Twinkle Tray: Brightness Slider is a free Microsoft Store application for Windows devices that allows you to control the brightness of all connected monitors individually.
While designed with multiple monitors in mind, Twinkle Tray works fine on single monitor systems as well.
Twinkle Tray: Brightness Slider is a modern app for Windows 10 and 11 devices. It is an open source application that is available on GitHub and the Microsoft Store. Windows Package Manager users can install it with the command winget install twinkletray.
Twinkle Tray adds an icon to the system tray of the Windows operating system on start. A click on the icon displays a brightness slider for all connected displays. The displays need to support DDC/CI and WMI for communication, which most do.
The style of the interface matches the personalization settings of the user and the style of the Windows version.
