Arrangements - any way to keep them.

[udingmyride]

Hi there, have a 2016 MBP.

I run 2 external monitors via HDMI and use the 13" display as 3rd monitor. I have an arrangement setup - however every morning when I plug the monitors in the 2 external montiors "swap" - so I have to go in to display settings and swap them over.

I keep the same ports plugged in the same way every day and plug them in before turning on the MBP, however the way the montiors show up seems random. It's really really annoying.

Anyone have an ideas how I can lock a monitor to stay in the same place???

Thanks.

I can't vouch for this, but it may be worth a try (though I'd recommend moving instead of deleting the preferences file). From http://troikatronix.com/troikatroni...1/yosemite-monitors-out-of-order-after-reboot

Ok, the initial indications from the theater in NYC who I am working with to solve this problem are this:

Michel is a genius. ;-) Because I believe his advice was the key to the solution.

Well, OK.. they are still going through the process of rebooting ten times to a really see if the projector order stays the same. I will report back to let you know if this test succeeded or failed for them.

Here's what we did:

1) Go to ~/Library/Preferences/ByHost/
2) Delete the file com.apple.windowserver.XXXXXXXX... (the XXXXXX part is quite long and will be different on every machine.) This file holds the display order you've defined previously in the Displays panel of the System Preferences. (Note that any previously saved setups will be lost because of this.)
3) Reboot
4) Now – from this point forward – never reorder your monitors in the Displays panel of the System Preferences. Instead, you need to physically reorder your cables so that the right image shows up on the right projector/display
5) Label everything and write down how they are plugged in to the computer, because the cable order is obviously critical now; you can just reorder it in software.

I hope that helps someone out with this very annoying problem. (Thanks to @k8tefree her help in sorting this [hopefully] out.)

Best Wishes,
