The Windows Build 23424, which was recently released on the Dev channel, shows that Microsoft is expanding the “Content Adaptive Brightness Control” (CABC) feature of Windows 11 to laptops and desktops connected to chargers.
The CABC feature automatically adjusts screen brightness based on the content being displayed, and was previously only available for laptops not connected to power. This feature helps reduce power consumption and extend battery life. Microsoft stated that for laptops, adaptive brightness will be turned on automatically when using battery power. For desktops, this function is disabled by default but Microsoft encourages users to always turn it on.
