The NovaStar KU20 is a very popular and comprehensive LED display controller, and the latest model in NovaStar's renowned COEX series, engineered for versatility and supporting both All-In-One and Send-Only Controller modes to adapt to diverse LED display requirements. With a maximum loading capacity of 3.9 million pixels, the KU20 delivers sharp visuals and reliable performance for both creative and traditional LED wall configurations, making it one of the most capable LED video controllers in its class.
Advanced features such as image scaling (custom or pixel-to-pixel), full grayscale calibration, pixel-level brightness and chroma correction, and its ultra-low latency (zero frame and less than 1ms) make it ideal for demanding environments like live events, rental LED setups, broadcast studios, and fine-pitch LED displays. With High Frame Rate support up to 120Hz and 22Bit+ Image Boost Mode, the KU20 ensures stunning, professional-grade visual output in any setting.
The KU20 is fully compatible with NovaStar's Armor (AXs) series receiving cards, including the A10s Pro, A8s Pro, A8s, A8s-N, A7s Plus, and A5s Plus, breaking the limitations of rectangular LED screens by mapping any desired topologies and irregular-shaped displays with no waste of loading capacity. Without doubt, the best match for this controller is the A10s Pro, which unlocks 10-bit output, full grayscale calibration, and frame rate adaptive functionality.
Its HDMI 1.3 input — with an HDMI loop port for cascaded devices — supports resolutions up to 1920×1200@60Hz, with flexible scaling for ultra-wide or tall screens (max width: 3840, max height: 2560). Six Gigabit Ethernet ports and a 10G optical output ensure fast, stable data transmission even for large-scale installations.
When combined with the CVT10 fiber converter, the optical port enables noise-free long-distance data transmission of up to 10km, allowing you to control and drive a full 1080P LED screen with ease. Thanks to its dual Gigabit Ethernet control ports and built-in network switching function, you can cascade up to 20 units to run any multi-screen or complex display configuration required for large rental or fixed LED installations.
Powered by NovaStar's VMP (Vision Management Platform) software, users can easily customize display parameters such as brightness, color temperature, and gamma for any selection of cabinets — even across groups of cascaded units — in a simple and efficient manner. Each configuration can be saved as a unique preset, with up to 128 presets stored and instantly applied with a single click, making it perfect for fast-paced live event production and rental LED display workflows.
All these features, combined with its compact half-1U rack-mountable design (fits two units in a standard 19-inch rack), dimensions of 10.01" × 1.99" × 11.42" (254.3 × 50.6 × 290mm), and broad international certifications (CCC, CE, FCC, IC, UL, CB, PSE, RCM, EAC, KC), have made the NovaStar KU20 a smart, highly sought-after, and cost-effective choice for professional LED display projects worldwide.
