How can you tell if the DL-3900 you have is a 3900C or 3900Z?

How can you tell what the final letter is of the model number of your docking station? I have a DL-3900 but I don’t know if it’s a 3900C or 3900Z or some other final letter. Thanks for your help?


Thank you for contacting Plugable! I would be happy to provide additional information regarding our docking stations.

To clarify, the specific variant of your dock should be listed on the bottom of your docking station, with the types listed as follows:

UD-3900 (Vertical, HDMI/DVI ports)
UD-3900C (Vertical, two HDMI ports, same exterior as the UD-3900)
UD-3900Z (Vertical, two HDMI ports, more modern case)
UD-3900H (Horizontal, HDMI/DVI ports)

Hopefully this information was helpful, but please feel free to reach out if you have any follow-up questions or concerns.

Thank you!
