OnScreen Control
OnScreen Control is an LG monitor companion app for macOS that manages screen layout, picture settings, and some monitor functions from your desktop.
What is OnScreen Control?
OnScreen Control is a native macOS utility for compatible LG monitors. It helps users manage screen layout with split-screen presets, adjust selected monitor settings from the computer, and access picture-related controls without using the monitor’s physical buttons for every change. LG also documents it as a tool for monitor software or firmware updates on supported models. This app is most useful for people who connect an LG external display to a MacBook, Mac mini, or other Mac and want quicker access to display organization and monitor controls during everyday work. Availability of features depends on the connected LG monitor model and connection method, so some controls may be limited on unsupported displays or non-LG monitors.
Key features
- Arrange windows with screen split layouts for multitasking.
- Adjust supported monitor settings from the Mac.
- Change picture-related options such as picture mode on compatible models.
- Detect connected LG monitors and show available control options.
- Update monitor software or firmware on supported displays.

Safety overview
Status: Safe
This is legitimate monitor-management software from LG Electronics for compatible LG displays. It may request access needed to control monitor features or manage on-screen window layouts, which is normal for this type of utility. If you do not use LG monitor-specific features such as screen splitting or software-based monitor controls, removing it mainly means losing those conveniences rather than harming macOS.
Recommendation: Keep OnScreen Control if you use an LG monitor and rely on its layout tools, picture controls, or update features. If you no longer use a compatible LG display, or you prefer changing monitor settings with the monitor’s built-in controls, you can remove it.
