Download Twinkle TrayAbout Twinkle Tray

These are two separate applications. Both download directly from this site.

Before you download

  • Check that your Windows version is listed as supported on the official site.
  • 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

  1. Look for the new icon in the notification area near the clock.
  2. Open the panel and confirm each display is listed.
  3. Drag a slider and check the picture responds.
  4. Set up keyboard shortcuts if you want brightness keys on a desktop.
  5. 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.

Frequently Asked Questions

Where should I download Twinkle Tray from?

Straight from this site — press Download on our [Twinkle Tray download page](/twinkle-tray-download) and the file starts immediately.

Does the download cost anything?

Twinkle Tray is free and open source. Refer to the official site for the current licence.

Do I need to uninstall other brightness tools first?

It is worth doing. Two utilities sending brightness commands to the same monitor can fight each other and produce jumpy results.
