Blank Secondary monitor

I have the Plugable UGA 3000 and was having a problem early last Spring. You walked me through a number of steps and the problem resolved itself for a long time. I am now having problems again. When I boot up my system the secondary monitor screen flashes on, but then goes black. The system is recognizing both monitors. If I shut the secondary monitor off and then on, it again flashes on for a few seconds and then goes black. Thanks for your help. Jerry Nelson

Hi Jerry,

Thanks for posting! Sorry to hear that this behavior started again and I will be happy to help!

In looking up past tickets I found one other ticket from you where the cleaner steps seemed to help resolve the issue for you and based off of your description we’ll want to walk through them in order to make sure that the software is in a good state. To do so, please follow these steps:

  1. Disconnectthe adapter from your system. Please keep it disconnected until the last step
  2. Uninstall the DisplayLink Core software from the Control Panel -> Programs and Features. Don’t worry if this fails, just move onto the next step
  3. Download, extract and run the DisplayLink cleaner tool, found here -->… and ensure it displays “Cleaning Complete” when done (video walk-through ->
  4. Once the Cleaner has been run, reboot (even if not prompted to)
  5. Now download and install the 8.0 M1 DisplayLink software, found here -->…
  6. Reconnect the adapter to your system when prompted by the installer which will trigger the final portion of the installation

If these steps help, great! If not, we’ll want to examine some log files to see if they can tell us what is happening. To help us do so please download and run our diagnostic utility PlugDebug --> just after the behavior has occurred and you have restarted so we can try and capture the behavior. Please send us the file that is created on your Desktop by sending it to our direct email at with ‘Ticket Number 151819’ in the subject line so we can match everything up. We’ll examine the logs and determine next steps from there.

Thank you,
