    Screen auto dimming on DESKTOP


    Been having issues in the recent day with a new issue on my PC,


    im not to tech saavy, but know basics....


    My setup is as follows:


    VG248qe as main panel

    Roku tv used as second display via hdmi



    My issue is is that my second panel and ONLY my second panel dims when nothing is up and brightens when chrome is up or any app in general...ive navigated some settings, such as power...etc. and I cannot find anything that helps me stop the auto dimming feature....currently running most drivers on nvidia 1070ti (412.20 i think) and most recent 1909 install...

    :)

    Samsung Focus - Auto dimming on white background screens

    Has anyone else noticed that the screen on the Focus will dim itself when the majority of pixels on screen are white, regardless if you have auto-brightness off? For example, opening the email client or internet explorer will instantly dim
    the screen. If you set the color scheme to light/white, the home screen does not dim, but swipe over to the application list, and it dims.

    This feature is not present on the other WP7 phones, so I can only assume that Samsung added it to the OS themselves, probably as a sneaky way to artificially improve battery life (since Microsoft has strict mandates on using only three brightness
    settings).

    Is there anything Microsoft can do to remove this feature? Maybe like providing a vanilla WP7 installation? I've contacted Samsung but I couldn't even get them to understand the problem.

    How to dim screen?


    I tried googling Windows Ten, "how to dim screen," but the layout listed is not the layout I have. I just got Ten yesterday. How do you dim the screen?

    I can't even find the options in the Display section.
