Colorlight LED: Processors, Controllers, Software & Downloads
Colorlight LED products cover the full signal path of an LED display: video processors, control systems, cloud players, and the software that ties them together. The product line is wide, and the specifications are dense. So this guide breaks it down for you.
We also cover the software tools and point you to free downloads. By the end, you should know exactly which product fits your project.
1. About Colorlight Cloud Tech Ltd
Colorlight Cloud Tech Ltd is a video display and control company based in Shenzhen, China. It builds LED display control systems, video processors, and cloud-connected playback products. Its products run in stage rental, broadcast, virtual production, and digital signage projects around the world.
The product line falls into three categories:
- Video processors – handle signal switching and image quality
- LED control systems – carry the signal from the processor to every cabinet
- Cloud players – store and publish content without a connected computer
Because Colorlight designs all three categories itself, the products work together as one system. And that is exactly how most projects deploy them.
Colorlight’s Calibration Technology Patent
LED displays drift out of color balance over time. Lamps age, viewing angles change, and ambient light shifts through the day.
Colorlight holds a patent for rapidly updating calibration coefficients to counter this problem. Instead of a slow manual recalibration, intelligent algorithms refresh brightness and chromaticity coefficients across the screen. So the display keeps accurate colors throughout its service life, and maintenance cost stays low.
2. Colorlight LED Processor
A video processor sits between your signal sources and the LED screen. It switches inputs, scales images, manages color, and drives the display at the right frame rate. In other words, the processor you pick shapes both picture quality and system flexibility.
The two models below cover the most common high-end scenarios. Both are strong products, but they solve different problems.
2.1 Colorlight Z6 PRO-G2
The Z6 PRO-G2 is a new-generation professional LED display controller. It combines video splicing, processing, and sending in one chassis, and Colorlight positions it for cinematic work: high-end stage rental, XR virtual shooting, and movie production.
✔ Input and output
- Input: four 4K card slots, mixable between HDMI 2.0, DP 1.2, and 12G-SDI
- Each card supports up to 4096×2160@60Hz at 8/10-bit, 23.98–240Hz
- Output: 4×10G fiber ports (2 main + 2 backup)
- Loading: 8.80 million pixels per output group, 13.10 million total; max width or height 8,192 pixels
✔ Cinema color tools
Color is where this Colorlight LED controller earns its place on film sets. It ships with three professional color tools:
- 3D-LUT – cinema-grade color adjustment, the same technology used in film production
- Color Magic – adjusts one specific color based on the HSV model without touching others
- Color Curve – fine-tunes RGB and brightness at individual grayscale levels, so highlights stay clean and low-grayscale details stay visible
✔ More key specs
- HDR10 and HLG display with wide color gamut
- Up to 4-window processing, low latency, frame multiplexing for multi-camera shooting
- Frame rate multiplication up to 6×
- Control via USB cascading, RS232, and LAN (TCP/IP)
2.2 Colorlight VX20
The VX20 is an all-in-one LED video controller for rentals, large events, and fine-pitch screens. It loads up to 13.1 million pixels, with a maximum width of 16,384 pixels. Everything ships in one box, so setup on site is quick.
✔ Connectivity and work modes
- Inputs: 2×12G-SDI, 2×DP 1.2, 2×HDMI 2.0, 4×HDMI 1.4, most with loop outputs
- Outputs: 20 Gigabit Ethernet ports + 4×10G fiber ports
- Three work modes: Video Processor, Fiber Optic Transceiver, and Bypass (0 frame delay)
Whatever signal a client throws at you on show day, this processor probably takes it. And the three work modes let one box adapt as the job changes.
✔ Operation and image quality
A 3.5-inch touchscreen handles setup without extra equipment. A cross-platform web app also works on Windows, macOS, and Linux with no install. For image quality, the VX20 supports HDR10 and HLG, frame rates up to 240Hz, PVW/PGM preview, and a full redundancy set.
In short, the Z6 PRO-G2 targets film sets and broadcast, while the VX20 targets rental crews and live events.
3. Colorlight LED Control System
A complete Colorlight LED control system has two halves. A sender pushes the processed signal out from the front, and receiving cards inside each cabinet drive the LED modules. The sender decides how big your system can grow, while the receiving cards decide how good each cabinet looks.
3.1 Colorlight S20 LED Sender
The S20 is a 2U sender box designed for ultra-long, ultra-high, and ultra-large screens.
✔ Key specs
- Loading capacity: up to 8.85 million pixels, max width or height 8,192 pixels
- Input: 1×DP 1.2 and 1×HDMI 2.0 at up to 4096×2160@60Hz, with seamless switching
- Output: 20 Gigabit Ethernet ports, up to 650 thousand pixels per port
- Redundancy: both Ethernet port redundancy and controller redundancy
One rule deserves attention: the per-port capacity reduces when the loading height exceeds 1,280 pixels. So plan your cabinet layout around it.
The S20 also supports USB cascading, RS232 protocol control, separate audio I/O, and optional 3D display. Better still, it is compatible with all Colorlight receiving cards and multifunction cards, so you can pair it freely with the cards below.
3.2 Colorlight K10 Receiving Card
The K10 is a high-end receiving card developed for fine-pitch LED screens. Its high-density connectors save space inside concise cabinets and improve dust and shock resistance.
