Fallout 4 Message Board  

With a friends help I got this for 4:3 support:

How to add 4:3 support.
Note: this is essentially the same fix as is present for 21:9. But just so it is explicit I have put it in its own section.

To have this game run in 4:3 simply open Fallout4Prefs.ini in your documents (C:\Users\[name]\Documents\My Games\Fallout4\), and change the following lines to how they are below:

For borderless windowed mode:
bTopMostWindow=1
bMaximizeWindow=1
bBorderless=1
bFull Screen=0
iSize H=XXXX
iSize W=YYYY

Where XXXX is whatever your vertical resolution is aand YYYY is whatever your horizontal resolution is.

For fullscreen mode:
bTopMostWindow=0
bMaximizeWindow=0
bBorderless=0
bFull Screen=1
iSize H=XXXX
iSize W=YYYY

Where XXXX is whatever your vertical resolution is aand YYYY is whatever your horizontal resolution is.

Next do the same for the second Fallout4Prefs.ini located in wherever you insalled steam then steamapps\common\Fallout 4\Fallout 4.

Currently the hud will not work correctly, but this is a good start and hopefully the hud can be fixed (i'll look into it).

Al stick to 1080p widescreen. never had a problem with any game. Bar old ones that need to be modded from way back. So I supect al be fine with FO4.
