This document is a user's guide for the LG L226WU monitor, providing essential information for its safe installation, operation, and maintenance.
Function Description
The LG L226WU is a display unit designed for use with computers. Its primary function is to provide a visual interface for computer systems, supporting both analog and digital input signals. A key feature of this monitor is its USB connectivity, which allows it to function as a USB hub and supports multi-screen setups, extending or mirroring the display from a primary computer. The monitor is equipped with an On Screen Display (OSD) control system, enabling users to adjust various image parameters and settings for optimal viewing. It also includes an "f-ENGINE" feature for optimizing image conditions based on content type (movie/text) and user preferences.
Usage Features
Connecting the Display:
The monitor can be connected to a computer using DVI, D-sub, or USB cables. Users should ensure the computer and monitor are turned off before making connections. Once connected, pressing the power button will automatically execute the "Self Image Setting Function" in analog mode, which adjusts display settings for optimal input signals. For manual adjustments, the "AUTO/SET" button can be used, or the "Factory reset" option in the OSD menu.
Stand Assembly and Positioning:
The monitor comes with a stand that requires assembly. Users should place the monitor face down on a soft surface, rotate the stand body, and then assemble the stand base. Once assembled, the monitor can be carefully lifted. The stand offers ergonomic adjustments including tilt (-3° to 17°), swivel (356°), and height (maximum 5.51 inches or 140.0mm). A locking pin needs to be removed to adjust the height. It is recommended to keep the forward tilt angle within 5 degrees for ergonomic viewing.
USB Programs and Connectivity:
The L226WU supports USB connectivity, functioning as a USB hub with one upstream port and two downstream ports. The upstream port connects to the computer, while downstream ports can connect to peripherals like mice, memory sticks, or USB hard disks. For multi-screen setups, the monitor can be used to extend or mirror the display. The "LG USB Easy Connection" program, once installed, provides icons in the taskbar for easy access to features like Screen Resolution, Color Quality, Screen Rotation (Pivot function), Extend To, Extend, and Mirror. The Pivot function allows rotating the panel 90° clockwise, which requires lifting the monitor to its highest height to avoid contact with the stand base. When using multiple USB monitors, the "LG USB Easy Connection" program can be set up separately for each. The monitor supports up to five monitors in a directional connection or six in a parallel connection via USB.
Control Panel Functions:
The front panel includes several buttons for controlling the monitor:
- SOURCE Button: Selects the input signal (DVI, D-Sub, or USB).
