NovaStar KU20 is an exceptional LED display controller from the COEX series. This controller redefines visual excellence, providing an array of features designed to elevate your LED display experience. With 6 Ethernet ports, 1 HDMI input, and 1 optical output, the KU20 integrates seamlessly into NovaStar's COEX ecosystem, ensuring precision and performance.


Key Features

  • Rich Connectivity: The KU20 offers versatile connectivity with 1x HDMI 1.3 input (with loop through) and 6x Ethernet ports, supporting a load capacity of up to 3.9 million pixels.

  • High Precision Calibration: Utilize NovaStar's high-precision calibration system and the C3200 scientific-grade camera for pixel-level brightness and chroma calibration. Achieve uniformity in brightness and chroma across each pixel for a consistently stunning display.

  • Advanced Image Scaling: Benefit from two image scaling modes - custom and pixel to pixel - providing flexibility in adapting content to your display.

  • No Rectangle Restriction: Enjoy freedom with no rectangle restrictions for irregular screens. Blank pixels are excluded from load capacity calculations, offering flexibility in resolution planning.

  • Frame Rate Adaptive: The KU20 adapts seamlessly to various video input frame rates, supporting decimal frame rates and allowing custom frame rates with precision down to 0.01 Hz.

  • Display System Monitoring: Stay in control with active monitoring of device and screen status. Receive instant notifications for any faults or alarms, ensuring a reliable performance.

  • Two Working Modes: Choose between the All-In-One Controller and Send-Only Controller modes. In the All-In-One Controller mode, unlock layer and scaling functions for enhanced control.

  • VMP Software Integration: Seamlessly connect to NovaStar's Vision Management Platform (VMP) software for easy and convenient operations, providing smart device management.

  • Cascading Control via Ethernet: The Gigabit Ethernet control ports support TCP/IP protocol and star topology, eliminating the need for additional switches or routers. Cascade multiple devices effortlessly on the same LAN.


Function Limitations:

  • Frame Rate Adaptive and Full Grayscale Calibration functions require compatibility with A10s Pro receiving cards and specific driver ICs.
  • To enable low latency, ensure uniform cabinet placement vertically and sharing the same Y coordinate across all Ethernet ports

Certifications: CCC, CE, FCC, IC, UL, CB, PSE, RCM, KC
