S4: Compact sender for small-to-medium displays, a popular choice for indoor conference room LED walls.
S2: Entry-level sender for simple single-cabinet or small signage applications.

Receiving Cards (Receivers)

Colorlight’s receiving card ecosystem is organized into performance tiers:

5G Series: Next-generation receivers leveraging Colorlight’s 5G transmission protocol. Supports 240Hz refresh rates and HDR metadata passthrough — critical for esports arenas and broadcast studios where camera flicker is unacceptable.
i Series (i10, i9+, i8, i5+): High-performance receivers for professional rental and fixed installations. The i10 supports up to 512×512 pixels per card.
k Series (k10, k9+, k8, k5+): Cost-optimized receivers for standard fixed installations and outdoor billboards.
E Series (E320, E120, E80): Compact receivers designed for rental cabinets where space and weight are at a premium.
5A-75E / 5A-75B: Standard HUB75 interface receivers compatible with most generic LED modules on the market.

Control Software: LEDVISION & LEDUpgrade

The core software for configuring Colorlight control systems is LEDVISION — a Windows-based application that handles receiving card configuration (loading .RCFGX files), screen connection mapping, brightness calibration, and firmware management. Its companion tool, LEDUpgrade, is used for batch firmware updates across multiple receiving cards simultaneously — a major time-saver for large installations.

For integrators and technicians, LEDVISION’s intelligent settings wizard can auto-detect module parameters (scan mode, data polarity, driver IC type) by reading the module’s data signals — significantly reducing commissioning time compared to manual configuration.

Colorlight Cloud: Asynchronous Control & Remote Management

Colorlight’s asynchronous ecosystem is built around the Colorlight Cloud platform — a browser-based content management system (CMS) that lets operators remotely manage LED displays across multiple cities from a single dashboard.

The hardware backbone of this system is the C Series Cloud Player line (CPLAYER), which connects to the cloud via 4G, Wi-Fi, or Ethernet. Once deployed, you can:

Push video, image, and text content to individual screens or groups
Schedule playlists by time, date, and location
Monitor screen health — temperature, voltage, signal status — in real time
Receive automated alerts for fan failures, overheating, or signal loss
Adjust brightness schedules based on ambient light conditions

For single-display scenarios that don’t require cloud connectivity, Colorlight also supports USB drive playback and direct PC connection via the PlayerMaster and Assistant desktop applications.

Media Servers & GrandShow: Powering the Ultra-High-Resolution Era

As LED display resolutions push beyond 8K into 16K territory, traditional PCs can no longer decode and play back video smoothly. Colorlight’s media server line — the CS16K, CS20-8K PRO, and CS4K PRO — are purpose-built hardware appliances designed to handle massive video files with hardware-accelerated decoding.

The secret weapon is GrandShow, Colorlight’s self-developed media server software that ships pre-installed on every CS-series device. GrandShow’s signature capabilities include:

16K native playback: Smooth, frame-accurate playback of 16K video files on a single device — no multi-PC sync required
3D projection mapping: Real-time warping and blending for projection onto irregular surfaces, buildings, and sculptural LED installations
GrandShow Sync: Proprietary frame-level synchronization technology that keeps dozens of media servers locked to the same frame — essential for immersive domes, 360° LED stages, and large-scale architectural mapping
NDI and ST 2110 support: Native integration with broadcast IP-video workflows for live production environments

Key Technologies That Define Colorlight’s Competitive Edge

5G+8K Transmission Technology (2026)

Colorlight’s most significant 2026 announcement is its 5G+8K LED display transmission solution. This technology increases the loading capacity per Ethernet cable by 500% compared to conventional Gigabit transmission, while reducing the total cabling required by 80%. For integrators, this means: fewer sending cards, simpler wiring, lower cabinet weight, and support for 240Hz refresh rates — a game-changer for fine-pitch LED walls in broadcast and esports environments.

Infi-bit Grayscale Processing

Colorlight’s proprietary Infi-bit algorithm delivers superior grayscale performance at low brightness levels — a common pain point for indoor LED displays. Where conventional controllers lose visible bit depth when dimmed below 30% brightness, Infi-bit maintains 16-bit grayscale fidelity even at 5% brightness, preserving shadow detail and preventing color banding in dark scenes. This is particularly valuable for broadcast studios, home cinema, and museum applications.

Scientific-Grade Calibration System

Colorlight has invested over 10 years of R&D into point-by-point calibration technology — the process of individually measuring and correcting the brightness and color of every single LED pixel on a display. Their calibration solution is particularly strong in:

COB (Chip-on-Board) calibration: COB panels present unique calibration challenges due to their encapsulation layer. Colorlight’s scientific-grade solution compensates for the optical properties of the COB resin to achieve uniform output.
Multi-batch uniformity: When a large LED wall spans cabinets manufactured in different production batches, Colorlight’s calibration can harmonize color and brightness across all units — eliminating the “patchwork” effect.
HDR calibration: Supports calibration profiles for HDR10 and HLG workflows, ensuring accuracy across standard and high-dynamic-range content.

ST 2110 & IPMX: Broadcast-Grade IP Video

For broadcast and live production, Colorlight offers native SMPTE ST 2110 and IPMX (Internet Protocol Media Experience) support across select X Series processors and media servers. This enables direct integration with broadcast IP-video infrastructures — no external converters required — making Colorlight one of the few LED control brands with genuine broadcast-native capabilities.

How to Choose the Right Colorlight Controller: A Decision Framework

Determine your resolution: Calculate total pixels (Width × Height). This sets the minimum sending card requirement. For displays under 2.6 million pixels, an S4 or S6F is sufficient. Above that, consider the S20/S20F.
Decide sync vs. async: Real-time video → synchronous (S series senders + processor). Scheduled content → asynchronous (C Series Cloud Player + Colorlight Cloud).
Count your inputs: Multiple HDMI/SDI/DP sources? You need a video processor (X Series or Z Series), not just a sending card. The X7 is the sweet spot for most 3–4 input setups.
Check for broadcast requirements: Genlock, ST 2110, or 240Hz refresh needed? Step up to the X16E/X20 or Z8t with 5G receivers.
Consider creative complexity: 3D, projection mapping, irregular cabinets? Z Series + GrandShow is the recommended path.
Match receivers to your cabinet type: Rental (lightweight) → E Series or 5A-75E/B. Fixed (reliable) → i Series or k Series. Future-proof (5G/8K ready) → 5G Series.
