The MX20 is an all-in-one LED display controller in the brand-new control system COEX series of Xi'an NovaStar. This controller integrates video processing and video control into one box and offers 2x HDMI 1.3, 1x 3G-SDI input connectors, 6x Ethernet output ports, and 2x 10G optical ports. It can also work with the brand-new software VMP (Vision Management Platform) to provide a better operation and control experience.

− 2x HDMI 1.3 (with loop through)
− 1x 3G-SDI (with loop through)

6x Gigabit Ethernet ports, load capacity up to 3.9 million pixels
2x 10G optical ports
2x 10G optical ports
1x SPDIF digital audio port

− 1x Genlock signal input (with loop through)
− 2x Ethernet control ports
− 1x Auxiliary port

3 independent layers
Support up to 3 layers and layer priority adjustment in Z order.

Image scaling
Support 4 image scaling modes: custom, pixel to pixel, snap to canvas and fill screen.

14Ch Color Correction
Support precise adjustment to hue, saturation and brightness of black, white and the 12 derived standard colors of the red, green and blue primary colors.

Full-Grayscale Calibration
Work with NovaStar’s high-precision calibration system and the C3200 scientific grade camera to generate unique calibration coefficients for each grayscale, ensuring uniformity of each grayscale and dramatically improving the image quality.

  • This function can be achieved when the MX20 works with the A10s Pro receiving card. A C3200 camera is required to perform full-grayscale calibration.


Support low latency and the controller load capacity is not reduced. The latency at the controller is 0 frame (less than 1 ms) in Send- Only Controller working mode and 1 frame in All- In-One Controller working mode.

  • The Low Latency and Genlock functions are mutually exclusive. To enable low latency, please make sure all Ethernet ports load the cabinets vertically and share the same Y coordinate.

No rectangle restriction
No rectangle restriction for irregular screens. This means when calculating resolutions, blank pixels do not count towards the total capacity. The used load capacity of Ethernet ports is the sum of the resolutions of all cabinets.

Frame Rate Adaptive
The controller can be adaptive to various video input frame rates, including decimal frame rates. Custom frame rates are also supported and the step size of fine tuning frame rate is as small as 0.01 Hz.

  • This function can be achieved when the MX20 works with the A10s Pro receiving card. Currently supported driver ICs include ICND2055, ICND2065, ICND2069, MBI5253A, MBI5253B, MBI5754B, MBI5264, MBI5264B, MBI5264C, CFD555A. In addition, the .ncp file generated by the Cabinet Tool from NovaStar must be used.

Two working modes
Support the All-In-One Controller and Send-Only Controller working modes.

  • In the Send-Only Controller mode, the latency can be reduced by one frame.
  • In the All-In-One Controller mode, the layer and scaling functions are available.

Display system monitoring
Support monitoring of the device status and screen status. Any fault and alarm information can be reported actively.
