Can you change your laptop brightness with one key, but not your external monitors? Twinkle Tray is a free, open-source brightness tool for Windows, and this guide covers the twinkle tray download for pc, the official source, and a step-by-step install. You will learn what Twinkle Tray does, what your PC needs, and how to adjust your first monitor in minutes.
What Is Twinkle Tray?
Twinkle Tray is a free, open-source app that adds brightness sliders for every monitor to the Windows system tray. Windows can dim a laptop screen, but it offers no slider for external monitors. Twinkle Tray fills that gap, so you no longer need to press the buttons on each monitor.
It talks to external monitors through DDC/CI, a standard channel that lets software change hardware settings. Laptop screens are handled through Windows Management Instrumentation (WMI). The app is built on Electron and published under the MIT licence, with builds on its website, GitHub, and the Microsoft Store.
One slider appears for each screen, and you can move them one by one or link them together. It also adds hotkeys, time-of-day schedules, and a tool that evens out brightness across different monitor models. It runs only on Windows 10 and 11, and it stays quietly in the tray until you need it.
Key Features
- Per-monitor sliders: one brightness slider for each display in a tray flyout like the volume control.
- Link monitors: move all sliders together, or adjust one screen on its own.
- Hotkeys: raise or lower the brightness of one display, or all of them, from the keyboard.
- Time-of-day schedules: change brightness automatically at set times of the day.
- Idle dimming: dim your screens when the PC has been idle for a while.
- Backlight normalisation: even out brightness levels across monitors of different models.
- DDC/CI extras: adjust contrast and volume where supported, plus command-line control for scripts.
System Requirements
- Operating system: Windows 10 or Windows 11, 64-bit.
- Processor: any modern processor, even a modest one.
- Memory: at least 2 GB of RAM, with 4 GB recommended.
- Disk space: around 200 MB free for the app.
- Monitors: external monitors must support DDC/CI, switched on in the monitor menu.
- Network: an internet connection for the download; the app works fully offline.

- Find the slider for the monitor you want to change.
- Drag the slider left to dim the screen, or right to brighten it.
