usb-c 4k no display output from display ports to 2k monitors, connected to Macbook pro 15

usb-c 4k no display output from display ports to monitors, I have 2 x Dell 2k monitors connected via displayports, not getting any output to either monitor. Even if I connect just 1 monitor via display port, still no output to monitor. This is a new Macbook Pro touch bar.

Hello Mark,

Thank you for contacting Plugable support! Sorry to hear about this issue. I’d be more than happy to assist you.

I suspect if the DP ports are not working, that Gatekeeper is blocking the DisplayLink driver. We’ve seen this before. To resolve it you need to do the following:

  1. Uninstall DisplayLink drivers:…
  2. Reboot, then reinstall them again (… ), and after then immediately check Gatekeeper (… ).

That process of uninstall, reboot, reinstall, Gatekeeper settings should resolve this problem.

Please don’t hesitate to let us know of other questions.

Thanks again for contacting Plugable support and best wishes!
