Update Display driver

Since it’s a graphics-dependent feature check and make sure the display (Graphics card ) driver installed on your PC is updated with the latest version of the graphics driver installed on your PC.

The best way we recommend is to visit the NVIDIA, AMD, or Intel download portals, then specify your graphics chipset to download the latest drivers.

  • Now right-click on the start menu select device manager,
  • This will display all installed device drivers list,
  • Expand display adapters, Right-click on the current display driver select “uninstall device”
  • Click yes when asking for confirmation then restart your PC to completely remove the driver from your PC,
  • Now install the graphics driver that previously you downloaded from the manufacturer’s website.
  • Again Restart the Windows, Now click on the action center and enable night light.

Pro Tip: If you don’t know the exact make and model of your chipset, you can use utilities such as NVIDIA Smart ScanAMD Driver Autodetect, or Intel Driver Update Utility to help you out in that regard.

Update clock settings and Location

Well if you have a scheduled night light to turn on night time only but Night Light keeps on staying enabled even outside the time that it’s scheduled to actually run in such cause you need to check your time zone or update clock settings and enable Location as well.

  • Open settings then click Time & Language,
  • On the left-hand side, click Date & Time then make sure the set time and set time zone automatically toggle is turned on.
  • Also, scroll down and check the correct time zone is selected
  • Now move back to the settings home screen,
  • Click Privacy then Location
  • Here make sure the Location for this device is Turn on

In case, if the problem is not solved it’s best to switch to Night light alternatives like F.LUX or Sunset Screen.
