1. What Is the Novastar KU20 LED Video Processor?
The Novastar KU20 LED Screen Controller is an advanced LED display controller that redefines visual excellence. Designed as part of NovaStar’s COEX series, the KU20 offers a robust combination of hardware and software solutions for seamless LED screen management. With 6 Ethernet ports, 1 HDMI input, and 1 optical output, it supports versatile connectivity options for a wide range of applications.
One of its standout features is its compatibility with the Vision Management Platform (VMP), NovaStar’s latest software solution. VMP enhances the user experience by providing intuitive controls, smart device management, and real-time monitoring. Whether you’re setting up a rental display, configuring irregular screens, or calibrating pixel-level brightness, the KU20 ensures precision and efficiency in every step.
2. Core Features That Make the KU20 LED Display Controller Stand Out
2.1 Advanced Image Scaling
The Novastar KU20 supports two image scaling modes: custom scaling for flexible adjustments and pixel-to-pixel scaling for precise image reproduction. This feature allows users to adapt content seamlessly to their display requirements, ensuring optimal clarity and detail.

2.2 Full Grayscale Calibration
Paired with NovaStar’s high-precision calibration system (CC3) and scientific-grade cameras like the CC60 or C3200, the KU20 generates unique calibration coefficients for each grayscale level. This ensures uniformity across all grayscales, dramatically improving image quality and consistency.
2.3 Low Latency Performance
For applications requiring minimal delay, the KU20 excels with 0-frame latency (less than 1 ms) in Send-Only Controller mode. Additionally, users can add zero to two frames of latency to synchronize with high-latency equipment, making it ideal for live events and dynamic displays.

2.4 Frame Rate Adaptability
The KU20 adapts seamlessly to various video input frame rates, ranging from 23.98 Hz to 480 Hz. It also supports custom frame rates with precision down to 0.01 Hz increments, ensuring smooth playback and consistent brightness across different frame rates.
2.5 No Rectangle Restriction
Unlike traditional controllers, the KU20 eliminates rectangle restrictions for irregular screens. Blank pixels do not count toward the total capacity, allowing for flexible resolution planning and efficient load distribution.
2.6 Dual Working Modes
The KU20 supports two working modes:
- All-In-One Controller Mode: Enables layer creation and scaling functions.
- Send-Only Controller Mode: Focuses on streamlined data transmission without additional layers.
This versatility makes the KU20 suitable for both simple and complex display setups.
