Build 25346: What’s new
Content Adaptive Brightness Control (CABC) on plugged in devices including desktop PCs
Content Adaptive Brightness Control(CABC) is already a feature that users are familiar with. This feature in Windows 11 will dim or brighten areas of a display or monitor based on the content being displayed with the goal of striking a balance between reduced power consumption with visual experience to save battery life. Starting with this build, we are allowing this feature to run on devices such as laptops and 2-in-1’s that are plugged into a charger. For most users, this change won’t be noticeable and should reduce energy consumption.
This feature can be adjusted via Settings > System > Display under “Brightness & color” and through a drop-down menu with 3 options: Off, Always, and “On Battery Only”. For battery powered devices such as laptops and 2-in-1’s, the default is “On Battery Only”. We encourage Insiders across laptops, 2-in1’s, to try the “Always” option and give us feedback on the visual quality of CABC so we can ensure it is properly tuned.
