I have a pair of the same model and size monitors at home, as I have in the office. They're all named "Company Model (1)" and "Company Model (2)".

It seems like the setup I have at home has them physically arranged from L -> R: 1 -> 2, but in the office, however, it's 2 -> 1.

The result is when I work from home, or work from the office, I need to constantly set the Display Arrangement in Preferences.

Is there a way to delete the displays, so I can reintroduce them to the computer in the right order, or just rename them so the one physically on the left is always 1, and the one on the right is always 2?

  • I could theoretically delete the Displays in .GlobalPreferences.list, but I'm worried about breaking the file.

  • Couldn't you just take the two displays in either location and switch their physical ordering so that the computer's understanding is correct? Or am I missing something... Oct 13, 2017 at 18:56
  • @ToddDabney We're all missing something, because I did exactly that, and it doesn't seem to matter. I thought it had to do with the naming, but there seems to be some weird configuration based on assumptions that you're never going to have the same make and model of monitors in two different places.

  • Do I need to reset the pram or smc or something maybe, then plug in the monitors in the same order from location to the other?

  • Spencer I'm not understanding how what you're describing is possible. What you stated originally was that it was consistently one way at home and the opposite way at the office. So switching the monitors would easily solve this, but you're saying that when you switched the physical location of the monitors they then started consistently showing up in the opposite orientation, leaving you with the same problem?

It turns out it's the dongle with which the monitors are connected. I have two different brands (Satechi and Anker) at home, and (Apple and Anker) at work. When I plug the monitors into the different dongles, it changes orientation. The reason the physical swap didn't work, was because I also unplugged the cables from the monitors in the office, and reconnected them to the different dongles. I tried unplugging the monitors from the dongles at home and swapping them, and and they indeed switched.

This is probably the most trivial of information, but it's at least answered!
