Third monitor only works when plugged into laptop HDMI

Hello… I had three DP monitors working, and now the third will not work unless it’s plugged into the HDMI port on the laptop. I’ve tried HDMI on the plugable, however it does not work. I’ve updated all video drivers, uninstalled and reinstalled the DisplyLink drivers while using the cleanup utility with the same results. If I plug a different laptop in everything works fine, so I’m fairly sure it’s not a cable/device issue. It seems the laptop HDMI port is not being “redirected” to the plugable? Thoughts?
Thank you

Hello,

Thank you for contacting Plugable! I’m sorry the UD-ULTC4K isn’t working as expected, and I’ll be happy to assist.

The fact that the dock works fine on one computer and not on the other points to a possible issue with the laptop itself (provided that the laptop was the only thing changed in the setup between tests).

With this in mind, can you please send an email to our direct support email address (support@plugable.com) with “For ticket # 456618” in the subject line? In the email, please include the following information:

  1. The Amazon Order ID number for your docking station purchase
  2. While the docking station is connected to your PC (even if not working as expected), the output of our diagnostic utility PlugDebug: https://plugable.com/pages/plugdebug

This information will help us to determine the next steps.

** Please do not post the above information here in our public forum (it contains personally identifiable information) **

Apologies for the frustration, and thank you for giving us the chance to help!
