iMac 2019 - 3 monitors - Catalina 10.15.4

[GJS]

Hi There,

I have a 27" 2019 iMac with 3 displays. I have my iMac in the middle with a Samsung SyncMaster T220 on each side.

Everything works, but.....

When I power off and back on, the monitors re-arrange themselves so that the Samsung monitors are both on the left hand side of my iMac monitor.

Is there a way or place for me to have my preferred arrangement stick? So I don't have to reset this each time I power down and back up.

We live in a very Rural environment where the power goes out at least once a month. So I find powering everything off when I am done using it to be the safest way to preserve my equipment.

Best regards,

Glenn :confused:

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.

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


Thank you,
Katarzyna
