After struggling to find the solution, I installed 5.1.1 and it is now working again with the permissions checked to record screen.

https://www.displaylink.com/downloads/file?id=1334 is where 5.1.1 can be found.

this solution also worked for me. Uninstalled DisplayLink then installed 5.1.1. Nice to have my monitors back.

I got both my monitors working when I boot up but as soon as I undock my macbook and then plug it back in neither external monitor will reconnect, even if I log out and back in it doesn't work. Has to be a full reboot. Any ideas? I have the boxes ticked in both Accessibility and Screen Recording.

I know the subject says Solved, but it's not.

Running a 2018 MBP 15", Catalina 10.15, connecting via USB C. Got an ASUS ZenScreen, installed drivers 5.2 from DisplayLink. Install went fine, I approved the kext, and allowed the screen recording DisplayLinkUserAgent. Rebooted. Doesn't work. The display gives the error: "DisplayPort NO SIGNAL". When connected, the mouse cursor using the touchpad "sticks" every second and then catches up. Tried uninstalling, rebooting, re-installing - 3 times. Same exact thing. So it's definitely still broken. Anyone know when a fix will be coming or any other workaround?

(The only workaround I've found is to use a USB-C to USB-A adapter on the MBP t o convert the USB-C to A - that works... it's obviously not DisplayPort over USB-C anymore, but it does work. But using an adapter is a bad solution when it should just be fixed in software to make USB-C work.)

I have ticked it in privacy tab, did it in accessibility tab, but still does not work, the screen is still black, any other options have worked for others?

For me this is also NOT solved. I checked the appropriate boxes in the security settings but the third screen stays black. It is shown in System Preferences -> Monitors, but thats all, nothing is visible on the screen.
I have tried installing the older driver again, uninstalling and installing 5.2.1, nothing seems to helps.

MacBook Air (Beginning of 2015, 2.2GHz i7)

Now, again, after the desaster with MacOS 10.13, I am left with a missing screen in my working environment...

I've reinstalled the driver + Checked screen recording box + Reboot several times without succes. The displays show up in preferences, but they remain black. First install cursor was visible, now nothing.

Please fix this.

MacBook Pro (13-inch, 2017) with Dell U2717D external monitor.

After the upgrade, I simply missed the checkbox in System Preferences / Security & Privacy / Screen Recording. Made the mistake of installing the beta 2 driver, which did not work. Downgrading back to 5.1.1 and making sure the box was checked and bingo, I have my external monitor back.

Thanks man! With 5.1.1 it is working again. I just tried 5.2.0...

This is more of an FYI for others rather than a cry for help I can live without it until DisplayLink provide an update

Update:
When I say broken I mean I can see the mouse pointer but both external monitors are plank only my laptop screen is visible. Both network and mouse and keyboard all work without issue.

Update2:

I think I have fixed my problem under System Preferences / Security & Privacy / Screen Recording put a tick in the DisplayLinkUserAgent.app

This seem to solve my problem

My problem is that I can't find the DisplayLinkUserAgent.app anywhere. It's not under any heading in privacy at all.
