DisplayBuddy is a macOS utility that lets you control external monitor brightness, contrast, volume, inputs, and display presets from your Mac.
What is DisplayBuddy?
DisplayBuddy is a monitor control utility for macOS that helps users manage external displays directly from their Mac. It is designed for people who use one or more external monitors and want easier control over brightness, contrast, volume, input source, and other display settings without using the monitor’s physical buttons. The app supports hardware control through DDC/CI where available, and it also offers fallback methods for displays that do not fully support direct control. DisplayBuddy includes tools for syncing multiple displays, saving presets for different setups, and automating changes based on time or other events. It also integrates with macOS workflows through keyboard shortcuts, Shortcuts, Siri, widgets, and command-line automation. Published by Siddharth Gupta, it is mainly used as a Mac utility for making multi-monitor setups more convenient and consistent.

Safety overview
Status: Safe
DisplayBuddy is a legitimate display-management utility for Mac. It may need access to monitor controls, automation features, or accessibility-related shortcuts depending on how you use it, and those requests are consistent with its purpose. If you remove it, you may lose custom presets, automation, and quick control of external display settings until you reinstall it or switch to another monitor-control tool.
Recommendation: Keep DisplayBuddy if you use external monitors and rely on its brightness controls, presets, or automation. If you no longer use it, you can remove it like any other Mac app, but expect any saved display workflows and quick-access controls to stop working.
