Use the on-screen menu or the LG Switch application to arrange windows, adjust color and HDR settings, and map hotkeys for quick actions.

Recommendations

For best HDR and color performance, use a source device that supports HDR output and enable HDR in both the source and the monitor. Keep firmware and the LG Switch app updated. For extended comfort during long sessions, set the monitor height so the top third of the screen is at eye level and take regular breaks.
