Step-by-step instructions
- Check Windows HDR mode and the display's on-screen menu.
- Open Twinkle Tray Monitor Settings.
- Inspect available SDR and HDR brightness controls.
- Test the lowest safe brightness first.
Why this matters
Advanced monitor features should be tested in small, reversible increments. Keep a note of original settings before changing any display firmware-facing control.
HDR displays may expose brightness differently from SDR monitors, so the available sliders depend on how the display reports supported controls. This procedure is relevant to twinkle tray hdr 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
Start from a known state and verify that the selected display—not another monitor—received the intended command.
