WINDOWS 10 FULLSCREEN FIX

[Wasabi]

After multiple trial & error attempts, researching different forums with no resolve, i found a fix!

I'm running on Windows 10 with display resolution of 1920x1080 (read below as the resolution will be different when changing it in your settings).

Open up the file: (Fallout4Prefs) from BOTH of these areas:
- Pc\Documents\My Games\Fallout4
AND
- From your Steam Folder > Steamapps\Common\Fallout4\Fallout4
(I opened these files with notepad)

Now scroll down till you find this area and change the values to match whats listed below:

bTopMostWindow=0
bMaximizeWindow=0
bBorderless=1
bFull Screen=1
iSize H=2160
iSize W=3840



- Make sure to do this on both Fallout4Prefs files then SAVE.

Sidenote: Under the (Steam Folder > Steamapps\Common\Fallout4 ) i right-clicked on both the Fallout4 application & the Fallout4launcher & selected Properties>Compatibility> Checked the box for "Run as an administrator". Also under Properties I selected the 'Security' tab , selected "Edit..." and turned on "Full Control". Only try this as well if the instructions above do no fix the issue.

HOPE THIS HELPS!!!

Guys, I just fixed the problem completely different way, because for me the problem was not in the wrong settings of .ini file but in the system's "documents" folder which wasn't at default location due to superb help of Microsoft's OneDrive software. The path to it will be going through the OneDrive (if it was ever installed at your machine, which I bet it was) which mess the things around. Basically, the game couldn't use the settings of game's config because it couldn't see it. To fix that you would need to play around the registry structure and change a few keys manually but I already found everything 4 you, so long story short, just follow the simple instructions and enjoy the full screen after :)
This instruction comes from the Microsoft support site so don't worry, it's completely safe to use.

We need to create a .txt file (anywhere, you can use your desktop) open it and put in the following below:

@echo off

taskkill /f /im explorer.exe

timeout /t 2 /nobreak >nul

if not exist "%UserProfile%\Documents" mkdir "%UserProfile%\Documents"

reg add "HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders" /v "Personal" /t REG_SZ /d "C:\Users\%USERNAME%\Documents" /f

reg add "HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders" /v "{f42ee2d3-909f-4907-8871-4c22fc0bf756}" /t REG_EXPAND_SZ /d %%USERPROFILE%%"\Documents" /f

reg add "HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders" /v "Personal" /t REG_EXPAND_SZ /d %%USERPROFILE%%"\Documents" /f

attrib +r -s -h "%USERPROFILE%\Documents" /S /D

timeout /t 1 /nobreak >nul

start explorer.exe

To make it work, after you save the .txt file you have to change it's extension to .bat to make it runnable as a script. After that just run it, it will complete all the tasks and close itself. That's it, the game will run Full Screen now if you set it that way in Launcher options.

P.S.
for those who have no idea how to make a file extensions visible, go to "search" at your system, look for the "File Explorer Options", go to "View" page and tick off "Hide extensions for known file types"


I've spent half a day to find this fix, but finally it worth it.
Enjoy ;)

Alonts, mate, you are a lifesaver. I can not thank you enough, you fixed all my problems. Thank you

[морф с тупорылым ником]

Alonts, oh my god, thank you, it did help

[Alonts]

No worries, guys! :)
I hope this will become a well known trick and will be used as a manual on "how to" for anyone who have the same issues with old games, I tried so many things before I realized that the problem is not a permissions, security, .ini file setup etc...
FYI, this trick actually also fixed my issue with "not enough HDD space" problem of a good old Max Payne 3 - runs as it should now^^
It's really frustrating that neither a Steam, nor a Rockstar Games publishers have no clue on this fix and it's damn difficult to find it. They still selling the products but then you got no support...
Microsoft is kinda aware of it but there is no such an article regarding an old games issues, I found this following another problem but similarity of the issue made me think it's gonna work for me too - so it was completely worth trying :)

man, you're a real lifesaver! Thank you for this advice, cause, as I really suspected, the problem was not in the ini files -- I've changed them 100 times, so thank you one more time!

[Alonts]

Not a problem, bro!
After that trick worked for me I felt like I really want to share this thing with as many as possible "victims" of that One Drive thing, cause it was such a relieve to see the things running as they supposed to - I simply couldn't enjoy that alone^^!
P.S.
I tried the same thing on different machine running on Win11 - works same way! So have no fear, it will still work - same file structure :)

question why is no full screen... I play F4 for over 1700 hours only in full screen...

Check drivers and not from the manufacturer of the hardware but of the chips...

AMD
Nvidia
Intel

Here is a pretty good site to check drivers:

https://www.intel.de/content/www/de/de/support/intel-driver-support-assistant.html

that should show if drivers are outdated for graphics cards had to be checked at

AMD : https://www.amd.com/de/support

Nvidia : https://www.nvidia.de/Download/index.aspx?lang=de

have to find the right ones...

and settings Optimal for Fallout 4 findeste here:

https://www.gamer83.de/stellst-du-deine-grafik-fallout-4-ein/

otherwise... yes ka what is your problem
