- Open the Twinkle Tray tray panel.
- Identify each display by its reported name.
- Move a single monitor slider first.

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.
Twinkle Tray shows separate controls for compatible monitors in one Windows tray panel, with optional linked adjustments. This procedure is relevant to change brightness multiple monitors windows 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.
