game auto goes onto my vertical monitor then when i try to change it to my main it doesnt let me then when i finally set it to the resoluution on my main monitor it shrinks to a really small display which covers the save button so i cant apply the fullscreen settings
Try to use command line arguments:

And if you need to reset all settings, then hold keys R and P for 5 seconds on login screen. Game will auto close.
