Multiple Monitors Change Positions After Sleep/Power Off/Disconnected

[scottw1204]

Hello,
First, thank you for creating BetterDisplay! It's an outstanding utility that has been a big help configuring my monitors. I bought the Pro Version and love it.

Apologies if this has been discussed, but I didn't see it during a search.

I have a three-external-display setup running on a MacBook Pro M3. The monitors are all 48" LG OLED B4 TV's. I'm a video editor and switch each day between my home and work offices. The problem is, each time I come home and reconnect, the displays change order, and I have to manually rearrange them back to normal.

I know BetterDisplay has a Layout Protection feature. But my monitors all appear as the same make, model, and serial number to macOS.

Is there a way to make a unique ID for each display so I can make the Layout protection work correctly? Or am I missing something else?

Note: at work, I have three of the same 32" Dell monitors, but the OS always keeps them in the same order even without BetterDisplay.

Yeah, this is an issue. The app has an option to quickly switch two identical displays but this does not work for 3 identical displays. I don't have an easy solution for this. You can use the app's CLI and reposition displays that way, maybe creating a script for the common scenarios.

For the Dell displays their serial or alphanumerical number might be different?

With the latest v3.3.2 internal pre-release (enable this under Settings/Applications/Update) one can set the identification method for the displays to "Basic + extended + port". This should (in theory) make the app identify a display as a specified display only when it is attached to a specific port. This will not solve the macOS mixing the displays up but at least the app should not mix them up. This might not work well with docks and will not work with non-natively connected displays.
