2022, how in the flip has nobody done this? I had to google the flipping fix myself and after searching the Nexus saw nobody did this ... HOW!? What are we doing guys? ZZzzzzzZZZzzzz we sleep on these.
Here's the quick fix for anybody wanting to do this on their specific monitor.
INSTALLATION:
- drop this .ini into your MO2/Vortex or any other mod organizer software's folder
(I use MO2 for me it's mo2 directory you set up for the game\profiles\Default)
- if you're not using any mod organizers then the default locations should be Steam\steamapps\common\Fallout 4\Fallout4
- replace the .ini in Documents\My Games\Fallout4 for extra safety
The downloads only help me earn points on Nexus, they are not mandatory, you can do it yourself in your own files.
Configuring lines in the .ini files
bTopMostWindow=0 (by default it's probably 1)
bBorderless=0 (by default it's probably 1)
bFull Screen=1 (change this to 1 to have the flipping game boot in full screen)
iSize H=use your own(1440 for mine)
iSize W=use your own(2560 for mine)
Additionally you can change fallout4custom.ini to be like this for extra measures:
iLocation X=0
iLocation Y=0
(both will have different values by default probably, mine were
A compact bug fix for Fallout 4 that resolves the windowed mode display issue when launching the game through F4SE. With 297 endorsements and nearly 10k downloads, it's a community-tested solution for a common annoyance, though it hasn't been updated since July 2022.
✨ Key Features
📊 Pros & Cons
✅ Pros
- Community-approved fix (297 endorsements) for a common F4SE launch issue
- Lightweight and focused—does exactly one thing without bloat
- Solid download count (9,857) shows real demand for this fix
⚠️ Cons
- Outdated—last updated July 2022, may not work with newer F4SE or game versions
- Potential conflicts with other mods that alter display settings or F4SE behavior
- Limited scope—only addresses windowed mode, not other launch issues
For Fallout 4 players who launch through F4SE and are tired of the game starting in windowed mode. If you're on an older game version and F4SE build, this is a quick fix. Skip if you're on the latest updates—it may be outdated.
💡 Beginner Tips
- Make sure you have F4SE installed and launch the game through its loader, not the default launcher, for this fix to apply.
- If you're using a mod manager like Vortex or MO2, install this mod and enable it in your load order—it's a simple plugin.
- Check your Fallout 4 and F4SE versions; if they're newer than 2022, this fix might not work and you may need an alternative.
