Cannot control external monitor brightness on Mac mini using Satechi Bluetooth keyboard

Controlling brightness with keyboard

I have a Mini 5Pro and a Satechi bluetooth backlit keyboard, I am trying to control the brightness of my main monitor with the keyboard and can not find a way, the monitor is the main one of the three, used for FCP and as all monitors, a headache to controlling it manually.

Sorry to be the bearer of bad news, but the Mac mini's have never allowed brightness control using after-market external displays or after-market input devices.


You must use the displays on-board menu or find some type of third-party brightness control software that does not mess with your color profile or FCP work.

macOS does not natively support direct software or keyboard brightness control for most third-party external monitors connected to a Mac mini.

How to Adjust Brightness on a Mac Mini

  • Use the Monitor's Physical Controls: The standard way to change brightness on an external display connected to a Mac Mini is by using the physical buttons or the on-screen display (OSD) menu built into the monitor itself. [1]
  • Install Third-Party Control Software: To adjust brightness using your keyboard or menu bar like a built-in Mac display, you can use free or paid third-party utilities:
    • MonitorControl: A popular, free, open-source app that lets you control external monitor brightness and volume using standard keyboard keys or the menu bar via the DDC/CI protocol.
    • Lunar: A feature-rich app offering hardware and software dimming, with a free manual mode and paid adaptive features.
    • Software-Only Dimming Apps: Apps like QuickShade or Mac App Store screen filter tools apply an overlay or gamma adjustment if your monitor doesn't support hardware DDC control. [1, 2, 3, 4]

Thanks for the responses, never could do it with my previous MX keys either, lately I thought: how would the system understand that I want to modify the main monitor only and not the other two? So I have to stick to the painful manual process on the monitor. BTW, never liked the Mac keyboard or mouse, my MX keys died after 3-4 years, so I switched to Satechi, and there is nothing as good as the MX Master mouse. This should be the end of my query.

What did the manufacturer of the monitor say when you reported the issue to them?


Can you control the brightness of that monitor using any keyboard connected to your Mini?

You're welcome. I hear you, we mostly use Logitech MK-120 USB combo's with our Mac mini's.
