NovaStar MX20 COEX LED display controller
The MX20 is an all-in-one controller for LED screens using HDMI or 3G-SDI video sources. Its six Gigabit Ethernet outputs carry screen data, while two separate Ethernet control ports connect the controller to NovaStar VMP. Two 10G optical outputs provide a fiber data path, with the second optical port duplicating the first.
Three layers and two operating modes
In All-In-One Controller mode, arrange up to three independent layers and adjust their Z-order. Scaling modes include custom, pixel-to-pixel, snap-to-canvas and fill screen. Use Send-Only Controller mode when the application needs the documented reduction of one frame in controller latency.
The low-latency feature provides less than 1 ms at the controller in Send-Only mode or one frame in All-In-One mode. It cannot run simultaneously with Genlock. It also requires all Ethernet ports to load cabinets vertically with the same Y coordinate. Zero to two additional frames can be configured when delay is needed.

Color calibration and cabinet configuration
Fourteen-channel color correction adjusts black, white and twelve derived colors by hue, saturation and brightness. This is a 14-channel function, correcting the earlier listing’s description of twelve channels. Full-grayscale calibration uses A10s Pro receiving cards with NovaStar’s calibration system and a C3200 camera.
Frame Rate Adaptive requires A10s Pro receiving cards, one of the driver ICs listed in the specification and a Cabinet Tool .ncp file. For irregular screen layouts, blank areas do not count as cabinet load; use the sum of the loaded cabinets and the detailed port-load table when planning the screen. VMP also provides device and display monitoring.
Frequently Asked Questions
How many pixels can the NovaStar MX20 control?
The maximum device load is 3.9 million pixels. Actual usable capacity depends on the frame rate, bit depth, receiving card and cabinet mapping, so use the specification’s port-load tables for the selected configuration.
Does the MX20 accept a 4K HDMI source?
Its listed HDMI input maximum is 1920 × 1200 at 60 Hz. The custom wide format of 3840 × 600 at 50 Hz is not a 3840 × 2160 4K input. Match the source output to a supported format.
Does the MX20 support picture-in-picture layouts?
Its All-In-One Controller mode supports up to three independent layers, adjustable in Z-order, with custom, pixel-to-pixel, snap-to-canvas and fill-screen scaling.
Can I use Genlock with low latency enabled?
No. These features are mutually exclusive in the linked V1.0.0 specification. Low latency also requires vertical cabinet loading and the same Y coordinate across all Ethernet ports.
Is the MX20 USB port used to play video files?
The front USB 2.0 port is documented only for exporting diagnostic results to a USB drive, supporting NTFS and FAT32. The MX20 receives live video through its HDMI or SDI inputs.
