Thanks for posting. Good to know everything was working before the relocating; that helps narrow the focus. Let’s try the following:
Disconnect your docking station (power and USB) from your system and keep it disconnected until the last step. In this instance, let’s also disconnect the video cables from the dock as well.
Uninstall any and all software with ‘DisplayLink’ in the title that is present from within the Control Panel -> Programs and Features. Don’t worry if these entries are not present or if the process does not work, just move onto the next step
Thanks for giving that a try. We’ll want to take a look at some system logs to see what the best next steps will be. Can you please collect a set of logs using our tool at the page below: https://plugable.com/support/plugdebug/
Please collect the logs with both displays attached to the dock, even with the HDMI not functioning.
It will save a .ZIP file to your Desktop which can then be emailed to email@example.com (please put ticket 211134 in the subject if possible).
