    Is there a way to adjust the brightness setting through regedit or something?

    can u just adjust the monitors brightness, or are you looking for an auto adjust program that adjusts the brightness for the time of day or night. a good program for that is f.lux :(

    Nope can't adjust monitors brightness as it's a Laptop LCD :( I usually turn down the brightness when it's late so it's less bright on my eyes even tho I use f.lux as-well.

    you should have some Fn keys on your keyboard which allow adjusting some parameters like monitor brightness etc

    Normally all Laptops having an Fn-Key for to adjust the backlight (brightness) of it's LCD/LED Screen!! Maybe you should consult the Manual of your Laptop or the Website of the manufacturer by looking up for your model?!

    To change the display brightness on a laptop


    1. Open Power Options by clicking the Start button Picture of the Start button, clicking Control Panel, clicking System and Security, and then clicking Power Options.


    2.Move the slider next to Screen brightness at the bottom of the screen. The brightness changes automatically

    can you make these adjustment's on your laptop o_O

    Yes there are.

    However it heavily depends on your specs.

    Do you have Intel + Nvidia, Intel + AMD, AMD + AMD, Intel ?

    "Never ending story without the white flying dog"

    I need your specs please.

    The dword that is responsible for brightness control is FeatureTestControl on the Intel drivers.

    We have a tool over on leshcatlabs.net called UBR/ UniversalBrightnessResolver which allows you to change your FTC value.

    If you give me your exact specs and the AMD / Intel driver you are using I will be able to help you more.

    I will take a look at your HP driver to see if it has an FTC value that might potentially work.

    Which Intel HD 4000 drivers have you tried to install?

    15.33.29.64.3945 ?

    I assume you tried 14.9 / .1 AMD ?


    Edit:

    Would you please be so kind to provide the DevID for your Intel card (found in the device manager)

    15.33.29.64.3945 = Intel
    (Latest)

    AMD 14.9

    What do you mean by DevID?

    The DevID is what identifies your Device. So in short the HP drivers use your specific Intel DevID during install to allocate the proper FeatureTestControl dword to the driver.

    I have just had a look and it seems to be F840 (your original driver sp59678 - for Windows 8)

    However: The FTC value which might have worked for the older HP Intel driver might not work for the new 3945 driver, meaning that it requires a little trial and error.


    For example the official 3945 driver allocates you with FTC value F000. This value is like an on off switch for several Intel technologies/features including brightness control, standby, lowering Hz during idle etc.

    What you want to do is to use the UBR tool (which changes the FTC value in your device via a GUI) to apply a new FTC value. Each time you change the value a restart is required to take effect (was on windows 7). On Windows 8.1 and I assume 10 all you will need to do is disable Intel via Device Manager and enable it to see if the changes made a difference.

    The values you want to try are:

    F840
    F842
    F940
    F942

    Scroll down for the tool and let us know how it goes!

    For example:

    This is my Envy 17 2xxx, Intel HD 3000, 6850m. Running Windows 8.1, Intel 3517 and AMD 14.9.1:

    example.JPG

    My IntelKMD value is blank (I suggest you leave it blank too)

    Fill in a custom value via [J] so that it reads:

    "CurrentControlSet Intel (0001): 0xf800"
    "ControlSet001 Intel (0001): 0xf800"

    "ControlSet Intelkmd: "
    "ControlSet001 Intelkmd: "

    you will also want to try F800 and F900 incase the other values do not work.

    Which values have you tried? All of them set just like in the picture?

    Also does Intel HD 4000 installed by itself have working brightness control?

    I don't need to restart right in windows 10 just disable and re-enable intel hd?
    I can change the brightness through the IntelĀ® HD Graphics Control Panel.
