Optional Firmware Update for USBC-PDMON

Last Update: December 4th, 2025
Article ID: 3602491

We periodically release firmware updates for the Plugable USBC-PDMON to improve compatibility and resolve issues. This consolidated article outlines which units may benefit from updated firmware, and which specific fixes would be implemented in each update.

Firmware installation is optional and should only be applied if you are experiencing an issue that the updates address.

Who Should Install This Firmware Update?

Look at the first four digits of the monitor’s serial number.
Example serial number format: 4812-XXXXX

Serial Number Prefix Factory Firmware Version Notes
Up to 4314 v209 Original firmware version
4314 and above v210 Enhances video contrast when using the sRGB display mode
4622 and above v212 Enables DDC/CI support for software-based brightness/contrast control
4812 and above v213 Improved compatibility with certain Android smartphones that may negotiate incorrect display resolutions

If your unit’s serial number is 4812 or higher, it is already up-to-date and does not require an update.
 

Should You Install the Update?

You may want to install the latest firmware if:

Your serial number is earlier than 4314 and you want improved sRGB contrast

Your serial number is earlier than 4622 and you want DDC/CI support for software brightness/contrast

Your serial number is earlier than 4812 and you are experiencing issues when connecting certain Android smartphones

If your monitor is working normally and you do not need these enhancements, updating is optional.
