DisplayBuddy

DisplayBuddy lets users adjust brightness, contrast, volume, and input source of external monitors directly from their computer. It communicates with displays via DDC, supporting a wide range of brands such as Dell, LG, Samsung, and Xiaomi. The interface is integrated into the macOS menu bar and also works on Windows, providing sliders and shortcuts for quick changes without using hardware buttons.

The application offers preset management, allowing users to save and restore groups of settings for different scenarios like work, movies, or gaming. Presets can be applied across multiple monitors with a single action, and keyboard shortcuts enable rapid adjustments. Compatibility includes Apple Silicon Macs and multiple displays on a single system.

DisplayBuddy focuses on providing fine‑grained control over external screens, handling real‑time brightness and contrast changes and supporting input source selection. It is positioned as a stable utility for users who need consistent, software‑based monitor management across major display manufacturers.
