  1. Cannot Change Brightness

    My device was on hold for the 1903 Update, recently the update arrived but since updating I am unable to change the brightness and brightness slider is also missing. Night Light also does not work and toggling the night light option does not activate it.

    Windows 10 Pro
    Version- 1903
    Installed on- August 3, 2019
    Build- 18362.267

    The below screenshot shows the missing Brightness Option

  3. screen brightness on windows 10


    Some computers can let Windows automatically adjust screen brightness based on the current lighting conditions.

    To manually adjust the screen brightness, we suggest following these troubleshooting steps:

    • Click Start, then select Settings.
    • Choose System, then select Display.
    • Under Brightness and color, move the Change brightness slider to adjust the brightness.

    Feel free to post back if you have other concern.
