GTX 970M installed + Windows 10. Screen Brightness Control not working

Recommended Posts

Just upgraded from 7970m to 970m. Running a modded inf (latest driver) and I can't get it to work. Tried going into regedit to change the value from 1 to 0 (it worked on the 7970m before...) and still no change.

Any thoughts? I can try older drivers I suppose, but chime in if you're using windows 10 on m15x with 970m and can change the brightness setting.

I found the fix. I had to go into the GPU side of regedit and add "RMBrightnessControlFlags" then set it to 800.
