Fallout4 – set a non standard display resolution

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 that you have a very limited list of pre-defined display resolutions. If your native display resolution is not listed in the game preferences, here is how you can set it.

  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 bTopMostWindow=
    Change it to
    bTopMostWindow=1
  5. Find the line starting with bMaximizeWindow=
    Change it to
    bMaximizeWindow=1
  6. Find the line starting with bBorderless=
    Change it to
    bBorderless=1
  7. Find the line starting with bFull Screen
    Change it to
    bFull Screen=0
  8. Find the line starting with iSize H=
    Change it to the height of your screen. For 1600 x 1200 display resolution, it is
    iSize H=1200
  9. Find the line starting with iSize W=
    Change it to the width of your screen. For 1600 x 1200 display resolution, it is
    iSize W=1600

That's it. Now you will be able to run Fallout 4 at any desired display resolution.

  2. A complete & utter rip off having been using systems since the dawn of the internet. just making money from gulibles like us. this is a game not a damn convention .

  3. This only half works. It sets the right resolution but the game itself is only on half of the screen and it’s distorted. Sorry if this is something I did wrong but from my stand point it doesn’t work.

  4. It almost works. It looks like I’m missing the bottom 1/4 of my screen, no matter what combination of resolutions I try.

  5. Thank you so much, you’re an absolute lifesaver! I was on the verge of losing my goddamn mind but then I stumbled upon this and now my game doesn’t look like an absolute pile of turd any more!

    Note to anyone who’s tried this and it hasn’t worked: make sure you get the actual resolution right for your screen – the 1600×1200 settings specified in this post may not work for you
