Control display settings
It’s always best to automate as many routine actions as you can and adjusting display brightness, contrast, or volume depending on your surroundings and time of day is definitely one of them. Save time and effort with DisplayBuddy — a tool made to improve your day by building in your external display controls into your Mac’s menu bar. Just one click, and you can adjust your external displays with ease!
Set your own presets
Even if it’s just a few settings, manually toggling your brightness, contrast, or volume can be daunting, especially if you regularly use the same several modes for a handful of settings, e.g. evening, office, work from home, meeting, consuming media, or playing video games. Create your own presets for different work, lighting, and viewing situations in DisplayBuddy and swiftly switch between them as needed.
Control multiple displays
If you have multiple displays attached to your Mac, you can utilize DisplayBuddy to control them. Add your compatible displays (if your display was made in the last five years, chances are it’s supported by DisplayBuddy) and enjoy ease of use and the effortless viewing experience with this helpful option.
Customize keyboard shortcuts
For people who hate to take their hands off the keyboard for small tedious tasks, a keyboard shortcut option on any tool is the best feature since sliced bread. DisplayBuddy knows it, which is why you can create your very own custom keyboard shortcuts within the app and save even more time controlling your external monitors.

This is handy for keeping the brightness of my built-in macbook display and my external Samsung monitor aligned and adjustible via the brightness keys on the keyboard. The only glitch is that whenever it wakes from sleep the external Samsung monitor’s brightness is reset and it requires tapping the brighten/dim keys on the keyboard to get it to come back into alignment with the internal display’s brightness.

A fantasic, purpose-built app if you have monitors that can support tt (most modern monitors will, I think). This app is crucial for those who want to quickly/easily control brightness/contrast across multiple monitors.
