Night Light feature not working after updating to Windows 10 1903 build

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you are unable to use Night Light feature after updating the computer to 1903 build. I would like to inform you that, we are aware of this issue and working on it to resolve it as soon as possible.



However, we have a workaround for this, and the workaround is to restart the PC. I would also suggest you to keep your PC updated by using Windows Update to make sure you receive all the latest updates and fixes.

1903 version night light not working

Hi Monika,

it is a known issue in 1903

Night light settings do not apply in some cases

Microsoft has identified some scenarios where night light settings may stop working, for example:

Connecting to (or disconnecting from) an external monitor, dock, or projector

Rotating the screen

Updating display drivers or making other display mode changes

Affected platforms:

Client: Windows 10, version 1903

Workaround: If you find that your night light settings have stopped working, try turning the night light on and off, or restart your computer.

Note We recommend that you do not attempt to manually update using the Update now button or the Media Creation Tool until this issue has been resolved.

Next steps: We are working on a resolution and will provide an update in an upcoming release.

Why is the Night light feature malfuctioning?

Malfunction of the night light feature is a known bug in the v.1903 feature update. See the information from Microsoft

here. Look for the paragraph that starts "Gamma ramps, color profiles, and
night light settings do not apply in some cases." No fix issued yet and considering how many bigger issues Microsoft has to deal with, my guess is that a fix for night light is lower down on the list.
