DiplayLink broken after Catalina 10.15 Update

[jromero]

Read through this thread. Here's what I did to get mine working:

macOS Catalina 10.15.1

I had installed the latest version 5.2.1, but when I plugged in the dock, my MBP screen kept flickering on and off. did all the suggested steps including

https://support.displaylink.com/know...-functionality

so I uninstalled this version and installed 5.1.1 (older downloads section), still din't work. so then I disconnected the dell dock and connected it to a Dell Laptop and upgraded the firmware using the dell dock firmware utility updated to the latest it found (0017)

Still running 5.1.1 and now the two external monitors I have are working.

Please try newer dell dock firmware utility that installs 0019 latest drivers:
https://www.dell.com/support/home/uk...sal-dock-d6000

And that one should work fine with Catalina 10.15.1 and 5.2.1 beta3 Displaylink driver.

Catalina 10.15.1, Displaylink 5.2.1 beta3 driver, and Dell D6000 dock firmware utility that installs 0019, was the magic combination. I'm fully functional.

Now, if we can get a macOS firmware updater for the D6000 dock... (Its Windows-only.)

Great Find!
