AutoRes

Switches your monitor to a game's resolution while the game runs, and switches back when it closes.

Handy for stretched resolutions (e.g. 1728×1080 in Overwatch, 1440×1080 in Valorant) without touching Windows display settings every time.

Features

• Automatic switching: detects when a saved game starts and applies its resolution, then restores your desktop resolution when it exits
• Game profiles: one resolution per game; pick it from the running programs list or browse to its .exe
• Supported modes only: resolution dropdowns list what your monitor actually supports
• Runs in the tray: left-click to show/hide, right-click for Open / Exit
• Start with Windows, start minimized, close-to-tray
• Light and dark mode, including a dark title bar
• Safe switching: the game resolution is applied temporarily, so a crash or reboot never leaves you stuck on it

Download

1. Grab the .zip from the latest release
2. Extract it anywhere and run AutoRes.exe

Requires Windows 10 or 11 with .NET Framework 4.8 (already included in Windows).

How to use

1. Desktop resolution: pick your normal resolution (or click Use current) and click Save.
2. Add a game: start the game, click ↻ and pick it in Program, or type its process name, or use Browse… to select its .exe. Choose a Resolution and click Save game.
3. Play: the status in the top right turns green and shows the active game. Close the game and your desktop resolution comes back.

Click a profile to edit it, or select it and press Remove / Delete.

Build from source

Requires the .NET SDK or Visual Studio 2019+.

git clone https://github.com/kuhmori/AutoRes-Monitor-Resolution-Switcher.git
cd AutoRes-Monitor-Resolution-Switcher/AutoRes
dotnet build -c Release

The exe ends up in AutoRes/bin/Release/. On Windows you can also just double-click AutoRes/build.bat.

Troubleshooting

Problem	Fix
"isn't supported by this display"	Choose a resolution from the dropdown; your GPU/monitor doesn't offer the one you typed. For custom stretched resolutions, add them in NVIDIA/AMD/Intel control panel first.
Resolution doesn't change	Check the process name in Task Manager → Details (without .exe). Some games run under a different exe than their launcher.
Game resets the resolution	Set the game itself to fullscreen at the same resolution, or borderless.

Settings are stored in %APPDATA%\AutoRes\settings.xml.
