Thanks for posting and I am sorry to hear of this issue! Based off of your description we’ll want to make sure that the software used by our adapter is in a good state. To do so, please follow these steps:
Disconnect the adapter from the system. Please keep it disconnected until the last step.
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
