Display Link Stopped working on 3 monitors with M1

Thanks for the update. It's going to be difficult to assess what's going wrong without logs. Could you please follow this article to capture debug data: https://support.displaylink.com/know...to-displaylink

I have an M4 MBP 14' with Tahoe 26.3.

It connect to
1. One monitor directly though USB Type-C.
2. One Targus Dock which connects to two monitors.

It works perfect before Tahoe.

And now, the two monitors can be both detected by DisplayLink, but only one can be detected by the OS. If I disable the one which detected by the OS, on DisplayLink, the other one screen on immediately.

I was told that it may cause by FileVault for some privacy reason, which makes no sense to me.

Hello,

What is your Targus product? Are you on the latest available DisplayLink Manager for macOS?

Here is my Dock im using
https://www.lenovo.com/us/en/p/acces...4aAi7KEALw_wcB

but as mentioned even with a DP to Usb-C cable it is not working seems like a display port is not functioning on M1 Mac

Thanks for the info.
The Lenovo dock you linked is a Thunderbolt dock, not DisplayLink and unfortunately, we won't be able to help in this case.

Thank you for replying.

Targus USB-C DV4K Docking Station 100W Power
Amazon Link: https://www.amazon.com/Targus-Univer.../dp/B07BPQKP8V

I did install the latest one (15.1.0 build 51).
It doesn't work on both DisplayLink 13 and 15.1.0.

I am also having an issue with my two monitors. (only one screen is working)

I have two identical DELL monitors that worked fine before, up until 2 hours ago. The only thing that I did and that seems to have messed up everything is that I updated my OS to Tahoe version 26.3.1 (25D2128)

For context, my monitors are connected to a Dell Universal Dock UD22 using HDMI and DisplayPort. I have been using this setting for the past 6 months with no issues with version 14.

I tried to update to version 15, but ended up having the same issue. I still have a single monitor working.
