Playing Monster Hunter Stories 3: Twisted Reflection on an ultrawide monitor can be frustrating because the game defaults to a 16:9 aspect ratio, which results in black bars or missing resolution options on wider displays. Players using monitors such as 3440×1440 or 5120×1440 may notice that the game doesn’t properly scale to their screen.
Luckily, the PC community has discovered a workaround using REFramework, a popular tool for games built on Capcom’s RE Engine. This mod can help you unlock ultrawide resolutions and fix some common FOV issues. In this guide, you’ll find step-by-step instructions for installing the MHS 3 ultrawide fix.
Monster Hunter Stories 3 Ultrawide Fix (REFramework Method)
The current workaround involves installing REFramework Nightly, which allows the game to bypass the default aspect ratio restriction. Make sure to only go ahead if you understand the technicalities, understand the risks and have the original backup saved.
Here’s how to do it:
- Download the latest REFramework Nightly build.
- Extract the downloaded archive.
- Copy the file dinput8.dll into the Monster Hunter Stories 3 installation folder.
- Launch the game normally.
- Open the REFramework menu in-game.
- Head to Graphics settings.
- Enable the Ultrawide options.
According to the guide, only the dinput8.dll file is required in the game folder for the fix to work.
Recommended REFramework Settings
To avoid common issues like zoomed-in visuals or stretched UI, enable the following settings (shared via Steam Community).
- Enable Vertical FOV – prevents the camera from zooming in when using ultrawide resolutions.
- Constrain UI to 16:9 – prevents menus and UI elements from stretching across the screen.
Supported Ultrawide Resolutions
Once the fix works correctly, players can run the game at resolutions like:
- 2560×1080 (21:9)
- 3440×1440 (21:9)
- 3840×1600 (21:9)
- 5120×1440 (32:9)
Your available resolutions may vary depending on your GPU and monitor.
How to Hide the REFramework Menu
If you don’t want the REFramework menu appearing every time you launch the game:
- Open the REFramework menu.
- Go to Configuration.
- Enable Remember Menu Open/Closed State.
- Close the menu.
- After doing this, the overlay will stay hidden when the game starts.

Known Issues
At the moment, the ultrawide fix may not work correctly with the full retail version of the game. Players have reported that the game can crash shortly after launch, and the mod currently works more reliably with the demo version. Community members suggest that this happens because of anti-tamper protection, which prevents the mod from loading properly. The REFramework developer has shared that support for the full version may arrive in a future update.
Should You Use the Ultrawide Fix?
If you play on an ultrawide monitor, the fix can significantly improve the experience by:
- Removing black bars
- Increasing horizontal view space
- Making exploration and combat feel more immersive
However, because it relies on a mod, you may need to update or reinstall the fix whenever the game receives patches.
