Summary :

There’s some necessary details missing in this question. I’ll cover two possible options. Question as of 4 Jan 2019: I used Fallout 4 SE once and it was fine but when I launched it a second time, it launched regular fallout 4. I installed the latest f4se build and set it to launch through MO2. Before I launched it, I launched the normal Fallout 4 via Steam, everything was working fine and it launched on the right monitor. However, when I launched f4se via MO2 after making sure the base game was working, it launched on the wrong monitor.

• I do have f4se installed and all I did was drag everything into the Fallout 4 dir and rename Fallout4Lancher.exe to Fallout4Lancher.exe.bak and f4se exe to Fallout4Lancher.exe. In game f4se will give a version number and even shows as f4se in the pause menu, so I don't think that's wrong.
