A Windows desktop app for saving and applying named display + audio profiles. Drag monitors around, enable or disable displays, set resolution and DPI per monitor, and switch between full setups in one click.
Built with Tauri v2 (Rust backend, React/TypeScript frontend).
- Profiles — save your current monitor layout, resolutions, refresh rates, DPI scaling, and audio setup as a named profile, then apply any profile with one click.
- Display layout — drag-and-drop canvas to position monitors. Enable or disable individual displays. Edge-snapping for precise alignment.
- Resolution & DPI — pick resolution and refresh rate per monitor. Set DPI scaling independently per display.
- Audio — set default playback and recording device, volume, and mute state per profile.
- Safe apply — a confirmation banner appears after applying a new layout. If you don't confirm within 20 seconds the previous layout is automatically restored.
- Persistent identity — monitors are identified by adapter LUID + EDID hash, so profiles survive reboots and driver reinstalls even when Windows reassigns
DISPLAY1/DISPLAY2numbers.
- Windows 10 (1803+) or Windows 11
- No runtime dependencies — the MSI installer is self-contained
Download the latest .msi from the Releases page and run it.
