Safety

National Conventions

The following subsections describe the notational conventions used in this document.

Notes, Cautions, and Warnings
Throughout this guide, blocks of text may be accompanied by an icon and printed in bold type or in italic type. These blocks are notes, cautions, and warnings, and they are used as follows:

NOTE
A NOTE indicates important information that helps you make better use of your computer system.

CAUTION
A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem.

WARNING
A WARNING indicates the potential for bodily harm and tells you how to avoid the problem. Some warnings may appear in alternate formats and may be unaccompanied by an icon. In such cases, the specific presentation of the warning is mandated by regulatory authority.

Power

The monitor should be operated only from the type of power source indicated on the label. If you are not sure of the type of power supplied to your home, consult your dealer or local power company.

• The monitor is equipped with a three-pronged grounded plug, and a plug with a third (grounding) pin. This plug will fit only into a grounded power outlet as a safety feature. If your outlet does not accommodate the three-wire plug, have an electrician install the correct outlet, or use an adapter to ground the appliance safely. Do not defeat the safety purpose of the grounded plug.
• Unplug the unit during a lightning storm or when it will not be used for long periods of time. This will protect the monitor from damage due to power surges.
• Do not overload power strips and extension cords. Overloading can result in fire or electric shock.
• To ensure satisfactory operation, use the monitor only with UL-listed computers that have appropriate configured receptacles marked between 100-240V AC, Min. 5A.
• The wall socket shall be installed near the equipment and shall be easily accessible.

Installation

• Do not place the monitor on an unstable cart, stand, tripod, bracket, or table. If the monitor falls, it can injure a person and cause serious damage to this product. Use only a cart, stand, tripod, bracket, or table recommended by the manufacturer or sold with this product. Follow the manufacturer’s instructions when installing the product and use mounting accessories recommended by the manufacturer. A product and cart combination should be moved with care.

• Never push any object into the slot on the monitor cabinet. It could damage circuit parts causing a fire or electric
  shock. Never spill liquids on the monitor.

• Do not place the front of the product on the floor.

• If you mount the monitor on a wall or shelf, use a mounting kit approved by the manufacturer and follow the kit instructions.

• Leave some space around the monitor as shown below. Otherwise, air circulation may be inadequate hence overheating may cause a fire or damage to the monitor.

• To avoid potential damage, for example the panel peeling from the bezel, ensure that the monitor does not tilt downward by more than -5 degrees. If the -5 degree downward tilt angle maximum is exceeded, the monitor damage will not be covered under warranty.

See below the recommended ventilation areas around the monitor when the monitor is installed on the wall or on the stand:

Cleaning

• Clean the cabinet regularly with a cloth. You can use soft detergent to wipe out the stain, instead of strong detergent which will cauterize the product cabinet.
• When cleaning, make sure no detergent is leaked into the product. The cleaning cloth should not be too rough as it will scratch the screen surface.
• Please disconnect the power cord before cleaning the product.

Other

• If the product is emitting a strange smell, sound, or smoke, disconnect the power plug IMMEDIATELY and contact a Service Center.
• Make sure that the ventilating openings are not blocked by a table or curtain.
• Do not engage the LCD monitor in severe vibration or high-impact conditions during operation.
• Do not knock or drop the monitor during operation or transportation.
• The power cords shall be safety approved. For Germany, it shall be H03VV-F, 3G, 0.75 mm2, or better. For other countries, suitable types shall be used accordingly.
• Excessive sound pressure from earphones and headphones can cause hearing loss. Adjustment of the equalizer to maximum increases the earphones and headphones output voltage and therefore the sound pressure level.

Frequently Asked Questions

Is AOC monitor good or not?

Yes, AOC is a good brand for monitors. It offers various monitors with HD resolution, exceptional picture quality, and wide viewing angles.

Is AOC better than Dell?

The AOC has a higher 1440p resolution compared to the Dell's 1080p, making it a better choice if you also use it for work, but its response time isn't as good as the Dell's, especially in dark scenes.

What is a 4K monitor?

A 4K monitor, also known as an Ultra HD (UHD) monitor, has a resolution of 3840x2160 pixels, providing a significantly higher level of detail and sharpness compared to standard Full HD monitors.

What are the benefits of using a 4K monitor?

The main benefits of a 4K monitor include enhanced image clarity, sharper text, and the ability to display more content on the screen. It's particularly beneficial for tasks like photo editing, video editing, gaming, and watching high-resolution content.

What is the ideal size for a 4K monitor?

The ideal size for a 4K monitor depends on your personal preference and the distance at which you'll be viewing the screen. Generally, larger sizes like 27 inches or above are recommended to fully appreciate the increased resolution.

Do I need a powerful computer to use a 4K monitor?

To fully utilize the benefits of a 4K monitor, it's recommended to have a relatively powerful computer with a capable graphics card. This ensures smooth performance and the ability to handle the increased resolution.

Can my operating system and software support a 4K monitor?

Most modern operating systems, such as Windows 10, macOS, and Linux, support 4K resolutions. However, it's important to check if your specific software applications also support high resolutions to ensure optimal compatibility.

What connectivity options are available for 4K monitors?

Common connectivity options for 4K monitors include HDMI, DisplayPort, and USB-C. Ensure that your computer's graphics card and monitor have compatible ports to achieve the desired resolution and refresh rate.

What is the refresh rate of a 4K monitor?

The refresh rate of a 4K monitor can vary. Some models offer a standard 60Hz refresh rate, while higher-end models may provide a 120Hz or 144Hz refresh rate. Higher refresh rates are beneficial for gaming and smooth motion- intensive activities.

Are there any specific settings I need to adjust for a 4K monitor?

To make the most of your 4K monitor, you may need to adjust the scaling settings on your operating system to ensure text and icons are appropriately sized. Additionally, calibrating the monitor's color settings can enhance image quality.
