Monitors doesn't wake on macOS Tahoe (26)

Hi,
I have a similar issue in my enterprise environment. Issue started occurring after Tahoe 26.0.0. update & Display Link 14.0 install.

UGREEN Revodok Pro 209 USB C Docking Station
MacBook Pro, Apple M3
ASUS ProArt PA278QV
ASUS ProArt PA278QV (Two monitor environment)
Both connected to UGREEN dock with Display Ports

The MacBook Pro, Apple M3 is currently on Tahoe26.0.1 but issue persists. Almost every time that system sleeps one monitor will not come back on, sometimes both monitors will not come back on. General troubleshooting (unplugging, replugging cables, restarting computer, powercycling dock, sometimes fix it but sometimes don't for no clear reason)

I've also tried swapping out the MacBook Pro, Apple M3 running Tahoe 26.0.1 for a MacBook Pro, Apple M2. The issue does not occur as frequently on the Apple M2. Only a fraction of the time when it sleeps will the monitors not come back on.

What's the recommended way to upload the logs? I receive a 413 Request Entity Too Large (nginx) error when trying to upload logs generated from the SupportTool.
