How would I connect 1 monitor using an hdmi cable to the plugable docking station.
Thanks for posting your question here! A DVI to HDMI passive adapter is enclosed in the package with the Plugable UD-3000 in order to connect a monitor via HDMI to the DVI port on the dock.
Please note that as the default output of the graphics port on the Plugable UD-3000 is DVI and since DVI does not have any support for audio, audio will not pass to the monitor through this HDMI connection.
Hope the above information helps! If you need any additional information, please do feel free to shoot us an email at email@example.com. We are here to help!
