If you want to make things even easier, the app lets you use the brightness keys on Apple’s Magic Keyboard (or any other key combination you like) to adjust brightness and volume. In some cases, you can also adjust the contrast and volume of an external display directly from DisplayBuddy. The app relies on the DDC-CI protocol to work. Then, just click the DisplayBuddy icon in the macOS menu bar to adjust the brightness of external displays connected to your Mac. In fact, all you need to do is install the app and open it. Setting it up for the first time is super easy. The good news is that DisplayBuddy works not only with Intel Macs, but also with Apple Silicon Macs. In fact, I used a similar tool in the past with my 2017 MacBook Pro, but it was never updated with support for M1 Macs. Luckily, DisplayBuddy makes the brightness controls work in macOS as if I were using an Apple display.ĭisplayBuddy is not the first app in this category. As you can imagine, this is quite annoying and far from elegant and intuitive. As a result, the only way I have to increase or decrease its brightness is by using the monitor’s built-in buttons. Personally, I have a 4K monitor from LG that has no macOS integration. The tool is extremely useful for those who have a third-party display. This means that you no longer need to access your monitor’s settings to adjust the brightness. With DisplayBuddy, users can control the brightness of external displays directly from their Mac. However, most third-party displays don’t have macOS integration – but this is something you can fix with DisplayBuddy. When you use your Mac connected to an Apple display or an LG UltraFine (which is officially supported by Apple), changing the brightness of the external display is just as easy as doing it on your Mac’s display.
