Display Brightness

Brighter or dimmer on the display you’re working on, external monitors included.

Dim the second monitor a notch in the evening.

The brightness keys on a Mac only reach the built-in screen and Apple displays. Other monitors you’d set with their own buttons. ⌃⌥⌘K and ⌃⌥⌘O do both.

External monitors are controlled over the cable (DDC/CI). That works over USB-C, Thunderbolt and DisplayPort, but not through the HDMI port of many Macs or some docks. Then the pop-up tells you which monitor teespoons couldn’t reach.

  • One press is one sixteenth, like the Mac’s own keys
  • Needs no permission

The app has a short tutorial for this. In the settings window, click Try it on the spoon’s page or press Command 5 for Tutorials.
