Does My TBT4-UDZ Need Updated Firmware?

The TBT4-UDZ generally does not require any firmware to be updated. If you are not currently experiencing video issues, this update is not needed. However, in some cases a new firmware version may be helpful if you are experiencing video related issues, and after standard troubleshooting (such as operating system, device driver, and UEFI / firmware updates to the host system) has not helped.

Why You Might Need to Update the Firmware

A firmware update may help resolve the following video-related issues:

  • Display instability such as intermittent flickering, flashing, or a black screen
  • Display not detected after waking from sleep, or is detected but no image is displayed
  • DisplayPort display not detected, but using HDMI for the same display works as expected

Note: Updating the dock firmware will not help with other non-video related issues, if experiencing other issues please contact us at support@plugable.com and we'll be happy to assist.

How to Update the Firmware

To update the firmware, you will need access to a Windows 10 or Windows 11 system with Thunderbolt 3, Thunderbolt 4, Thunderbolt 5, or USB4. Standard USB-C systems may also support the update process if they support USB-C DisplayPort Alternate Mode. The firmware update cannot be performed on a Mac or Linux system.
