Brightness issue when using extended screens

Discussion created by thegamer22 on Dec 9, 2019

As I can't find my problem on any other forum, I'm going to ask this here.

I'm using an RX580 with the latest radeon video driver.
I have that weird issue, that when i use my two screens in extension setup, I can't adjust brightness in games.
When I however use either one screen only or duplicate the screens, I am able to adjust the brightness.


Any suggestions about this?
Changing the "KMD_EnableBrightnessInterface2" registry entry doesn't work for me.
