DiplayLink broken after Catalina 10.15 Update

Rick H. · 11-09-2019, 11:22 PM

I'm having the same issue as Seth. After Catalina upgrade, my second and third displays are black. They are active however and I can activate an application blindly.

I have two Plugable docking stations, a three monitor w/2 4k connects and an older version w/ 2 HDMI connects.

I've tried downloading both display driver beta 2 & 3 to no avail. The drivers are loading and my Screen Recording Displaylink User Agent is checked.

Plugable gave up and referred me to DisplayLink.

Help!

darthjr,

We have identified that part of Dell D6000 docks produced between mid 2018-mid 2019 contains USB Hub firmware issue that was uncovered by macOS Catalina 10.15.1 release.

There is a for that.

Please update your dock hub using "Dell Firmware Update Utility":

I did that based on feedback from another support thread. Still didn't work.

I am facing the same issue. I upgraded to 10.15.1 from Mojave and then later tried installing beta3 version. I have connected 2 external monitors via D6000 docking station. When i connect my mac to the docking station the screen keeps flickering.

I tried with 5.1.1 version of the driver without any luck.

Can someone please recommend me what can be done to fix this issue?

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.
