These are two separate applications. Both download directly from this site.
Before you download
- Confirm you are running Windows 10 or Windows 11 on a 64-bit PC.
- Note whether you want the classic installer or a Store-style package, if both are offered.
- Confirm your monitor is connected directly rather than through an untested adapter.
- Enable DDC/CI in the monitor menu if the option exists.
After installing
- Look for the new icon in the notification area near the clock.
- Open the panel and confirm each display is listed.
- Drag a slider and check the picture responds.
- Set up keyboard shortcuts if you want brightness keys on a desktop.
- Enable start with Windows so the tray icon is always available.
If a display does not appear
Missing displays are almost always a hardware path issue rather than an application bug. Work through fixing external monitor brightness on Windows, which covers cables, docks, monitor menus and drivers.
Looking at the alternative
If you prefer an application installed and updated through the Microsoft Store, see the Microsoft Store brightness control app or the comparison page.

No. Twinkle Tray is free and open source.
Which Windows versions does it support?
Windows 10 and Windows 11. It controls the internal laptop panel as well as external monitors that support brightness over DDC/CI.
