In Windows, when you use the Brightness Keys, does the brightness slider in Windows Control Panel move?


W10 will not recognize the Intel GPU, if the discrete AMD GPU is detected. The Intel GPU is suppressed by the macOS EFI firmware.

no there is no brightness slider even it's weird , there's nothing u can use to change the brightness but it was working last time before i reinstall the win , if the intel card is not detected i think i can't change the brightness !!!
