Mac Mini (M1, 2020) - Monterey v12.4
 

Had an older intel mac mini fail. When switching to new mac mini screens connect but stay black. They are visible inside the displaylink application and inside the display settings of the mac. However, they are black in extended display mode. When I change them to mirrored, they work fine.

Is this an error confined to the M1 mac Mini, should I return this one and get the intel version to get this working now?

Thanks

Hello,

If the monitors were ever rotated or are rotated now please follow the steps below and reset them. Then connect everything the way it was - if you are using rotation please rotate the screens via the DisplayLink Manager rotation settings.

The steps to reset the screen persistence:

1. Unplug the dock and restart your machine to make it operational again.
2. Download fixing script from our website: Reset macOS display persistence.
3. Unpack the archive, so that you have ResetDisplayPrefs.command in your Downloads folder.
4. Run Terminal and execute these commands to run the script:
   
   HTML Code:

   ---

   cd ~/Downloads
chmod +x ResetDisplayPrefs.command
sudo ./ResetDisplayPrefs.command

   ---

5. The script has to be run with administrator privileges, this is required to forcefully delete defective system settings. Type in your password and press enter.
6. The script will display list of*display-related settings*files that will be deleted and will ask for confirmation before proceeding.
7. After confirmation the script will delete those files, forcing MacOS to recreate them from scratch.
8. After the script finishes it will ask you to reboot your machine. You can plug in your dock after reboot.
9. Unplug the dock and restart your machine to make it operational again.
