That extension will activate external screens for computer login when your laptop is in clamshell mode. If DisplayLink icon is in the top menu bar and there's an exclamation point in the icon, you can click and it'll tell you it doesn't have screen record permission. I have exact same laptop and OS as you. The repeatable problem that DisplayLink has not addressed in my posts is whenever my laptop (which is clamshell mode) goes to sleep or I tell it to sleep, it will wake up and the installed "login screen extension status" will wake up the external displays. Here's the problem I'm having: as soon as I log in AFTER waking the computer from sleep, the screens go black and THE SCREEN RECORD PERMISSION that was working perfectly before sleep IS FORGOTTEN. Only 2 things correct the situation:

When connected to my screens, DisplayLink works great. My problem is when I remove my laptop, it then breaks. It appears to never realize and nothing is displayed on my laptop screen. The only way I can fix this is by hard rebooting (holding down the power button for 10s)

Go to system preferences > battery > and make sure "automatic graphics switching" is UNCHECKED in the power adapter and battery categories. If "removing my laptop" includes disconnecting from power, and your laptop is set to automatic graphics switching, it WILL switch graphics chips on-the-fly when you unplug power, and I don't think DisplayLink likes that. IIRC, my laptop would go black and only a force restart would get screen running again. |

I eventually had to use the gSwitch Application to stop Macos switching between discrete and integrated graphics and this seems to have resolved my problem
