Hi Daryl,

Thank you for posting! I am sorry things are not working fully as expected while using your TBT4-UDZ docking station, and I would be happy to help.

A quick important note, previously you said:

“…i also downloaded the latest diplaylink driver and installed it but it doesn’t work …”

For your reference, the TBT4-UDZ does NOT have DisplayLink USB video technology inside of it. As a result, it is not necessary to install a DisplayLink driver in order to use the product.

With that said, based on your description of the behavior, our next step is to get some additional information.

Can you please send an email to our direct support email address → support@plugable.com with ‘For ticket #- 432466’ in the subject line that contains the following information?:

  1. The Amazon Order ID number for your TBT4-UDZ purchase

For your reference, that information is typically available from here → https://amazon.com/orders

  1. While the TBT4-UDZ is connected to your computer and all of the external displays are connected to the TBT4-UDZ (even if not working as expected), the output of our diagnostic utility PlugDebug → https://plugable.com/pages/plugdebug

This information will help us to determine the next steps.

*** Please do not post the information we requested above here in our public forum (it contains personally identifiable information) ***

Apologies for the frustration, and thank you for giving us the chance to help!
