Microsoft testing adaptive brightness on more Windows 11 devices

Microsoft says a new Windows 11 preview build rolling out today will allow Insiders to test the company’s adaptive brightness feature on more systems.

While Content Adaptive Brightness Control () could previously only be used on laptops while running on battery, CABC can now also be toggled on plugged-in devices (including desktop PCs).

“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,” Microsoft’s Amanda Langowski and Brandon LeBlanc .

“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, as well as on desktop PCs.”

While Redmond says enabling this setting will be unnoticeable for most users and help reduce energy consumption, the sudden brightness and contrast changes may prove distracting for users who require color accuracy.

To deal with this, Windows Insiders can configure the CABC feature using a drop-down menu under “Brightness & color” by going to Settings > System > Display.

While the available options are Off, Always, and On Battery Only, Microsoft is asking testers to toggle on the always-on option on their laptops, 2-in1’s, and desktop PCs and provide feedback on the visual quality so CABC can be adjusted before landing in stable releases.

Microsoft is also asking Insiders in the Dev Channel running the new Windows 11 Insider Preview Build 23424 to test a Windows Update option dubbed “Get the latest updates as soon as they are available” that will fast-track non-security updates to systems where it’s toggled on.

“This new toggle is meant to be used in the Beta Channel to allow Insiders to switch more seamlessly to the enablement package. But because the Dev Channel does not use an enablement package, turning this toggle on will not do anything for Insiders in the Dev Channel,” Langowski and LeBlanc said.

“However, by turning it on, a ‘Windows configuration update’ will be offered via Windows Update that is designed to help us make sure it this new toggle is connected to our backend services correctly before making it available in the Beta Channel.”

Today, Microsoft also began  to Insiders in the Canary channel, which comes with several Microsoft Store improvements, including the option to install free apps and games directly from search results, a redesigned purchasing experience, and new UX for in-app ratings.
