3. Safety and Comfort Information

This document serves as a User Guide for an Acer LCD Monitor, providing essential information for safety, comfort, setup, and troubleshooting.

The primary function of this device is to serve as an LCD monitor, designed for video and visual display of information obtained from electronic devices. It supports various resolutions and timing standards, ensuring compatibility with a wide range of computer systems.

Usage Features:

• Display Adjustments: The monitor offers several adjustable display settings to optimize the viewing experience. Users can adjust brightness (from 0 to 100) and contrast (from 0 to 100) to achieve a comfortable visual balance between light and dark shades. A "Black Boost" feature allows adjustment of the black level (from 0 to 10) to enhance shadows without affecting lighter shades.
• Blue Light Filtering: To protect users' eyes, the monitor includes a "Blue Light" feature that filters out blue light. Users can select from 80%, 70%, 60%, or 50% blue light reduction, with 50% being the recommended setting for optimal protection as tested by TÜV Rheinland.
• Dynamic Contrast (ACM): The "ACM" (Adaptive Contrast Management) feature can be turned on or off. When set to "On," it dynamically adjusts the contrast based on the current screen content.
• Super Sharpness: This feature can be toggled on or off. Super Sharpness technology enhances image clarity by simulating higher resolution, boosting the pixel density of the original source.
• Color Settings: The monitor provides extensive color adjustment options, including Gamma mode (default 2.2), Color Temperature (Cool, Normal, Warm, Bluelight, or User-defined), and sRGB mode (on/off) for better color matching with peripheral devices. It also includes a Grayscale Mode and 6-axis Hue and Saturate adjustments for red, green, blue, yellow, magenta, and cyan.
• Audio Control: For models with audio output, users can adjust the volume and mute/unmute the sound.
• Gaming Features: The monitor includes "Over Drive" (Off, Normal, Extreme) for faster response times, "FreeSync" (on/off) for dynamically adjusting the display refresh rate to match the graphics source, and "VRB" (on/off). It can also display the current refresh rate.
• Input Selection: Users can easily switch between available input sources, such as VGA IN and HDMI1.4. An "Auto Source" feature can be enabled to automatically search for a signal source.
• Wide Mode: This setting allows users to select the screen aspect ratio, with options for "Aspect" and "Full."
• Hot Key Assignment: Customizable hotkeys (Hot Key 1 and Hot Key 2) can be assigned to various functions like Modes, Volume, Brightness, Gamma, Contrast, Blue Light, and Over Drive, providing quick access to frequently used settings.
• DDC/CI Support: The monitor supports DDC/CI (Display Data Channel/Command Interface), allowing monitor settings to be controlled via software on the connected PC.
• Quick Start Mode: This feature can be turned on or off to speed up the monitor's boot time.
• User Profiles: The monitor allows users to save custom display settings into user-defined profiles, which can be recalled later, particularly useful for different gaming modes or specific tasks.
• OSD (On-Screen Display) Menu: The OSD menu is the primary interface for adjusting monitor settings. It can be navigated using a joystick-like control on the back of the display bezel. The OSD offers options for Picture, Color, Audio, Performance, OSD, and System settings.
• OSD Language and Transparency: Users can set the OSD menu language and adjust its transparency (0%, 20%, 40%, 60%, or 80%) when in gaming mode.
• OSD Lock: This feature allows users to lock the OSD to prevent accidental changes. When locked, an "OSD Locked" message is displayed, and the LED light changes from blue to orange. It can be unlocked by pressing the "Navi Key" for more than 3 seconds.
• Power Saving: The monitor automatically enters "Power Saving" mode when no control signal is detected from the display controller, indicated by an amber power LED. It recovers quickly (around 3 seconds) when a signal is detected or the keyboard/mouse is activated.
• Ergonomic Adjustments: The monitor's screen position can be adjusted for optimal viewing comfort, including tilt (from -5° to 15°).

Maintenance Features:

• Cleaning: The monitor should always be unplugged before cleaning. A soft cloth should be used to wipe the screen and the cabinet's front and sides.
• Troubleshooting Guide: The user guide includes a troubleshooting section to help users self-diagnose common issues, such as "No picture visible," by checking LED status and suggesting remedies like adjusting brightness/contrast, checking power cords, signal cables, or computer power status.
• Product Servicing: Users are advised not to attempt to service the product themselves to avoid dangerous voltage points. All servicing should be referred to qualified service personnel, especially if the power cord is damaged, liquid has spilled into the product, or the product has been dropped.
• Environmental Responsibility: Acer is committed to environmental protection and recycling. The guide provides information on IT equipment recycling and disposal instructions, encouraging users to recycle the electronic device and providing links to Acer's sustainability website for more information on WEEE regulations.

Safety and Comfort Information:

• Accessibility: The power outlet for the monitor should be easily accessible for quick disconnection.
• Safe Listening: For models with audio, users are advised to gradually increase volume, limit high-volume listening, and turn down volume if unable to hear others speak.
• Warnings: The guide provides warnings against using the product near water, on unstable surfaces, blocking ventilation slots, pushing objects into the cabinet, spilling liquids, placing it on vibrating surfaces, or using it in environments with strong vibrations. It also specifies that the adapter is only for this monitor.
• Electrical Power Usage: Users should ensure the product is operated from the correct power type, avoid resting objects on the power cord, and ensure proper grounding of the power outlet.
• LCD Pixel Statement: The guide clarifies that minor pixel blemishes (missing or always lit pixels) are normal for LCD monitors and do not constitute a malfunction.
• Tips for Comfortable Use: The guide offers advice on preventing eyestrain and physical injury from prolonged computer use, including taking frequent breaks, maintaining good posture, and adjusting the monitor's viewing angle. It also suggests developing good work habits like regular stretching and exercise.
• Eye Care: Recommendations for eye care include resting eyes frequently, looking away from the monitor, blinking often, keeping the display clean, positioning the head correctly, adjusting brightness/contrast, and eliminating glare.
