Resolution issues with Fallout 4

[Sashi]

I accidentally reset my display settings when launching the game and now it won't fit my screen at all. Full screen is too big and can't fully be seen, and windowed/borderless is too small no matter what setting I put it on.

It only gives me two options on the launcher.

Aspect Ratio 16:9 with no options under resolution
Aspect Ratio 16:10 with 1024x640 and 800x500 as the only options under resolution.

Before this issue, there were many more options.

My resolution is 1024x768 and my display size is Medium. I have to have it medium because I'm visually impaired and it becomes a strain to see it on smaller. I'm running windows 7 and my graphics card *will be replaced soon because it sucks* is Nvidia Geforce GT 720.

I know my card sucks but I would still like to be able to play this game while I save up the money to replace it.

in documents\my games\fallout4prefs.ini find lines like this and set them accordingly:
iSize H=1024
iSize W=768

That doesn't seem to work. :/

Try enabling display scaling. I had a similar problem when playing Penumbra where the image was bigger than the fulscreen and this fixed it.
Rightclick fallout4.exe in steam/steamapps/common/fallout4, select compatibility and then untick "Disable display scaling on high DPI settings"

its grayed out and un-ticked. I don't even have the option to tick it.
