[UPDATED] Content Adaptive Brightness Control will make Windows 11 more energy-efficient
Adaptive screen brightness is a familiar function of smartphones, with both iOS and Android boosting brightness in lighter conditions to improve screen visibility, and dimming it when it is darker so you're not blinded during nocturnal social media sessions. Now Microsoft is bringing a similar -- but better -- feature to Windows 11.
Microsoft's take on the feature is called Content Adaptive Brightness Control (CABC). There is a clue in the name about how it works, and it is about more than just ambient lighting conditions. [UPDATE: Microsoft has had something of a change of heart, as detailed here.]
