Just came back from vacation and turned on my Macbook 15" 2018-era laptop running macOS 12.2, only to find that the monitor plugged into my D6000 dock via DisplayPort no longer works? Another monitor, plugged in via HDMI to the same dock, is fine.
I updated the DisplayLink Manager app from 1.5 to 1.6 to 1.6.1 and no change. I get the same error about "No DisplayLink-enabled display detected" in the DisplayLink Manager app. Updating macOS Monterey from 12.2 to 12.2.1 did not fix anything.
Basically, the DisplayPort connector seems like it just no longer works
The monitor that no longer works is using DisplayPort v1.4, btw (I tried 1.2, since it allows changing this, but to no effect).
