This worked.
Stupid question, but now the display link user agent is now allowed to record our screen? Is this a privacy issue? |

Hi raym,
The new permission is required to be able to use an interface of the O/S that allows the driver to get pixels that are supposed to be displayed on screens connected to DisplayLink devices. Similarly, on Catalina, you probably noticed you are now being asked to grant permissions for various apps trying to access files in various locations on your disk that are potentially sensitive. (DisplayLink driver does not need any of that in order to work) Both examples are part of the improved security mechanisms Catalina brings - giving more control to users. Kind regards, Michal |

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.)

Tried it all but it still does not 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... |

Not solved!
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. |
