DisplayLink turn off on Sonoma 14
 

Periodically, the DisplayLinkManager automatically turns off and the two external monitors turn off. This could be every couple of minutes, or maybe as many hours. 2-3 weeks ago, there was no such problem.
DisplayLink version 1.10.0.
MacBookPro M1 2021.
Sonoma 14.1.2
Dock-station:Lenovo ThinkPad Hybrid USB-C with USB-A Dock 40AF0135EU
Two monitors connected to dockstation by HDMI amd Display Port. And doc station connected to mac by usb-c
When DisplayLink turned off, dock station continue work correct, all usb diveces work.
I try change version of DP drivers to 1.9 but same issue. I found similar problems on the forum, but there was no solution.

This issue may be caused by a conflict between the DisplayLink drivers and the Parallels video driver.
You can try resetting the DisplayLinkManager by following these steps:
Open Terminal: You can find Terminal in Applications > Utilities > Terminal.
Type the following command and press Enter: sudo killall DisplayLinkManager
Type your password when prompted and press Enter.
Restart your MacBookPro.

I never use or install Parallels. Or it installed on Mac by default?

Based on the information you have provided, one item of note is that you do not have the latest version of macOS installed as of today. You have 14.1.2, however the latest version is 14.2.1.

I would suggest updating to the latest version of macOS in order to see if that changes the behavior.

If updating macOS does not resolve the issue, then I would suggest reporting the issue to DisplayLink directly by following these steps --> https://support.displaylink.com/know...to-displaylink

So I am try again downgrade DisplayLinkManager to version 1.9.0. and this already one week work fine
