Product: HP ZBook Power 15.6 inch G9 Mobile Workstation PC (4T506AV)

The ZBook G9 should actually be able to set it's display brightness adapted to the environmental brightness. Doesn't it have a brightness sensor? How to use it?

Hi @msssm 

 

 it depends on the screen, these models can have up to 5 different screens, to know if your screen is compatible you should enter in :Windows SETTINGS > BRIGHTNESS  and COLOR
