Step-by-step instructions
- Open the brightness flyout.
- Confirm at least two displays are detected.
- Turn on the link-all feature.
- Move the linked control and compare each monitor.
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.
Linked brightness controls let you move multiple supported monitors together instead of adjusting each one manually. This procedure is relevant to twinkle tray link monitors 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.
