    Night light not working


    When I turn Night Light on nothing happens.

    The color of the screen does not change.


    What I tried:

    Updating my GPU drivers:

    I'm using two monitors.

    each monitor has it's own GPU.

    I updated the drivers of both to the latest.

    Turning strength up:

    Night Light is on maximum strength still nothing.

    recalibrating my monitors:

    Windows Settings->Display->Advanced display settings->Display adapter properties for Display->Color Management->Color Management...->Advanced->Display Calibration->Calibarite display


    Night Light does turn on automatically.


    Night Light used to work and stopped working when I updated to a Windows Insider build. Now I'm not on an insider build.


    Monitor primary:

    1920x1080

    60 Hz

    8-bit

    RGB

    SDR

    color calibrated using windows 10.

    connected to NVIDIA GeForce GTX 1050 Ti latest drivers

    Monitor secondary:

    1920x1080

    60 Hz

    8-bit

    RGB

    SDR

    color calibrated using windows 10.


    connected to Intel HD Graphics 4600 latest drivers


    Windows:

    Windows 10 Pro x64

    Build 1903

    OS Build 18362.175


    I have waited for a software update to fix this for a while. no windows update helped. Upgraded to Windows 10 Pro didn't help.


    Night Light used to work on both monitors and stopped working on both monitors.

  2. No Night Light

    Hi allisonb1

    Try these steps

    Option 1. Reset Night Light-related Settings on Windows 10 Fall Creators Update

    If you find the night light in the Action Center or the Settings is greyed out after the Windows 10 Fall Creators Update, you can fix it with the steps below:

    Step 1. Use Windows shortcut keys Win + i to open Settings.

    Step 2. Go to the Privacy menu.

    Step 3. On the left side, choose the Location tab.

    Step 4. Click the Change button under the Location for this device.

    Step 5. Toggle the switch under the Location for this device to ON.

    Step 6. Toggle the switch under the Location service to ON.

    Step 7. Restart the computer.

    Now check the Action Center or the Settings on your Windows 10 Fall Creators Update to see if the night light feature is available.

    Option 2 . Modify Registry to Fix Night Light Not Working on Windows 10 Fall Creators Update

    If the methods above didn't work, you may need to modify the registry to fix the greyed-out night light button or the night light not working issue. Note: Windows Registry is a vital database on Windows OS computer. Any misoperation will cause server system
    problems, such as 100% disk usage issue, blue screen issue, endless reboot, etc. So it's important to backup registry before the changes.

    Now let's kill the night light not working and release the pain:

    Step 1. Use Windows shortcut keys Win + R to launch Run.

    Step 2. Type into regedit.

    Step 3. Hit the Enter key.

    Step 4. Copy and paste the path into the address bar of the Registry Editor: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount

    Step 5. Press the Enter key.

    Step 6. Right-click the key $$windows.data.bluelightreduction.bluelightreductionstate under the DefaultAccount and select the Delete to remove it.

    Step 7. Right-click the key $$windows.data.bluelightreduction.settings and select the Delete.

    Step 8. Restart the computer.

    Then you can go to the Action Center or the Windows Settings. The night light not working issue has been resolved now and the night light button is available.

  3. Night Light Setting and Third Monitor.

    Hi Reagan,

    We would like to ask you some questions in order assist you properly:

    • Did Night light work previously on all three monitors?
    • Have you made any recent changes to your PC?
    • Are you getting an error message on the third monitor regarding Night light?
    • Is the third monitor being detected by your PC?
    • What troubleshooting steps have you performed so far?

    While waiting for your response, we suggest that you try to connect your third monitor to what you are using on the 2 working monitors to see if it is only a loose connection issue.

    Regards.
