Desktop arrangement forgets when Mac sleeps
 

I have two additional monitors and the multiple display setup works a treat with the adapter.

I regularly use multiple desktops to separate work tasks and also hide a bunch of stuff when I'm on zoom.

When my mac sleeps and wakes up, the separated desktops and respective apps within all get dumped onto my second monitor and I have to rearrange them back each time.

Does anyone know any ways in which I can prevent this?

Same issue here, with a Macbook Air M1. I tried everything, with the precious help of the OWC hub seller (macway.fr) Impossible to make it work: once asleep and waked-up, DisplayLink Manager doesn't recognise my two HDMI screens. Had to systematically unplug and replug my OWC DisplayLink USB-C Dual HDMI 2.0 4K adapter.

Once monitors are detected again, I had to setup their arrangement again.

I'm pretty sure it is not an hardware problem, but a software one. Same issue with version 1.7 or 1.8 (beta at this stage).

Had this issue for a long time, and found a way to work around it.

1. Install DisplayPlacer

```sh
brew tap jakehilborn/jakehilborn && brew install displayplacer
```

2. Configure the displays to be on the definitive arrangement you want it to be

3. Run `displayplacer list`. This will print a long output but what matters to us is at the end:

```
...
mode 47: res:3360x1890 hz:60 color_depth:4 scaling: on
mode 48: res:3840x2160 hz:60 color_depth:4 scaling: on
mode 49: res:4096x2160 hz:60 color_depth:4 scaling: on

Execute the command below to set your screens to the current arrangement:

displayplacer "id:65CF52D2-4D65-9866-C792-BAE1233F7DFE res:1680x1050 color_depth:4 scaling:on origin:(0,0) degree:0" "id:ED61CFA3-165E-4A21-2F94-B100084444A1 res:1080x1920 hz:60 color_depth:8 scaling:off origin:(3600,-840) degree:90" "id:0000410C-0000-08CC-0000-0CEE00000000 res:1920x1200 hz:60 color_depth:4 scaling:off origin:(1680,-1200) degree:0" "id:00004C2D-0000-0D20-4357-413400000000 res:1920x1080 hz:60 color_depth:4 scaling:off origin:(1680,0) degree:0"
```

Now we can use the command provided there to restore the display arragement.

4. Save the last emitted line to a script and run that script whenever the screens are misconfigured.

I've linked this script to a shortcut so whenever screens are out of place I press the shortcut and they automagically restore themselves.

Hello,

Please reset screen preferences and check if the issue persists:

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:
   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 and check if the issue persists.
