Dell D6000 - no monitors detected macOS Tahoe 26.3.1 & DisplayLink Manager 15.1

Hi automised_matt,

I had a quick check of your logs. What is wrong - there are no signs of monitor presence connected to the dock. Does any of the monitors appear when you unplug and plug monitor DP cable or power cycle the monitor?

BTW thanks for the pointers, however "Couldn't read values in CFPrefsPlistSource..." is not an indication of something going wrong here

One thing to note: with FileVault enabled you won't be able to use DisplayLink displays on the login screen anyway.

Regards,
Szymon
