Ihave a Samsung Ativ Book 6 NP680Z5E-X02US and recently updated to Windows 10. It uses Intel HD 4000 Graphics and has and AMD Radeon 8770M graphics card. Since updating I am no longer able to adjust screen brightness.

I have tried uninstalling the monitor and restarting. Updating all the graphics drivers. Disabling/Enabling the generic PnP monitor in device manager. Changed all of the power settings. The monitor still stays at what seems to be 100% brightness.

I recently updated W10 to anniversary edition and ran into this issue yet again. I have no idea how I was able to resolve it last time. I attempted to uninstall, and reinstall all drivers from Samsung over again, in various orders, running the Win10 Brightness Control Patch each time provided by Samsung Update, but in each case, never yielded results. I should also note that I've also disabled adaptive brightness in display options and also my power options plan. This was required the first time I got this working so I made sure those settings were changed back after the update reverted them.

There are other "control sets" other than the CurrentControlSet. I wound up changing them all to f008 prior to a reboot. Though I suspect the CurrentControlSet is all you will need.

I have a similar model NP680Z5E-X03US. Brightness control is completely unavailable using any version of either the Intel or Radeon display drivers. Neither keyboard control, system settings, display control, nor any other kind of brightness control will work.

Solved the issue. You need to install Samsung Settings VERSION 3.1To find this you will have to use samsung update and search in other models drivers and programs list. Mine Ativ 6 is XD1BR and I used the Samsung Settings softwre found in XF3BR list.

You can try [alt] + [fn] + [f4] which I found in Easy Display Manager's Option window. I didn't know what would happen but the screen cycled through various appearances and suddenly the [fn] + brightness buttons worked like a charm!
