Hello,

Thank you for contacting us!

Please run a short script in the terminal as a command. It will reset display settings and restore display persistence. It should allow to save your screen layout settings.

Perform these actions only with 1 laptop display, do not attach any external monitors.

1. Download the file: https://www.displaylink.com/downloads/file?d=145
2. Run the file (it will give you an information that it is not authorized due to security)
3. If you will see the message about security -> Go to Security & Privacy, General tab, choose: Allow App Store and identified developers.
4. Next to it you should have a pop up message about our display persistence script.
5. It will open terminal after double click and ask for the password, put the password.
6. Reboot your computer

Thank you,
Katarzyna
