BrightnessTray is a simple utility for Windows which lets you control your laptop screen brightness, right from your system tray.

Use your mouse/scroll wheel!

Extra features

  • Power off the laptop screen, and any connected monitors if possible.
  • Sleep mode shortcut.
  • Enable ‘Caffiene’ mode to keep the monitor from turning off during idle. My maths stats tutor could really use this.
