This document serves as the owner's manual for the LG IPS LED Monitor, models 22MP55D, 22MP55A, 23MP55D, 23MP55A, and 24MP55D. It provides comprehensive instructions for assembling, operating, customizing, and troubleshooting the monitor, ensuring users can maximize its features and maintain its longevity.
Function Description
The LG IPS LED Monitor is designed to provide a high-quality visual experience for various applications, including general computing, text-based tasks, photo viewing, video playback, and gaming. As an IPS (In-Plane Switching) LED monitor, it offers superior color accuracy and wider viewing angles compared to traditional TN (Twisted Nematic) panels, making it suitable for tasks requiring consistent image quality. The LED backlighting contributes to energy efficiency and a slim design.
The monitor supports both analog (D-SUB) and digital (DVI-D) input signals, allowing connectivity with a wide range of personal computers. It is a Plug & Play device, meaning that when connected to a PC and powered on, the computer automatically recognizes the monitor without requiring complex configuration. This simplifies the initial setup process for users.
A key feature of this monitor is its "Self Image Setting" function, which automatically adjusts display settings to optimal levels when the monitor is first connected to a PC, particularly in Analog Mode. This ensures a good out-of-the-box experience. Additionally, an "AUTO" function is available to improve resolution and address issues like blurry screens, blurred letters, screen flicker, or tilted screens, especially after changing screen resolution or using the device.
The monitor also incorporates several advanced display modes and settings to enhance user comfort and productivity. These include "Reader Mode" for a paper-like viewing experience, "SUPER ENERGY SAVING" for reduced power consumption, "Picture Mode" with presets for different content types (Custom, Text, Photo, Cinema, Game), and "SUPER RESOLUTION+" for optimizing image quality. Furthermore, "DUAL DISPLAY" and "DUAL WEB" functions are available to improve multitasking and web browsing efficiency, although these require the installation of the DUAL SMART SOLUTION program.
Usage Features
The monitor's user interface is designed for intuitive navigation through its On-Screen Display (OSD) menu, accessible via buttons located on the bottom switch panel.
Assembly and Setup:
- Unpacking: The manual details the items included in the product box, such as the CD (Owner's Manual/Card), D-SUB Cable (optional), DVI-D Cable (optional for certain models), Power Cord, AC-DC Adapter, Stand Body, and Stand Base. Users are advised to check for missing accessories and contact their dealer if necessary.

The AC-DC Adapter and Power Cord are then connected to a wall outlet, and the monitor is powered on using the bottom switch panel button.
- Mounting on a Wall: For wall mounting, users are instructed to attach a VESA-compatible wall mounting interface (optional parts) to the back of the set. Specific VESA standards, screw dimensions, and clearances (10 cm on each side and from the wall) are provided to ensure proper ventilation and secure installation. Warnings are given against overtightening screws, using unauthorized mounts, or installing on slanted walls, as these can cause damage or injury.
