    Whats the rush dude?
    First thing, people are trying to help you out. Second, if this is so inconvenient to you, just switch back to the old panel.

    Either ways im out. Hope you get this sorted.

    When putting a non-standard display in a laptop with an Nvidia gpu it is often necessary to manually enable brightness control in the Windows registry.

    The location it goes in is

    HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\...

    From the Class folder search for your GPU name, for example "980m", and you should end up in a folder called 0000, 0001, 0002, etc with a bunch of keys like EnableDpLibrary and EnableCoprocPowerControl.

    The DWORD you want to add is the following:

    EnableBrightnessControl

    After creating it set it equal to 1.

    Gotta disable javascript for this website.

    Also telling me to hurry up made me not log in from my work laptop to post this half an hour ago.

    Was the entry already present?

    You need to restart the computer after adding it. After the restart you can use the display brightness sliders in Windows. The default brightness will still be low.
