Twinkle Tray
What it is
Twinkle Tray is a Windows utility for managing brightness across multiple displays from the system tray. Its sliders adjust one display or all displays together, and it can control DDC/CI monitor 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 screens. Brightness adjustments can be scheduled by time of day or computer idle state, and hotkeys can target particular displays or all of them. Command-line arguments support custom scripting, and the app is localized in over 20 languages. It is free, with a Free plan listed as free, and is available through the Microsoft Store or as a GitHub installer. Some VGA or DVI connections and certain USB, Thunderbolt, or Surface docks using HDMI or DisplayPort may not be compatible. Its privacy policy describes Google Analytics collection of settings, operating-system and interaction details, CPU name, app version, and estimated location, with an opt-out in Settings.
