The recently released action role-playing game, Fallout 4 has become extremely popular. It is available for PC and game consoles. On PC, it has a number of issues you might face. One of the issues is missing support of 4:3 screens. The game does not offer any option to select a usable resolution for screens with 4:3 aspect ratio to run it fullscreen. Here is what you need to do to run Fallout 4 fullscreen on a 4:3 display:

1. Close the Fallout 4 game.
2. Go to your game preferences folder. Usually it is located at:This PC\Documents\My Games\Fallout4

   If you are running Windows 7, go to

   C:\Users\your user name\Documents\My Games\Fallout4
3. Double click the file Fallout4Prefs.ini. It will be opened in Notepad:
4. Find the line starting with bFull Screen= Change it tobFull Screen=1
5. Next, find the line starting with iSize H= Change it to the height of your screen. For example, for 1280 x 1024 display resolution, it isiSize H=1024
6. Find the line starting with iSize W= Change it to the width of your screen. For example, for 1280 x 1024 display resolution, it isiSize W=1280
