✨ Key Features
📊 Pros & Cons
✅ Pros
- Massive community trust with 2,062 endorsements and 425k downloads.
- Actively maintained — last updated January 2026.
- Works with the big UI overhaul mods, so you don't have to choose.
⚠️ Cons
- Only fixes UI scaling — no extra features or customization.
- Requires a 21:9 monitor to be useful; useless for standard 16:9 setups.
For ultrawide monitor owners who are tired of stretched or broken UI elements in Fallout 4. If you're running 21:9 and use mods like FallUI or DEF_UI, this is a must-have. Skip if you're on a standard 16:9 display.
💡 Beginner Tips
- Make sure your monitor is actually set to 21:9 in Windows before launching the game.
- If you use a mod manager like Vortex, install this mod and let it overwrite any conflicting UI files.
- Test in a variety of menus (Pip-Boy, workshop, dialogue) to ensure everything scales correctly.
