    Hey guys anyone able to give me some information on this issue.

    The FN+F8 - F9 are not able to adjust my brightness on my laptop in windows 10.

    When I go into Display Settings from Desktop and move the brightness slider around this also gives NOTHING....

    I have tried disabling the Generic PnP Monitor driver which I read could help or fix the brightness issue but sadly this has not actually done anything.

    So I installed the HOTKEY software which allows me to change the brightness then I close the software reboot and then it will reboot into windows 10 with the selected brightness but I am not able to change it on the fly....

    Any ideas would be magic! Thank you all.

    Try installing GPU drivers from Intel/AMD/Nvidia to get brightness. If you've optimus i.e. Intel+nvidia GPUs first install intel and then nvidia drivers. After installing intel driver you'll get your brightness slider back.

    Actually, install the NV driver first, notebook version with Optimus support, then the Intel driver. This way the Intel driver will correctly setup both systems.

    Ok issue is fixed.

    I had to go into my power settings for the laptop and play around with the Display option in there once I did that I was able to use my FN brightness keys again on the fly. Thanks for trying to help out!

    Nice...
    You can do that? I never managed to get Nvidia driver up and running w/o installing Intel driver first.

    Same with my p170em, no matter if it was amd(7970m, 8970m) or nvidia(1060).

    That's the way it's designed in optimus/enduro systems.

    Maybe @Chastity is using hardware MUX.

    Maybe, but general advice is Intel drivers first.

    My system does have a muxer. But when I was doing support for Asus on Optimus systems w/o muxer, that doing the dGPU first allows the Intel install to detect the dGPU first time and setup accordingly.

    Then again, I'm sure drivers have improved, and if doing the Intel first works, who am I to argue? :)
