What Twinkle Tray is
Twinkle Tray is a free Windows utility for controlling brightness across multiple monitors from a system-tray icon. Sliders can change one display or all displays together, and the app can adjust DDC/CI features such as contrast, volume, and power state. It works with most laptops and DDC/CI-enabled monitors, using WMI for internal laptop displays and DDC/CI for external displays. Brightness changes can be scheduled by time of day or computer inactivity, and hotkeys can target individual displays or all of them. Command-line arguments allow custom scripting, and the application is localized in over 20 languages. It is available through the Microsoft Store or as a GitHub installer. Some VGA or DVI connections, along with certain USB, Thunderbolt, or Surface docks using HDMI or DisplayPort, may not be compatible. 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; the policy says collected details are stored in Google Analytics and not shared with other third parties.
