What it is

Twinkle Tray is a Windows utility for managing brightness on multiple monitors from a system-tray icon. Sliders can adjust one display or all displays at once, and the app can control DDC/CI monitor features such as contrast, volume, and power state. It supports most laptops and DDC/CI-enabled monitors, using WMI for internal laptop displays and DDC/CI for external displays. Users can schedule brightness adjustments by time of day or when the computer is idle, and bind hotkeys to particular displays or all of them. Command-line arguments support custom scripting, and the application is localized in over 20 languages. Twinkle Tray is free and can be obtained through the Microsoft Store or as a GitHub installer. Compatibility may be limited with VGA or DVI connections and some USB, Thunderbolt, or Surface docks using HDMI or DisplayPort. Its privacy policy describes collection of settings, operating system, CPU name, app version, user interactions, and estimated location through Google Analytics; users can opt out in Settings.
