This document serves as the user manual for the AOC LCD Monitor models U28G2XU and U28G2XU/BK. It provides comprehensive instructions for safe operation, setup, adjustment, and troubleshooting of the monitor.

Function Description

The AOC LCD Monitor is designed to display visual information from a connected computer or other video sources. It features a range of display modes and settings to optimize the viewing experience for various applications, including general use, gaming, and multimedia. The monitor supports multiple input sources, including DisplayPort (DP) and High-Definition Multimedia Interface (HDMI), allowing for versatile connectivity with different devices. It also includes USB ports for peripheral connections and an earphone jack for audio output.

Usage Features

Setup and Installation: The manual details the process of setting up the monitor, including attaching the stand and base. It emphasizes the importance of proper ventilation, recommending specific clearance around the monitor to prevent overheating. For wall mounting, it advises using a manufacturer-approved kit and following the provided instructions. Users are cautioned against placing the monitor on unstable surfaces or spilling liquids on it.

Adjusting Viewing Angle: The monitor offers adjustable viewing angles to ensure optimal comfort. Users can tilt the monitor from -5° to 23° and adjust its height by 130mm. It is crucial to hold the stand firmly and avoid touching the LCD screen directly during adjustment to prevent damage. The manual specifically warns against tilting the monitor downward by more than -5° to avoid potential screen damage, such as panel peeling, which would not be covered under warranty.

Connecting to PC: Instructions are provided for connecting the monitor to a PC using various signal cables, including DP and HDMI. Users are advised to connect the power cord securely, turn off the computer before connecting signal cables, and plug both the computer and display into a nearby outlet. The manual also includes a diagram illustrating the location of all input and output ports on the back of the monitor.

On-Screen Display (OSD) Settings: The monitor features an intuitive OSD menu for adjusting various display parameters. The OSD can be accessed and navigated using the monitor's hotkeys.
