Keep in mind, that this is NOT about moving which monitor is left, right, up, down and which is the MAIN monitor.
This is about switching identity numbers of the monitors.
I've seen many threads on this, all of which where horribly wrong.
I have 3 monitors hooked up. I have the laptop screen (1) and two large display port monitors (2 and 3).
This setup is the same at my office and at my home. I had a problem where my home setup reversed monitor identities for 2 and 3.
When this occurred, I would put my laptop into sleep mode and go into the office. When I got into the office, put my laptop into the dock and opened it, all my open windows would be open in the opposite monitors.
The question was "how did my monitors, at home, get reversed?"
The answer is that one of them was unplugged for a short time.
The fix is the same. Unplug big monitor (right side). The big monitor (left side) now becomes monitor 2 again. Plug in the big monitor (right side) and it now become monitor 3 again.
This fixed the issue and I am back to normal.
