernet outputs plus 4x 10G SFP+ fiber ports (switchable 20-port or 40-port optical mode), the MX40 Pro commands up to 9 million pixels (max 8192×8192) across 4 independent 4K layers with Z-order priority control. The processor supports adaptive frame rates from 23.98-480 Hz (including decimal rates) with frame multiplication, ensuring perfect synchronization for camera systems via Genlock with loop-through. Sub-1ms latency at the sending card maintains real-time responsiveness without sacrificing loading capacity. Advanced color science includes 3D LUT support (17³/33³/65³ for professional grading), Color Replacement, 14-channel Color Correction, Color Curves, and pixel-level brightness/color calibration. Native HDR10 (SMPTE ST 2084) and HLG (BT.2100) support delivers true high dynamic range, while 3D display capability (with specialized cards) opens new creative possibilities. The MX40 Pro's "no rectangle restriction" calculates capacity based on actual physical pixels—not wasteful rectangular bounds—and supports irregular screen shapes for creative installations. With 128 customizable presets for instant scene switching, SPDIF digital audio output, built-in cascading control, and a 3.5-inch TFT touchscreen, operation is both powerful and intuitive. Fully integrated with NovaStar's VMP (Vision Management Platform) software and featuring xR virtual shooting with shutter fit technology, the MX40 Pro delivers a complete ecosystem for professionals who demand absolute excellence, precision, and reliability in high-profile LED display applications where failure is not an option.
