Sudden Incompatibility Between KTC Monitor and DisplayLink Docks on MacBook Air

[supershnee]

Overview:

I have been using my DisplayLink devices without any issues for several months. My setup includes:

DisplayLink Docks (used one at a time):
Pluggable USBC-6950M
Satechi Triple 4K Docking Station

Monitors:
Dell monitor
KTC monitor - KTC 24 Inch QHD 2560x1440 IPS Computer Monitor

Laptop:
2024 MacBook Air running Sequoia 15.1
Issue Description:

On November 2nd, after my MacBook Air woke from sleep mode, the KCTC monitor stopped working with both of my DisplayLink docks. The Dell monitor continues to function perfectly with the DisplayLink docks, and the KCTC monitor works when connected through the Apple-branded dock. This suggests that the issue is specifically between the KCTC monitor and the DisplayLink docks.

Troubleshooting Steps Taken:

Tested both DisplayLink docks individually with the KCTC monitor.
Used multiple monitor cables to rule out cable issues.
Performed several system reboots and reconnected all devices.
Verified that the DisplayLink docks' Product IDs are correctly recognized by the system.
Noted that, on rare occasions after multiple attempts, the KCTC monitor is detected by the DisplayLink docks, but this is inconsistent.
Request for Assistance:

What could be causing the sudden incompatibility between my DisplayLink docks and the KCTC monitor, and how can I resolve this issue?

Additional Information:

The issue began without any known changes to the system or hardware.
Other peripherals connected to the DisplayLink docks function without issues.
No error messages or alerts appear when the KCTC monitor fails to connect.

Note from Admin, please do not double-post about this issue in other threads.

If you have not done so already, I would suggest using the DisplayLink End-User Cleaner tool --> https://support.displaylink.com/know...tool-for-macos to completely remove the current version of DisplayLink Manager and then perform a fresh install of the latest version of DisplayLink Manager available version 1.11 --> https://www.synaptics.com/products/d...ownloads/macos

If that does not help resolve the issue, then I would suggest reporting the issue to DisplayLink directly by following the process outlined here --> https://support.displaylink.com/know...to-displaylink
