WinDisplayManager

DDC/CI monitor control for Windows: brightness, contrast, input switching, power mode, hotkeys, and display profiles, all from a native GUI.

Features

• Brightness & contrast control over DDC/CI, per monitor.
• Input source switching (HDMI, DisplayPort, etc.) from the monitor page or a hotkey, using the inputs each monitor advertises.
• Power mode control to put monitors into standby or turn them off with a hotkey, or sleep all displays from the tray.
• Global hotkeys with configurable action chains: one shortcut can run several actions at once (set or offset brightness/contrast, switch inputs, change power mode, write custom DDC/CI VCP codes, apply a profile, or turn displays off), each targeting all displays or specific monitors. Configurable entirely in-app.
• Display profiles to save and restore whole monitor layouts (resolution, position, orientation) via Windows CCD, switchable instantly or by hotkey.
• System tray integration: closing the window keeps the app in the tray, with quick access to profiles and turning displays off. Optionally starts with Windows, minimized to the tray.
• Native GUI built with libcosmic/iced.

Installation

Download the latest windisplaymanager_rs-*.exe from the Releases page and run it. It's a single portable executable, no installer needed.

The executable isn't code-signed, so Windows SmartScreen may warn you on first run. Click More info → Run anyway to proceed.

Monitors must have DDC/CI enabled in their on-screen menu. Settings are stored in %APPDATA%\windisplaymanager\config.json; see Configuration & recovery.

Building from source

Requires a recent stable Rust toolchain (edition 2024) on Windows.

cargo build --release

The binary is produced at target/release/windisplaymanager_rs.exe.

To publish a GitHub Release, tag v plus the Cargo.toml version and push that tag. The steps are in the testing runbook.
