Colorlight X20 LED controller with 13-million-pixel loading
The Colorlight X20 combines video processing and LED sending for large display systems. Its six video inputs include DP 1.2, HDMI 2.0, two HDMI 1.4 and two DVI connections. The controller supports up to 13 million LED pixels, with a choice of twenty Gigabit Ethernet outputs or two 10G optical outputs.
Specifications below follow X20 Specification Version 2.0. The Ethernet and optical output modes cannot operate at the same time. Confirm the intended transmission method, receiving cards and pixel allocation before choosing the hardware and accessories.
X20 video inputs and LED output limits
| DP 1.2 input | 1; maximum 4096 × 2160 at 60 Hz |
|---|---|
| HDMI 2.0 input | 1; maximum 4096 × 2160 at 60 Hz |
| HDMI 1.4 / DVI inputs | 2 of each; maximum 1920 × 1200 at 60 Hz |
| Input depth | 8-bit formats listed in Version 2.0 |
| Total LED loading | 13,000,000 pixels |
| Gigabit output mode | 20 × 1G Ethernet ports; up to 650,000 pixels per port |
| Optical output mode | 2 × 10G fiber ports; alternative to Ethernet output |
| Separate dimension limits | Maximum width 16,384 pixels; maximum height 8192 pixels, within total loading |
Maximum width and maximum height are separate limits. Keep the total screen within 13 million pixels and check the load assigned to each output.
Optical transmission and output planning
FIBER 1 corresponds to Ethernet outputs 1–10, while FIBER 2 corresponds to outputs 11–20. The specification describes separately purchased 10G single-mode optical modules with dual-LC connections, 1310 nm wavelength and a 2 km transmission distance. Confirm the modules, converter and cabling for the required distance before ordering.
For Ethernet transmission, Version 2.0 recommends a maximum Cat 5e cable run of 100 m. It also lists redundant backup support; configure the actual redundancy topology and verify the resulting available loading for the project.
Windows, scenes and control
The X20 supports up to six overlaid windows, free window positioning and scaling, cropping and seamless switching. The minimum window or crop size is 64 × 64 pixels. Check the intended input combination and layout on the supplied firmware before committing to a multi-source design.
Sixteen preset scenes can be saved and recalled. Color-gamut management requires receiving cards that support the corresponding feature. Brightness, color temperature and low-brightness grayscale controls support display adjustment. Optional 3D requires the appropriate separately purchased accessories, including the emitter and active glasses.
Control methods include the front-panel LCD and knob, USB computer connection, USB cascade output, LAN TCP/IP, RS232 and an Android mobile app. The RS232 connector is RJ11 6P6C; follow the specified RJ11-to-DB9 wiring when integrating central control.

Allow for rack mounting, rear connectors, cable bends and ventilation. Confirm the supplied device’s installation measurements against the drawings before making a fixed enclosure.
Frequently asked questions
Can X20 Ethernet and fiber outputs work simultaneously?
No. Version 2.0 requires choosing either the twenty Gigabit Ethernet outputs or the two 10G optical outputs.
Are X20 optical modules and 3D accessories included?
The specification identifies the optical modules and corresponding 3D accessories as separate purchases. Confirm the required configuration and included accessories with the order.
Do all six X20 video inputs support 4K at 60Hz?
No. DP 1.2 and HDMI 2.0 support up to 4096×2160 at 60Hz. The two HDMI 1.4 and two DVI inputs support up to 1920×1200 at 60Hz.
How does the X20 compare with the X8E?
The X20 specification lists 13 million pixels and twenty Gigabit or two optical outputs. The Colorlight X8E specification lists 5.24 million pixels and eight Gigabit outputs. Choose according to screen resolution and the transmission plan.
Can the X20 play videos from a USB flash drive?
The X20 V2.0 specification assigns USB to PC control and controller cascading. It does not document USB-drive media playback.
