    How to reduce laptop brightness below minimum?


    I have Dell XPS 17 laptop with Windows 10 Home 21H2

    My screen brightness on minimum setting is still too bright.

    How can I reduce brightness below the minimum?

    Thanks

    You cannot unless you turn it off.

    Change Gamma.

    Download Gamma Panel - MajorGeeks

    Then if you want to get more advanced use:

    Download CPKeeper - MajorGeeks

    You can grab gamma ramp set in GammaPanel and set it to be applied on boot va CPkeeper.

    Otherwise it's a question of using whatever graphics control panel is installed.

    In your Display settings. Like Nvidia Control panel or Catalyst Control Center.
    Set the brightness on the screen as low as you can, then use the vid card brightness settings to go lower.

    I have a DELL monitor and even with the brightness set to zero, it was still far too bright.
    So... enter Nvidia Control Panel...

    Ditto on the above but if you can't adjust that way then I forgot to mention:

    Save current profile as default and then save the new profile to run on boot. It's easy to create multiple profiles and switch at will.

    Earlier this evening, I saw similar advice on a different site. The author had the same graphics card as I have.

    I wrote the following line in my journal:

    - Intel R UHD graphics

    Unfortunately, IMO both the site author and yourself have omitted an essential step.

    You both show a screenshot of the panel, but AFAIK, you don't say how to open the panel

    But thanks anyway.

    I've never had Intel graphics.

    For Nvidia, you just right click the desktop and choose: Nvidia Control Panel.

    OldGrantonian,

    Intel have been removing the graphics control panel as they have been updating drivers.
    Unless you have a link to it in your Start menu or by right-click in the desktop then you can assume you don't have one.

    You should check in your Bios for any further ability to adjust brightness levels.

    What is a Grantonian anyway?


    All the best,
    Denis

    You can work it out by looking at my avatar, and comparing with "Old Etonian", "Old Harrovian", and so on - although I'm not as grand as them

    I have Dell XPS 17 in Win 10 Home 21H2

    I'm attaching 2 screenshots to show the differences between Edge and Google browsers using Gamma Panel.

    I tried to ensure that the screenshots were to the same scale. My method was to ensure that they were the same size, and enclosed the same items at corners and edges. (Tip: Ctrl+, and Ctrl- give a much finer adjustment than the sliders)

    Settings were as follows;

    Dell brightness setting:
    - Minimum

    Gamma Panel:

    - Gamma 0.68
    - Brightness -16% (That shows how bright my Dell was on minimum brightness)
    - Contrast 0.91

    Edge:

    Google:

    You can see that - in this post - the Edge image (from Greenshot) looks larger than the Google image.

    But the same images within the Greenshot editor fit almost exactly on top of each other.

    Here are the image file sizes:

    .
    So the visually smaller Google file is more than double the KB of the Edge file. That might imply greater granularity. But beware: both maps contain advertising info as well as geographical info - so that might affect file size.

    As an interesting footnote, I'm typing this post in Google - which presumably will now be my browser of choice. I'm using Print Preview, so I know what the images look like in Google. But I'm not bright enough to know how to view this unposted post in Edge. I've been around long enough not to trust anything

    Thanks.

    Added in a Google browser after viewing this post in Edge. (Now I'm getting confused.)

    Anyway, this post looks terrible in Edge. The two screenshots are almost identical. Google is still better - but only just.
