Thanks for reaching out to us, I’d be more than happy to assist you with your Plugable USB3-HDMI-DVI display adapter.
In the past, we’ve seen these type of issues being caused by a problem with drivers on the system. In order to figure out what exactly is going on, we’ll want to get a bit of additional information. To do so, we’ll want you to run our log gathering tool Plugdebug. Simply go to this site, follow the prompts there, and send us the resulting .zip file.
