UD-3900PDZ macbook 16 m1 pro - 2 monitors flashing

I have three monitors connected and the two that are not on the alt-connection but display link flash for about two seconds at the same time every hour or so very random. Sometime within a few minutes of doing it but mostly every hour or so. I’m running an new macbook 16 M1 pro on Monterey 12.0.1 andDisplayLink Manager 1.2.0 (Build 55.125)


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

Thanks for providing the details about your setup! We would recommend upgrading the DisplayLink Manager to the newest non-beta version which is 1.5 from Sep 8, 2021 (instead of the 1.2 you’re running now as that version is quite old, from Dec 10, 2020).

You can find the newest version 1.5 here: https://plugable.s3.amazonaws.com/bin/DisplayLink/DisplayLink+Manager+Graphics+Connectivity1.5-EXE.pkg

And you can find our full installation guide here: https://kb.plugable.com/questions/799275

If you still encounter issues after the upgrade, or have trouble upgrading to 1.5 from 1.2 please let me know.

Thanks again for contacting Plugable support and best wishes!
