This question already has an answer here:

When running two external monitors in OS X Sierra, my dock sometimes changes which display it is located on. Is there a setting to stop this from happening? This happens at random times, and I can't reproduce the issue.

  • Brian, please be more specific. When does it switch screen? Is there any time in particular? Please give more details. – YusaMac205 Aug 3 '17 at 17:15
  • It's totally random. Happens to me every week or so. – DraganAscii Aug 3 '17 at 17:17
  • Do you unplug your external monitor a lot? – YusaMac205 Aug 3 '17 at 17:18
  • Yes but mostly at the end of the work day. Not the power cord, but the display adaptor (thunderbolt?) – DraganAscii Aug 3 '17 at 17:19
  • So the dock switches monitor about every week? – YusaMac205 Aug 3 '17 at 17:23
