How to get Fallout 4 to work on an ultrawide monitor?
Getting Fallout 4 to play nice with an ultrawide monitor takes a bit of tweaking, but it's totally doable. First, you'll need to dive into the Fallout4Prefs.ini file located in your Documents/My Games/Fallout4 folder. Change the 'bTopMostWindow=1' to 'bMaximizeWindow=1', and then adjust the 'iSize H=' and 'iSize W=' to your monitor's resolution. Don't forget to set this file to read-only after making your changes to keep the game from resetting your hard work. Also, consider grabbing the 'Ultrawide Interface' mod on Nexus Mods to fix any stretched menus and HUD.

Just set your game to windowed borderless mode in the settings. It's not a perfect fix but it works for some without having to mess with game files.
Honestly, messing with .ini files and mods sounds like a hassle. Why not play the game as intended on a normal monitor?
