Windows night light not working
Jul 29, 2025 am 05:34 AM
Night mode cannot adjust the color temperature or does not take effect, which is usually caused by system settings or driving problems. First check whether night mode is actually enabled: go to Settings > System > Display, confirm that the "Night Mode" switch is on. If the gray is not selected, it may be a problem with the graphics card driver or system version; secondly, if the color temperature adjustment is invalid, you can try restarting the Explorer, use the registry to repair, reset the night mode settings, and turn off the conflicting third-party software; finally check the time and geographic location permissions: Ensure that the location is allowed in the privacy settings, and enable the automatic time and time zone setting function.
