What it is

LG OnScreen Control is a desktop utility for managing features on certain LG monitors from Windows or macOS. It offers Screen Split, which divides the display into regions, and controls for brightness, contrast, and other monitor settings. My application Preset can change picture mode when you click a chosen application window, while Game mode settings let you adjust game-related monitor settings. The 5:9 Preview feature displays an application in a 5:9 area that you can move to a preferred position. The app can also update monitor firmware. A USB connection is required for settings and firmware updates; firmware updates also need internet access and a supported USB cable. Support depends on the monitor model, so LG advises checking its owner’s manual. The app does not support the PC’s Duplicate display setting; LG advises using Extend mode if its menu does not appear. A non-genuine cable or adapter can prevent DDC/CI communication, and using a third-party monitor may limit some features. The download is free for supported models.
