I have three monitors (the right most is my main system monitor) and managed to get F4 running on the middle one in windowed borderless.
The screen is 16:10 but I set it to display 1920x1080 (not scaled) in the Nvidia control panel to have a 16:9 monitor.
Now I want to try F4 in non-windowed mode.
The launcher always launches on my main monitor and if I uncheck windowed/borderless, I can't choose my middle monitor as display anymore.
So I'm trying to set this up using the ini files.
I set:
bTopMostWindow=0
bMaximizeWindow=0
bBorderless=0
bFull Screen=1
iSize H=1080
iSize W=1920
in Documents\My Games\Fallout4\Fallout4Prefs.ini and locked it
and in Documents\My Games\Fallout4\Fallout4Prefs.ini
It still launches in borderless/windowed (on the correct monitor though).
How can I launch F4 on my middle monitor (1920x1080) in fullscreen mode (not windowed borderless) using the .ini settings?
