Where Does LG OnScreen Control Store Profiles?
OnScreen Control keeps monitor layouts, app presets, and firmware state per display. Screen Split profiles save window arrangements instantly.
Last updated
OnScreen Control tunes LG monitors from the desktop. Screen Split layouts with app presets, picture modes, dual-controller KVM settings, and firmware state live in local app data per display. Hardware keeps the running config.
That makes the app the editor with exports as backup number two. Exact folder names may vary by version. USB upstream cables carry control data; video cables alone configure nothing. Picture modes calibrate per input. Dual-controller shares peripherals. Firmware notes list fixes.

Frequently asked questions
How do I back up Screen Split profiles?
Open OnScreen Control with the monitor connected over USB upstream and export profiles where offered. Layouts reference app executables by path. Reinstalls need displays reconnected per machine.
How do I update monitor firmware?
Open the app and check for firmware prompts per connected monitor. Keep USB upstream plugged until each finishes. Update one display at a time on multi-monitor desks.
