Screen keeps dimming on its own

Enable Adaptive Brightness is already Off. 

Turn off display after... is set to Never.

Our computers are not laptops. 

Both my wife and I have Apple CinemaDisplays and they both have recently begun to dim and brighten on their own. This doesn't occur until after logging into Windows 10. At some point—after logging in—the monitors begin to dim and brighten on their own.

When the physical brightness controls buttons (for the monitors) are used, there is something happening that fights the use of these buttons (i.e. as the brightness is increased, the levels keep going back down as the brightness is turned up. Eventually the monitor returns to it's darkest state on its own, then it will sometimesbegin to brighten again).

This issue does not occur when hooked up to our Macs, or when we were on Win7. It began with a recent Win10 update.

I have attempted to give the Nvidia Control Panel full control of the monitor, and though it can adjust the settings, it doesn't lock out whatever is causing this randomness.

    (I have no solution, but would love to have one)

    This started happening after updating my intel driver (so it is the latest).  So I'm starting to think whatever causes this gets reset whenever a driver is updated.  This is an Intel NUC Skull Canyon with integrated intel video.  This was not happening until yesterday when I updated my bios and a bunch of drivers.  I had a windows 10 system at work last year that was constantly dimming the display, even though all dimming settings on the monitor and system were disabled.  It dims while not using a bright program, as soon as I bring a bright program to the foreground (like this browser) the screen brightens.  (I would think this would be the opposite of desired behavior, that is when a white window comes forward you suddenly get blinded by the increased brightness.)

    There was a setting about setting brightness adaptively based on background image; I think that fixed my work computer.... but I can't find that setting.

    went though each adaptive brightness power setting and set it to yes and then back to no, just in case it was like totally unset and confused... still have the problem.

    I had a similar problem which turned out to be related to a Scheduled Task that is active by default. This task turns the adaptative brightness "ON" and the brightness to 50%.

    1. Search for Task Scheduler in Cortana.  Right-click the result and select Run as administrator.
    2. In the left pane in Task Scheduler, navigate to Microsoft > Windows > Display > Brightness.
    3. In the right pane, Double-click BrightnessReset to open Properties for the task.
    4. Click the Triggers tab.
    5. Select the “At log on” trigger and click the “Edit…” button to open the edit page.
    6. The Enabled radio button at the bottom of the page should be checked.  Click on the radio button to clear it.
    7. Click OK on the Edit trigger page and then click OK on the Properties page.

    Hi,

    This could have happened due to several reasons like an outdated driver to your Windows 10. We suggest that you update your drivers on your Windows 10.

    If the error still occurs, we suggest that you run the System File Checker tool and the Deployment Image Servicing and Management tool to scan and correct any issues. System File Checker (SFC) is a built-in tool in the operating system. SFC checks for system file corruption. Deployment Image Servicing and Management (DISM) is a command-line tool that can be used to service a Windows image or to prepare a Windows Preinstallation Environment image.

    Kindly follow the steps in this article posted by ZigZag3143 (MS -MVP)") to perform SFC and DISM: Run SFC and DISM.

    Let us know how it goes.

    Hi,

    Let us gather more information to properly assist you with your concern. What are the options that you have once you navigate to Microsoft > Windows > Display? Could you share with us a screenshot of the page so we can look into it?

    Looking forward to your reply.

    Regards.
