Step-by-step instructions

- Use a direct HDMI connection.
- Open the brightness flyout.

Why this matters
Change one variable at a time, then retest. Monitor menus, cables, adapters and graphics drivers can all affect display-control behavior.
HDMI commonly works with DDC/CI-capable displays, though particular capture devices and adapters may interrupt communication. This procedure is relevant to twinkle tray hdmi on Windows 10 or Windows 11. Avoid assuming that settings on one display will apply identically to another model.
How to verify the result
Retest the exact scenario that failed originally, then document the cable, monitor model and software version if the problem continues.
