OnScreen Control
OnScreen Control is LG's official monitor management utility for macOS, designed to let users adjust brightness, contrast, volume and input source on LG displays directly from the computer without using physical monitor buttons. It is particularly marketed for LG UltraFine monitors, which are designed for creative professionals including photographers, video editors and graphic designers. The app also includes features like Screen Split (for window management) and application-specific picture mode presets that automatically switch display settings when opening particular applications.
AI Recommendation
1 suggestionOnScreen Control is distributed only by LG and is not updated frequently for Apple Silicon compatibility. The search results indicate that the Mac version has persistent reliability issues on Apple Silicon Macs, including detection failures, USB-C crashes, missing features, and Rosetta 2 performance problems. Since you have until September 2028 before Rosetta 2 is removed in macOS 28, you still have time, but the current Intel-only build is unlikely to be updated natively by LG. A more practical alternative that works reliably on Apple Silicon is DisplayBuddy, which controls not only LG monitors but any DDC/CI-compatible display, adds features LG OnScreen Control lacks (keyboard brightness shortcuts, multi-monitor Presets, automatic Sync, and time-based Schedules), and requires no model-specific download. If you are committed to using LG's own software, contact LG directly to ask whether a native Apple Silicon version is planned, but based on the lack of updates and the reported issues, switching to DisplayBuddy is the more reliable path forward for Mac users.
