The MCTRL300 is an LED display controller developed by NovaStar. It supports 1x DVI input, 1x audio input, and 2x Ethernet outputs. A single MCTRL300 supports input resolutions up to 1920×1200@60Hz. The MCTRL300 communicates with PC via type-B USB port. Multiple MCTRL300 units can be cascaded via UART

As a highly cost-effective controller, the MCTRL300 can be mainly used in the rental and fixed installation applications, such as live events, security monitoring centers, and various sports centers.


  •  2 types of input connectors
    − 1x SL-DVI
    − 1x AUDIO
  •  2x Gigabit Ethernet outputs
  •  1x light sensor connector
  • 1x type-B USB control port
  • 2x UART control ports
    They are used for device cascading. Up to 20 devices can be cascaded.
  • Pixel level brightness and chroma calibration Working with NovaLCT and NovaCLB, the controller supports brightness and chroma
    calibration on each LED, which can effectively remove color discrepancies and greatly improve
    LED display brightness and chroma consistency, allowing for better image quality.
