When I plug my Mac into a DisplayPort or HMDI monitor that has built-in speakers, Mac’s volume controls become disabled. Not being able to control my monitor’s sound has annoyed me for years, but I’ve never looked for a solution. When upgrading to the new MacBook Pro M1, I hoped Apple would have fixed the issue. Unfortunately, the problem still happened, so I when searching for a solution.
I came across several articles that were outdated and recommended Soundflower. I kept searching for a better solution and came across MonitorControl. After a quick install, I found MonitorControl to be a great solution to my problem. MonitorControl has tons of options, such as controlling the brightness of your monitor and keyboard shortcuts. I can now control the volume and mute from my Logitech MX mouse.
How To Install
If you use Homebrew, just run:
brew install --cask monitorcontrol
Or install the latest version from the GitHub Repo
MonitorControl is a neat tool that makes it easy to adjust brightness and volume. pic.twitter.com/TsOEejLf6P
