    Screen dimming on dark screen, brightens slowly on white screen


    Suddenly as of yesterday, when I open a window that is darker than a typical white Google tab a website on dark mode or similar, a website with a dark background, a game of some kind, etc. my display will dim automatically a slight bit. This seemed odd on its own, but when I flip to a different tab that has a white background or something similar, the display will slowly, in small increments, begin to brighten. It takes roughly 10 seconds each time for it to finish brightening.I do not have adaptive brightness on this computer. It is not listed in the display settings or advanced power optio

    :)

    Screen dimming and brightening on its own.

    My monitor seems to be dimming and brightening on its own. My system is a desktop with a monitor which is really a flatscreen tv.

    Everytime I close out something the screen dims. When I open up something it brightens again but it may not stay bright. When doing MS Word it will dim and brighten as I do key strokes or scrolling.

    Right now as I'm composing this thread, it is staying bright.

    I just scrolled up to the top of the screen and it dimmed (looking for post button which I now see is below and not up).

    So I have a weird screen issue where the screen brightness keeps adjusting based on how bright or dark the screen is...so when I switch from a dark screen to a brighter screen the screen seems to have dimmed and takes a few seconds to brighten to the correct
    brightness setting. Does anyone know how to fix this? Adaptive brightness is turned off.

    Screen dimming on dark screen, brightens slowly on white screen

    After upgrade to Windows 10, screen keeps dimming, then brightening!

    I have updated the Display adapters as per another answer, but the dim/brighten/dim/brighten issues seems to be persisting. Can anyone suggest another remedy please. My laptop is an HP Pavilion.
