Twinkle Tray: Brightness Slider 1.16.2

Twinkle Tray lets you efficiently manage the brightness levels of multiple monitors.

Even though Windows 10 is capable of adjusting the backlight on most monitors, it typically doesn't support external monitors. Windows 10 also lacks any ability to manage the brightness of multiple monitors. This app inserts a new icon into your system tray, where you can click to have instant access to all compatible monitors' brightness levels.

Twinkle Tray uses DDC/CI and WMI to communicate with your monitors. Make sure you have the appropriate option(s) enabled on your monitor so that it can work with Twinkle Tray.
