I'm using a late-2012 MBP with Bootcamp Windows 10 Pro (installed through BC Assistant). I'm unable to adjust screen brightness at all, either through F1/F2 (the slider shows up and animates, but doesn't do anything) or the sliders in control panel. I've googled for quite a while and haven't found any working fix yet:
- I've disabled "change brightness automatically when lighting changes"
- I've disabled "adaptive brightness" in power options
- "Night light" in screen settings for some reason does work, my screen gets tinted orange at night
- "Generic PnP monitor" in device manager is working properly
- All drivers are up to date
