[Solved] New MacOS Catalina breaks DisplayLink

[SterlingBourne]

For me broken means the monitors don't recognize the MacBook Pro at all; they just go to sleep. I don't have a Screen Recorder option in Settings to enable.

So right now I'm just looking at 2 dead monitors next to my Laptop until a new driver is released that supports Catalina.

I would suggest you look under every option in the Privacy tab under "Security & Privacy" in System Preferences look for DisplayLinkUserAgent.app it appears in two places for me Screen Recording and Accessibility

Also if this was the first time you installed the driver you will need to click allow under the General Tab Its been a while since I read the install notes on the readme but I think that requirement is detailed there

Fixed it.

My issue is I wasn't running v5.1.1. Once I installed the latest version, and enabled Screen Recording, both of my external monitors worked.

This seem to solve my problem

Dude that saved me hours of investigation. Worked perfectly (after reboot)

Thanks!!!

I don't know if this is monitor specific, but with Mojave I had my two external monitors set to 60 Hertz and all was good but with the Catalina install, the refresh on the external monitor was lagging severely. Changing the refresh rate to 59.88 Hertz (NTSC) fixed this for me.

There are a lot of right answers in this thread but one that is seemingly missing is to update your docks firmware. This requires a windows computer (don't try with a VM).

Hello, I followed all the latest instructions but the DisplayLink option doesn't show up in the Privacy settings and I can't find a way to add it manually.

How did you do?

I ended up connecting my MacBook to power directly and then then Hub to another USB port - that worked for me ...
