Twinkle TrayStep-by-step instructions
- Choose a comfortable dim level.
- Set a nighttime schedule in the app.
- Adjust Windows Night light separately if desired.
- Test on all connected screens.
Why this matters
For external screens, brightness changes depend on DDC/CI. An on-screen slider cannot override a monitor that blocks or does not implement the relevant protocol.
Reduce screen brightness after dark with a Twinkle Tray schedule; color-temperature tools such as Night light are separate settings. This procedure is relevant to twinkle tray nighttime brightness on Windows 10 or Windows 11. Avoid assuming that settings on one display will apply identically to another model.
How to verify the result
Observe the actual display, not just the position of the on-screen slider. Record any mismatch between the requested level and the visible result.
