    Why does brightness increase over the time?

    I like to set brightness to 50% at all times, but over the time it resets to the full strength (probably because of games), so I have to cut it by half again to 25% and then again to 14%, until it can not be lowered anymore, last time I ended somewhere around 3%.

    I tried to set it to full, uninstall GPU drivers, restart, install them again, but it never got fixed.
    It is not really a problem, I have it at 18% right now, I am just wondering, what is causing it?

    Display control centers usually mess with these settings.

    For example AMD catalyst control center or Intel HD control center run services which might reset whatever you do.
    making fixed changes there ( In control center ) could solve or at least explain what is going on.

    Also Windows updates ( on fresh Windows usually ) reset screen settings.

    I have those services disabled, but when I install new drivers, it resets it, so it makes sense. Thanks.
