You can update the firmware using a PC or Laptop and our firmware update tool.
Before you begin: Use Google Chrome, Microsoft Edge, or Opera. Make sure your USB cable supports data transfer — power-only cables will not work.
Use a USB-C data cable to connect the Mercury Screen to your computer.

Put the screen into firmware update mode:
Visit the firmware update tool page and click Connect Device at the top.

Click Install next to the latest Screen firmware.

A progress bar will show the erase and install phases. The full process typically takes 45 seconds to 1 minute.


Don’t panic: The progress bar may sit on 99% or 100% for 30–40 seconds at the end while the new firmware is verified. This is normal.
Once complete, press the RESET button to restart the screen with the new firmware.
