    hi all!

    I have installed 120hz AUO IPS LCD rev B156HAN04.2 in Clevo p950hp6 and by default there Is not brightness control the slider and fn buttons move and work, but with no effect.

    this might affect other Clevo and not Clevo models with 120hz+ LCDs and optimus, models such as p850hp6, p870hp6 and others.

    right now I am on a path to solution for this which is promising, but perhaps there is a known way..

    anyone? @Prema, @Meaker@Sager, @John@OBSIDIAN-PC ?

    Usually Intel HD drivers breaks it... Some drivers version work fine while others do not.
    Latest driver seems to do this (breaks it). Also some models need a bios update for it to work too.
    I'll check tomorrow for Updates on this.
