power company. Use only with UL listed computers within the
specified voltage range.
Installation
Place the monitor on a stable surface recommended by the
manufacturer. Do not insert objects into the monitor slots or spill
liquids on it. When wall-mounting, use an approved mounting kit and
follow instructions carefully. Maintain proper ventilation around
the monitor to prevent overheating.
Cleaning
Regularly clean the monitor cabinet with a water-dampened, soft
cloth. Disconnect the power cord before cleaning and ensure the
cloth is not too wet to prevent liquid damage.
Other
If you notice any unusual smells, sounds, or smoke coming from
the product, immediately disconnect the power plug and seek
assistance from a Service Center.

Frequently Asked Questions (FAQ)
Q: Can I use the monitor with a power strip or extension
cord?
A: Avoid overloading power strips and extension cords to prevent
fire or electric shock. Plug the monitor directly into a grounded
power outlet.
Q: What should I do if the monitor tilts downward more than -5
degrees?
A: To prevent potential damage not covered under warranty,
ensure the monitor does not tilt downward beyond -5 degrees. Adjust
the mounting or placement to avoid exceeding this limit.

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 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.
1
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 which 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.
2
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:
Installed with stand
12 inches 30cm
4 inches 10cm
4 inches 10cm
Leave at least this much space around the set
4 inches 10cm
3
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.
4
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.

Make sure the power button is ON and the Power Cord is properly connected to a
grounded power outlet and to the monitor.
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 DP cable)
Check the DP cable connection. * 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 the 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. 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 to the video card output connector on the back. 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. 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.
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.
Adjust H-Position and V-Position or press hot-key (AUTO).
Adjust RGB color or select desired color temperature.
Use Windows 7/8/10/11 shut-down mode to adjust CLOCK and FOCUS. Press hot-key

Plug and Play
Plug & Play DDC2B Feature This monitor is equipped with VESA DDC2B
capabilities according to the VESA DDC STANDARD. It allows the monitor to
inform the host system of its identity and, depending on the level of DDC
used, communicate additional information about its display capabilities. The
DDC2B is a bi-directional data channel based on the I2C protocol. The host can
request EDID information over the DDC2B channel.
