How to Make Fallout 4 Widescreen
Getting Fallout 4 to run in widescreen is pretty straightforward, but you'll need to tweak some game files. First, navigate to your Fallout 4 game folder. Find the 'Fallout4Prefs.ini' file and open it with Notepad. Look for the lines that start with 'iSize H=' and 'iSize W=' and change them to your monitor's resolution. For example, if you're aiming for 2560x1080, set 'iSize H=1080' and 'iSize W=2560'. Save your changes, and you should be good to go. Remember to set the game to run in Borderless windowed mode in the options menu for best results!

Just go to the settings and pick the resolution that matches your screen. Easy peasy.
Honestly, tinkering with game files can lead to weird glitches. Fallout 4 wasn't really designed with ultra-widescreen monitors in mind. I'd stick to the standard aspect ratios to avoid any trouble.
I switched to widescreen by editing the 'Fallout4Prefs.ini' file too! Just make sure you're also adjusting the aspect ratio settings in the game if things look stretched or squished. Worked like a charm for me.
