    Changing brightness is no longer smooth with function keys on 1903


    I was forced to update to Win10 1903 today from 1809 by Windows and after updating I encountered a bit of an issue,

    changing the brightness now isn't as smooth as it was before with the function keys as seen here [youtube]SEyRYGojBsA[/youtube]

    in comparison,

    changing the brightness with the function keys used to look something like this [youtube]GZoZ486Rrtk[/youtube]

    I don't know if it's an installation issue or if Microsoft changed the behavior of how the brightness works but

    I'm hoping to see if there's a fix for this because it's really annoying me for a number of reasons

    :)

  2. Function key will not work correctly when setting up brightness.

    Hi Ashique,

    Sorry for the delay in response.

    • What is the make and model of the computer?
    • Do you face the issue with only brightness?

    The special keys like Fn key with the options to change brightness or to reduce sound are provided by the laptop manufacturer.

    We would suggest you to update or download the software from the computer manufacturer website.

    After the latest Windows Update, brightness control and custom keyboard shortcuts no longer function

    Acer 1810TZ

    64 bit OS and processor (4GB)

    Windows 10 Pro

    Version 1803

    Build 17134.48

    Installed 05/17/2018

    Quality Updates Installed

    • KB4103729
    • KB4103721
    Definition Updates Installed

    • KB2267602

    Like the subject says, I've lost brightness control as well as custom keyboard shortcuts I had setup to start programs (Ctrl + Alt + [letter]). I just discovered the latter not working. Brightness control no longer works with function key shortcut, icon
    in the notification panel, or adjusting the brightness slider in Settings.

    Note that Windows key shortcuts DO work. Volume control DOES work with function key, system tray icon slider, etc.

    I've tried the following to no avail:

    • updating display and monitor drivers as well as switching to the basic Microsoft display.
    • uninstalling update
    • reinstalling the update
    • the old voodoo trick of rebooting at each of the above steps

    I'm at a loss as to what to try or what to even what to search for at this point. Thanks for your help!

    Changing brightness with Fn key costs delay

    This is a change in steps from 0 to 10 which is almost smooth to the human eye. All Acer laptops work like this and have been for several years.
