AOC 27B30H LCD Monitor User Manual

Safety
Ensure the monitor is operated only from the specified power source indicated on the label. If unsure, consult your dealer or local power company. Unplug during lightning storms or extended periods of non-use to prevent damage due to power surges. Avoid overloading power strips and extension cords to prevent fire or electric shock.

Installation
Avoid placing the monitor on unstable surfaces. Use only recommended carts, stands, or brackets to prevent injuries or damage. Do not insert objects into monitor slots or spill liquids on it. Maintain proper ventilation around the monitor to prevent overheating and potential fire hazards. If wall-mounting, use approved mounting kits and follow instructions carefully.

Cleaning
Regularly clean the monitor cabinet with a water-dampened, soft cloth. Use a soft cotton or microfiber cloth that is almost dry to prevent liquid damage. Disconnect the power cord before cleaning.

Other
If the monitor emits a strange smell, sound, or smoke, immediately disconnect the power plug and contact a Service Center for assistance.

Safety

National Conventions
The following subsections describe 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 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 a 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.

Unplug the unit during a lightning storm or when it will not be used for long periods. 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.

For use only with the attached power adapter.

Manufacturers: Ten Pao Industrial Co., Ltd Model: S025ANP1900131

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 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.

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 the monitor.
No images 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 VGA cable) Check the VGA cable connection. (Connected using the HDMI cable) Check the HDMI cable connection. (Connected using the DP cable) Check the DP cable connection. * VGA/HDMI/DP 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 Ghosting and Shadowing problems	Adjust the Contrast and Brightness Controls. Press the hot-key (AUTO) to auto-adjust. Make sure you are not using an extension cable or switch box. We recommend plugging the monitor directly to 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 fromMonitor ass much 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 the RGB color or select the desired color temperature.
Horizontal or vertical disturbances on the screen	Use Windows 7/8/10 shutdown mode to adjust CLOCK and FOCUS. Press the hot-key (AUTO) to auto-adjust.
