Understand MaxColor Series Firmware Compatibility

Last updated: Nov 04, 2026

Choose Firmware for Your Task

Use this reference to check video compatibility, hardware support, and control-driver requirements before downloading or applying MaxColor Series firmware.

Your Task What to Check
Update an existing system Identify the installed firmware family. Changing between v3 and v4 requires planning for all devices that must exchange video.
Add or replace a device Match the destination system's firmware family and verify that the selected release supports the exact device model.
Check a control driver Check Legacy API support and model-specific features separately from video compatibility. A supported driver does not make different product series video-compatible.

For the current package, use Download MaxColor Series Firmware. For previous release notes and downloads, use MaxColor Series Firmware Release History.

Check Video Compatibility

Match the firmware family: MAX v4.x.x and MAX v3.x.x are not video-compatible. Do not update one device to another major version while the devices it must exchange video with remain on the previous family.

MaxColor Series devices do not exchange video with Omega Series, Ultra Series, or 2G Series devices. Updating firmware does not add that interoperability.

MAX v3.7.4 is compatible with the MAX v3.x.x family. Review each release's hardware and feature requirements when adding a device.

Check Hardware Support

Select firmware intended for the exact hardware model. A firmware-family match alone does not establish that an older package supports a newer device.

Historical MAX v3.7.4 Hardware

The MAX v3.7.4 release lists these supported models:

  • MC-RX1
  • MC-RX2
  • MC-TX1
  • MC-TX2

Use this list for that historical release. Review the release record before maintaining a v3 installation; do not use this list as a model-support table for every MaxColor firmware package.

Check Control Compatibility

MAX v4.x.x supports existing control system drivers that use Legacy API command syntax. Feature support still depends on the device and release.

MAX v4.5.0 includes _4in1_layout.sh and _4in1_primary_audio.sh translation scripts for basic legacy Ultra Series Tiler driver control on QX devices. These scripts translate control commands; they do not make MaxColor Series and Ultra Series video streams compatible.

Understand the Version Format

MaxColor firmware uses the format MAX vX.Y.Z. For example, MAX v4.5.1 is a release within the v4 family.

Component Meaning
MAX MaxColor Series firmware.
First number Major firmware family. The v3 and v4 families are not video-compatible.
Remaining numbers Identify the specific release within that family. Review its notes for changes and hardware requirements.

Select, Update, and Verify

Download the package for the intended release and use the file intended for the exact device model. Follow How to Update Firmware on a Device for the webUI or AMP procedure.

After updating, confirm the installed version using How to Identify the Firmware Version of a Device and test the installation's video, audio, switching, USB, and control features.
