Display Link Stopped working on 3 monitors with M1

appletechieguy · 02-13-2026, 01:15 AM

My Display Link stopped showing all three displays starting this week, it had been working great. I had my M1 Mac running MacOS 26.2 connected to a LG HD QHD and my LG Ultrawide. I can get my built in display and one of the two monitors to connect correctly but not all three. I can see all three monitors but only one or the other LG will allow me to move content to the display. I updated to MacOS 26.3 with no success.

Hi,
Do your monitors appear in the Displays tab of DisplayLink Manager app and are they enabled like in the picture?

Yes and can see both monitors and both are selected but only one is active and visible in my list of displays.

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?

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.

Hi all. I'm new to this forum only because I also suddenly had my third monitor stop working and had no clue why. Checked and removed/reconnected all connections between MAC laptop and 2 monitors, reinstalled updated DisplayLink and followed ALL the steps it indicated to make sure the icon is in menu bar, screen recording on, etc. After an hour of all that and trying to get answers via these forums, I did the old school thing... unplugged EVERYTHING from the wall outlet, power strips, you name it! Plugged it all back in and now third monitor is up and running. NO CLUE why it came to that, but thought I'd pass along the tip in case it helps others. Will have to see if once it all goes to sleep as I walk away tonight, if all monitors will work tomorrow.

I had this exact same problem with my setup and tried this low tech fix and was amaxed that it worked.

The order I followed:
1. unplugged both monitors
2. unplugged dispalylink hub
3. updated displaylink driver to latest
4. shutdown laptop
5. plugged in displaylink hub
6. plulgged in both monitors
7. turned on laptop

It works. Thanks for the suggestion.
