    Brightness Goes Up to 100 Randomly


    Hi, all.

    On my new Lenovo Legion 7 running latest version of Windows 10x64 PRO I'm facing an weird issue.
    Occasionally, and mostly after the screen goes off, but not only then, it could also happen when browsing some pages, the brightness goes up to 100%, which is not very comfortable for eyes (~500 nits).
    I disabled Intel's Display Power Saving utility, Lenovo Legion 7 does not seem to have adaptive brightness option, I have the latest drivers downloaded from Lenovo's dedicated page for this laptop model, both for integrated GPU (which controls the display) and for the dedicated GPU. Also, X Rite Color calibration software (which I presume is useful mostly for video/photo editors) is now set *not* to start with Windows, and in the Display settings section of Control Panel I selected the default Display profile called "Lenovo Legion 1920*1080". This laptop is mostly used for coding, and as you would expect, 500+ nits is not pleasant at all.

    Could you please advise what should I do to get rid of this utterly annoying issue?

    Thank you in advance.

    :)

    Brightness Control not working in Windows 10

    Hi Ella,

    To adjust the brightness, see the steps below:

    • Go back to Power Options, and tick on the High performance.
    • See if you can adjust the brightness.

    If this not work, we highly suggest that you create an Administrator account, and re-do the steps above.

    Let us know how it goes.

  3. Brightness randomly goes up and back down

    Hello!

    Since last weeks, my laptop has this weird issue:
    It's brightness goes up for a brief second, then goes back to normal settings.
    I don't think it's hardware because none of my laptop's wires get touched.

    How can i find out if and which application changes my screen brightness programatically?

    Thanks,
    Alex

    screen brightness on windows 10

    Hi,

    Some computers can let Windows automatically adjust screen brightness based on the current lighting conditions.

    To manually adjust the screen brightness, we suggest following these troubleshooting steps:

    • Click Start, then select Settings.
    • Choose System, then select Display.
    • Under Brightness and color, move the Change brightness slider to adjust the brightness.

    Feel free to post back if you have other concern.
