    Nightlight only working on one of three monitors


    Hello,I have tried to switch from f.lux to Windows nightlight, as f.lux causes some issues for me. However when I turn on Windows Nightlight, it only affects one monitor. The monitor it works on is plugged in via DVI, the others are HDMI and DP.I already tried deleting the nightlight registry entries as suggested in other question, and restarting my device. My AMD Drivers are up to date as well. f.lux is turned off not just temporarily disabled, but completely closed.Any assistance would be welcome,Thank you

    :)

    nightlight

    I deleted the two registry entries suggested here, but the nightlight setting is still grayed out, https://answers.microsoft.com/en-us...-ff12-469a-907e-a2b61e9434e7?tm=1577644628359

    If I create a new account this setting works fine . I could delete the malfunctioning account but short of copying the registry from one account to another, I don't know how to move the files and few setting and make a few programs available in the new.
    If I copy and move the registry then the defect follows.

    Any suggestions please.

    nightlight

    Thank you for the answer. I am rather weary of replacing the OS to correct the nightlight problem. I can just start using another account, a less drastic solution. The SSD is not easily swapped so I would have to erase the current drive or install
    over, a sometimes problematic step. Thanks.
