This document serves as a comprehensive user manual for the AOC 24B3HM LCD Monitor, providing essential information on its setup, operation, and maintenance. The monitor is designed for general computing tasks, offering a clear visual display and user-friendly adjustments.
Function Description
The AOC 24B3HM is an LCD monitor primarily designed for displaying visual output from a computer or other compatible devices. Its core function is to provide a visual interface for users to interact with their digital content, whether for work, entertainment, or general browsing. The monitor supports multiple input sources, including HDMI and VGA (D-Sub 15-Pin), allowing for versatile connectivity with various systems. It incorporates Adaptive-Sync technology, which helps to synchronize the monitor's refresh rate with the graphics card's frame rate, reducing screen tearing and stuttering for a smoother visual experience, particularly in dynamic content like games. The monitor also features a "Clear Vision" function, which enhances the clarity and vividness of low-resolution and blurry images, improving the overall viewing quality.
Usage Features

It is crucial to hold the stand when adjusting the angle to prevent the monitor from toppling and to avoid touching the LCD screen directly to prevent damage.
- Wall Mounting: For users who prefer a wall-mounted setup, the monitor is compatible with VESA mounting arms (purchased separately). The manual outlines the steps for removing the base and attaching the mounting arm, emphasizing the importance of following the manufacturer's instructions and ensuring proper cable reconnection.
