I can't for the life of me figure out how Windows 10 prioritises my screens. I have what I consider to be my main monitor straight in front of me connected through a DVI connection, I have a smaller screen off to the left connected through VGA->DisplayPort and I have a TV on my wall to my right connected through HDMI. Windows 10 likes to see the screen in front of me as my "3rd Screen", so when I press Win+P and select 'PC Screen Only' it overrides any settings on which is my main display and will display through the VGA->DisplayPort monitor. If I select "2nd Screen Only" from that menu, it defaults to the TV, which is turned off 90% of the time... To get it to display only on the screen straight in front of me I need to go into the control panel and disable the other two. Is there no way I can force Windows 10 to accept that the screen in front of me should be Screen 1, have my smaller monitor be Screen 2 and the TV be Screen 3? To be clear, I'm not asking about re-ordering them in Display Settings, I'm asking about re-ordering the way Windows prioritises which is which. See this for what I mean.
