Twinkle Tray is a Windows system tray application that enables brightness control for external monitors.
Windows lacks native support for adjusting external monitor brightness and provides no interface for managing multiple displays. Twinkle Tray solves this by placing brightness sliders in the system tray, accessible via a single click. The tool communicates with compatible monitors using DDC/CI protocol to adjust backlight levels. It also supports controlling other DDC/CI features such as contrast, and can normalize brightness across different monitors to ensure consistent levels.
The tool suits anyone running Windows 10 or 11 with multiple external displays who wants quick access to brightness adjustment without diving into monitor settings menus. It works best with DDC/CI-compatible monitors, though compatibility varies by manufacturer and model. The application integrates with Windows personalization settings, automatically matching your taskbar theme and appearance. Beyond basic brightness control, the tool offers scheduling features to automatically adjust brightness based on time of day or idle status, hotkey binding for quick adjustments, and automatic startup with Windows.
Development activity shows consistent maintenance with regular updates addressing user needs. The project maintains active translation support through community contributions. Package availability through multiple distribution channels indicates ongoing effort to reach users through their preferred installation methods. The codebase uses JavaScript with React for the interface and Electron for the desktop application framework, suggesting a focus on maintainability and cross-version Windows compatibility.
