The TBT4-UDZ generally does not require for the firmware to be updated, 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.
Examples of possible video related issues that updating to new firmware may help with:
- Display instability such as intermittent flickering/flashing/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.
If you are experiencing any of the above issues, 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 system, or systems running Linux. If you do not have access to a compatible Windows system to perform the firmware update please contact us for assistance.
Please follow these PDF instructions to download and perform the firmware update:
