The Colorlight HC5 is a 5 Gb/s LED receiving card for fine-pitch screens in fixed installations and rental systems. Its high-density connector interface supports cabinet integration, while the wired data link is designed to carry more display data per network cable than a conventional Gigabit Ethernet system.
5 Gb/s display data transmission
The HC5 supports high-frame-rate and deep-color applications through its 5 Gb/s network signal transmission. In this product, “5G” refers to the wired data rate, not cellular connectivity. The actual cabinet load and cascade layout depend on the operating settings and compatible control-system hardware.
Calibration, monitoring and backup
HC5 supports HDR, full gamma adjustment, Infi-bit color extension and grayscale refinement. Low-grayscale, multi-layer and per-pixel brightness and chroma calibration assist screen adjustment. Seam correction, highlighting and OSD, image rotation and a pre-stored picture support cabinet setup and maintenance.
Up to 16 intelligent modules are supported. With compatible hardware, monitoring covers cabinet temperature, humidity, voltage and power. Configuration-parameter, calibration-coefficient and firmware redundancy protect setup data; loop redundancy, dual receiving-card hot backup and PSU redundancy support a configured backup system.

Frequently Asked Questions
Does “5G” on the HC5 mean a mobile network connection?
No. HC5 uses a 5 Gb/s network signal transmission rate for LED display control. The term describes the wired display data link, not a cellular modem.
What type of LED display is HC5 designed for?
HC5 is designed for fine-pitch LED screens in fixed installations and rental applications, using a high-density connector interface for cabinet integration.
Does HC5 support 12-bit video input?
The HC5 feature list includes 8-bit, 10-bit and 12-bit video source input, together with HDR and grayscale adjustment. Confirm the operating mode and compatible control-system hardware for the project.
What backup functions does HC5 provide?
HC5 supports loop redundancy, dual receiving-card hot backup and PSU redundancy, as well as redundancy for configuration parameters, calibration coefficients and firmware. Backup hardware and connections must be configured for the intended system.
What should I verify before using HC5 in an existing cabinet?
Confirm the controller’s data-link compatibility, connector pinout, module wiring and scan configuration, firmware and required load. Keep the cabinet configuration and calibration files available before replacement.
