PRODUCT USAGE INSTRUCTIONS

Safety

National Conventions
The following subsections describe national 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 potential damage to hardware or loss of data and explains 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 regulatory authority mandates the specific presentation of the warning.

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, 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 appropriately 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 the 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 water-dampened, soft cloth.
• When cleaning, use a soft cotton or microfiber cloth. The cloth should be damp and almost dry; do not allow liquid into the case.
• 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, the 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.

Setup

Contents in the Box

• Not all signal cables will be provided for all countries and regions. Please check with the local dealer or AOC branch office for confirmation.

Troubleshoot

Problem & Question	Possible Solutions
Power LED Is Not ON	Make sure the power button is ON and the Power Cord is properly connected to a grounded power outlet and to the monitor.
No image on the screen	Is the power cord connected properly? Check the power cord connection and power supply. Is the video cable connected correctly? (Connected using the HDMI cable) Check the HDMI cable connection. (Connected using the DisplayPort cable) Check the DisplayPort cable connection. * HDMI/DisplayPort input is not available on every model. If the power is on, reboot the computer to see the initial screen (the login screen). If the initial screen (the login screen) appears, boot the computer in the applicable mode (the safe mode for Windows 7/8/10) and then change the frequency of the video card. (Refer to Setting the Optimal Resolution) If the initial screen (the login screen) does not appear, contact the Service Center or your dealer. Can you see “Input Not Supported” on the screen? You can see this message when the signal from the video card exceeds the maximum resolution and frequency that the monitor can handle properly. Adjust the maximum resolution and frequency that the monitor can handle properly. Make sure the AOC Monitor Drivers are installed.
Picture Is Fuzzy & Has a Ghosting Shadowing Problem	Adjust the Contrast and Brightness Controls. Press hot-key (AUTO) to auto-adjust. Make sure you are not using an extension cable or switch box. We recommend plugging the monitor directly into the video card output connector on the back.
Picture Bounces, Flickers, Or Wave Pattern Appears In The Picture	Move electrical devices that may cause electrical interference as far away from the monitor as possible. Use the maximum refresh rate your monitor is capable of at the resolution you are using.
Monitor Is Stuck In Active Off-Mode”	The Computer Power Switch should be in the ON position. The Computer Video Card should be snugly fitted in its slot. Make sure the monitor’s video cable is properly connected to the computer. Inspect the monitor’s video cable and make sure no pin is bent. Make sure your computer is operational by hitting the CAPS LOCK key on the keyboard while observing the CAPS LOCK LED. The LED should either turn ON or OFF after hitting the CAPS LOCK key.
Missing one of the primary colors (RED, GREEN, or BLUE)	Inspect the monitor’s video cable and make sure that no pin is damaged. Make sure the monitor’s video cable is properly connected to the computer.
The screen image is not centered or sized properly	Adjust H-Position and V-Position or press hot-key (AUTO).
The picture has color defects (white does not look white)	Adjust RGB color or select desired color temperature.
Horizontal or vertical disturbances on the screen	Use Windows 7/8/10/11 shutdown mode to adjust CLOCK and FOCUS. Press hot-key (AUTO) to auto-adjust.
