Second monitor keeps going black and sound goes out with it

This is my second unit as I had the previous one replaced for the same issue.

I’m currently only using 2 monitors connected via Display Port. The second monitor continually goes black about 2-3 times per minute. I have swapped monitors and both of them do it. I have also looked at other posts, cleared the displaylink drivers, and re-installed them. This is happening to me on both a ThinkPad T14 and Dell Lattitude. I’m also using the cables provided with the unit.

When the second monitor goes out, so does the audio when selecting pluggable audio.

I was expecting more from a device that costs around $300.


Hi Tony,

Thank you for posting! I am sorry your docking station is not working as expected and I would be happy to help.

Thank you as well for the detail you provided and the testing you have performed that is much appreciated. Based on your description of the behavior, our next step is to get some additional information.

Please keep the dock connected to your system (even though not working) and send the output of our diagnostic utility PlugDebug → to us directly via with ‘For Ticket 394762’ in the subject line. This will allow us match things up and examine some log files from your system to help determine the next steps.

Please also include your Amazon Order ID number for the docking station purchase in your direct email. Please do not post the Order ID or the PlugDebug file in our public forum.

Thank you for giving us the chance to help!
