Using LG OnScreen Control for Display Management
LG provides a free software tool called OnScreen Control, which makes it easier to manage your monitor’s features. While primarily used for Screen Split, application presets, and monitor settings, it also supports troubleshooting when Mirror Mode isn’t working properly.
Steps:
- Download OnScreen Control from LG’s official support page.
- Install and connect your monitor.
- Open the app and configure display options.
In some cases, OnScreen Control may display “No Monitor Connected”, which usually means:
- Wrong cables (use original LG cables if possible).
- DDC/CI not supported or turned off.
- Software-hardware communication failure.
This makes it helpful to watch a mirror instructions video specifically for the LG 34 34WR55QK-B—because video demos often include cable setup and troubleshooting.