✔ Key specs
- Control area: up to 512×512 pixels per card
- Data groups: 32 parallel or 64 serial RGB, expandable to 128 serial
- 8/10/12-bit video input, HDR10 and HLG
- High frame rate output at 120/144/240Hz
- Pixel-by-pixel calibration up to 14-bit precision
That calibration precision matters on fine-pitch walls. It keeps colors uniform across the entire screen, even at close viewing distance. The card is also rated for 7×24 uninterrupted work, with loop redundancy, dual-card hot backup, PSU redundancy, and firmware redundancy.
3.3 Colorlight E320 Pro Receiving Card
The E320 Pro is a cost-effective receiving card released in July 2024. Its goal is simple: cut costs, reduce failure points, and lower failure rates. Even so, it does not feel like a budget card on paper.
✔ Key specs
- Control area: up to 512×512 pixels, the same as the K10
- Data groups: 40 parallel or 120 serial
- 8/10-bit video input, HDR10, frame rates up to 240Hz
- Infi-bit grayscale compensation, up to 4,194,304 levels
- Pixel-level brightness and chroma calibration, integrated HUB75 connectors
The Infi-bit number deserves a second look. It pushes grayscale far beyond the standard level, so low-brightness scenes keep their detail instead of turning muddy. Add built-in temperature and voltage monitoring, a test button, and firmware upgrade without power interruption, and you get K10-class control area on a tighter budget.
The rule of thumb is simple: pick the K10 for fine-pitch image quality, and pick the E320 Pro when budget leads.
4. Colorlight Cloud Players
Cloud players solve a different problem. A synchronous control system needs a signal source running all the time, but a cloud player does not. It stores content on the device, follows a schedule, and publishes programs on its own. Colorlight’s A-series plugs into the ColorlightCloud platform, so one operator can manage screens across different cities from a browser.
Colorlight A200 Cloud Player
The A200 is a new-generation cloud networking player that supports both synchronous display and asynchronous playback.
✔ Key specs
- Asynchronous loading capacity: up to 2.3 million pixels
- HDMI output up to 1920×1200@60Hz
- Hardware decoding: 4K H.265/H.264 and 4K VP9
- 32 GB internal storage (about 25 GB available)
- Networking: WiFi (hotspot or client), LAN, optional 4G
Through the ColorlightCloud platform, the A200 supports player monitoring, program scheduling, centralized publishing, and multi-level privilege management. Programs can also run plug-and-play from a USB flash drive.
Content creation happens in PlayerMaster, Colorlight’s editing tool for A-series players. You arrange multi-window layouts freely and mix video, pictures, text, clocks, streaming media, webpages, and weather feeds. Typical applications include outdoor advertising screens, public information displays, and chain-store screens that need unified management across regions.
5. Colorlight LED Software
Hardware sets the ceiling, but software decides how much of it you actually use. Colorlight keeps its software lineup focused, and all of it is free:
- Colorlight iSet – configures and diagnoses the control system
- Colorlight LEDSetting – debugs screen parameters and manages calibration
- Colorlight LEDVISION – handles playback and tuning alongside the two tools above
5.1 iSet
iSet is Colorlight’s professional software for configuring and controlling LED displays. Connect it to your processors over USB or a network cable, and it detects all connected devices automatically.
Three jobs make up most of the daily work:
- Routing topology – sets the connection map so signal flow matches the physical cabinet layout
- Parameter tuning – adjusts brightness and color; the Capacity Calculator works out each output port’s loading capacity
- Diagnostics – health monitoring tracks temperature, humidity, cable error rate, power supply, and receiver status in real time
iSet runs on 64-bit Windows 7 or later, and it works with Colorlight LED controllers such as the Z6 PRO-G2 and VX20.
5.2 LEDSetting
LEDSetting is the parameter debugging tool for Colorlight’s synchronous control system, designed to work together with LEDVISION. While iSet focuses on device configuration, LEDSetting goes deeper into screen setup.
Its core jobs include:
- Debugging screen parameters across Colorlight’s full product portfolio
- Working with a wide range of driver ICs, screen models, and display configurations
- Manual calibration of LED displays, plus importing calibration data from third-party professional tools
The software runs on Windows 10 and Windows 11, and 4 GB of RAM is enough for smooth operation. If you need precise control over how your screen looks, this is the tool to open.
6. Colorlight Resources Download

What software do I need for a Colorlight LED display?
For synchronous systems, use iSet to configure processors and run diagnostics, with LEDSetting for screen parameter debugging and calibration. LEDVISION handles playback and tuning. A-series cloud players are managed through PlayerMaster and the ColorlightCloud platform. All software is free on LedInCloud.
Does iSet work with all Colorlight LED controllers?
iSet works with Colorlight LED controllers such as the Z6 PRO-G2 and VX20. The software detects connected processors and receivers automatically once you connect a PC through USB or a network cable. It runs on 64-bit Windows 7 or later.
8. Conclusion
Colorlight LED products cover the full path from signal to screen, and each category plays a clear role. Video processors like the Z6 PRO-G2 and VX20 handle image quality and switching. The S20 sender works with K10 or E320 Pro receiving cards to drive every cabinet reliably. The A200 cloud player publishes content on its own through the ColorlightCloud platform. And the software trio of iSet, LEDSetting, and LEDVISION keeps the whole system configured and running.
So which products should your project use? Follow the signal path, and the answer becomes clear.
- First, size the processor to your screen’s pixel count and application
- Then pick a sender with enough output ports for your cabinet layout
- Next, choose receiving cards that match your pixel pitch and budget
