Colorlight software and driver downloads
The Colorlight software download you need depends on the hardware generation and the job you need to perform. LEDVision is the first choice for configuring many Colorlight sending and receiving systems. LEDShowT9 supports compatible asynchronous playback workflows, while Calibration Pro is intended for supported brightness and color calibration work. Drivers are only needed when Windows does not recognize the connected sender or USB device.
Which Colorlight software should you download?
- LEDVision V4.20: start here when you need the newer LEDVision package listed in this archive.
- LEDVision V3.66: keep this legacy version available for older projects that were created or commissioned with it.
- LEDShowT9 V11.32: use it only with a Colorlight product and workflow that specifically requires LEDShowT9.
- Calibration Pro 2.31: choose this tool for supported LED display calibration tasks.
- Sender-card or iT7/iQ7 driver: install the matching driver when the controller is not detected through its intended connection.
Compatibility note: do not assume that the highest version number is automatically the best choice for an older screen. Confirm the controller model, receiving card model, current configuration, operating system, and project file before upgrading.
Colorlight setup tutorials
These PDF guides cover common setup procedures for selected Colorlight cards and sending boxes. A model-specific manual should take priority over a general workflow because connector layout, supported capacity, firmware, and configuration options can differ.

Basic Colorlight LED controller setup workflow
- Identify every model. Record the sending controller, receiving card, hub board, multifunction card, and display cabinet details.
- Back up the working configuration. Read and save the existing sender and receiving-card parameters before changing them.
- Install the matching software and driver. Connect the controller only through the interface described in its manual.
- Set the input and screen parameters. Confirm input resolution, cabinet dimensions, scan configuration, port mapping, and total load.
- Test one section first. Verify data direction, color order, brightness, grayscale, and module mapping before sending parameters to the full display.
- Save the verified configuration. Keep a dated backup that can be restored if the screen is serviced later.
Colorlight LED controller card specifications
Use the specification PDFs to compare product type, interfaces, supported functions, and intended system role. The list includes integrated controllers, sending boxes, asynchronous players, receiving cards, multifunction cards, and a 3D sender. Product purchase links are retained where they were available in the original article.
How to choose a Colorlight controller or receiving card
Start with the system architecture rather than the model name alone. A synchronous display normally receives live video from a sending controller, while an asynchronous player stores and schedules content. Receiving cards sit inside the cabinets and must match the module wiring, scan mode, load requirement, and hub design.
- Check pixel capacity and port loading: calculate the real screen width, height, cabinet layout, and pixels assigned to each output.
- Match the workflow: decide whether the display needs real-time video, scheduled playback, or an all-in-one controller with processing.
- Verify cabinet compatibility: receiving-card size, connectors, hub interface, scan type, and firmware support must suit the cabinet.
- Plan required interfaces: confirm video inputs, Ethernet outputs, control connections, sensor support, audio, and any redundancy requirement.
- Use the model PDF: capacity and feature limits can vary between products with similar names, so verify them in the exact specification.
Download and installation notes
- PDF files contain manuals, setup instructions, or specifications and can be opened with a standard PDF reader.
- ZIP and RAR files are compressed archives. Extract them with a trusted archive utility before installation.
- Security software may warn about older installers or compressed files. Scan every download and use it only when the model and source are expected.
- Do not overwrite a stable production configuration without a restorable backup and an approved maintenance window.
- If a link opens but the file does not download, allow the browser download for this site and try the link again.
Frequently asked questions
What is Colorlight LEDVision?
LEDVision is configuration and management software used with supported Colorlight LED display control systems. Typical tasks include screen mapping, sending-device settings, receiving-card parameters, brightness control, and saving configuration files.
Should I use LEDVision V4.20 or V3.66?
Use the version confirmed for your controller, operating system, and existing project. V4.20 is the newer version in this archive, while V3.66 can be useful for legacy installations. Back up the current configuration before changing versions.
Are these the latest Colorlight downloads?
This page includes archived resources for the models and installations listed above. Software and firmware can change over time, so check the official Colorlight website or your equipment supplier when you need the newest supported release.
Can one Colorlight manual be used for every controller card?
No. General concepts may be similar, but port capacity, connectors, firmware, supported functions, and setup screens vary by model. Use the manual and specification for the exact product whenever possible.
What is the difference between a sending controller, receiving card, and multifunction card?
A sending controller processes or distributes the video signal to the LED display network. Receiving cards inside the cabinets translate that data for the LED modules. A multifunction card adds auxiliary control such as supported sensors, power sequencing, or other system functions, depending on the model.
What should I do before loading a receiving-card configuration?
Confirm the module type, scan mode, data direction, color order, cabinet resolution, and wiring. Save the current working parameters first, then test the new configuration on a limited section before applying it to the entire screen.
Need help matching a download to your hardware?
Send the exact controller and receiving-card model, a photo of the label, and a description of the task through the contact page. This information makes it easier to identify the appropriate software, manual, or specification without guessing.
