The latest Chrome OS Dev update brings very cool features, like the new settings window. Chromebox users probably got the neatest of all improvements, though. Chromebox users can now control screen brightness straight from the keyboard’s brightness keys.

This will be a very neat feature for those who have already purchased an ASUS Chromebox. Having to adjust the brightness from the monitor settings can be a bit of a mess. The buttons are usually hidden away and the menus can be complicated to navigate. Using any keyboard’s brightness keys is much more convenient.

This feature is not available to everyone, though. There are some requirements.

How to activate Chromebox brightness control

If you meet both requirements, you can easily enable this feature and start controlling your monitor brightness from your Chromebox keyboard. Like most Chrome OS Dev features, this has to be enabled first. Here is how it’s done:

  • Open your Chrome browser.
  • Type chrome://flags/#ash-enable-brightness-control into the omnibar and press enter.
  • Enable the brightness control feature.
  • You are all set!

    Bought an HP chromebox bundle with an included keyboard. The brightness hotkeys didn’t work under stable channel. So I updated to dev channel and the brightness keys still do not work. I have dual monitors setup both from HP and both support DCC?CI connectivity. I have searched the internet far and wide for a fix. Now I am lost. Any suggestions?

    See prior comment below first.

    Also when use the chrome://flags feature no brightness setting comes up. When I try chrome://flags/#ash-enable-brightness-control I still see so no brightness setting to enable.
