STEPS TO REPRODUCE

Enable Night Color in System Settings.

Set a schedule for day/night mode.

Connect multiple monitors and observe color temperature changes during scheduled times.

OBSERVED RESULT
Night Color sometimes does not activate on secondary monitors, or the schedule triggers inconsistently.

EXPECTED RESULT
Night Color should automatically adjust the color temperature on all monitors according to the set schedule.
