STOP OPERATING THE MONITOR IF YOU ARE AWARE OF ANY PROBLEMS
If you notice any abnormal phenomena such as smoke, strange sounds or fumes, unplug the
monitor and contact your dealer or iiyama service center immediately. Further use may be
dangerous and can cause fi re or electric shock.
NEVER REMOVE THE CABINET
High voltage circuits are inside the monitor. Removing the cabinet may expose you to the danger of
fi re or electric shock.
DO NOT PUT ANY OBJECT INTO THE MONITOR
Do not put any solid objects or liquids such as water into the monitor. In case of an accident, unplug
your monitor immediately and contact your dealer or iiyama service center. Using the monitor with
any object inside may cause fi re, electric shock or damage.
INSTALL THE MONITOR ON A FLAT, STABLE SURFACE
The monitor may cause an injury if it falls or is dropped.
DO NOT USE THE MONITOR NEAR WATER
Do not use where water may be splashed or spilt onto the monitor as it may cause fi re or electric
shock.
OPERATE UNDER THE SPECIFIED POWER SUPPLY
Be sure to operate the monitor only with the specifi ed power supply. Use of an incorrect voltage will
cause malfunction and may cause fi re or electric shock.
ENGLISH
PROTECT THE CABLES
Do not pull or bend the power cable and signal cable. Do not place the monitor or any other heavy
objects on the cables. If damaged, the cables may cause fi re or electric shock.
ADVERSE WEATHER CONDITIONS
It is advisable not to operate the monitor during a heavy thunder storm as the continual breaks in
power may cause malfunction. It is also advised not to touch the plug in these circumstances as it
may cause electric shock.
FOR YOUR SAFETY 1
CAUTION
INSTALLATION LOCATION
Do not install the monitor where sudden temperature changes may occur, or in humid, dusty or
smoky areas as it may cause fi re, electric shock or damage. You should also avoid areas where the
sun shines directly on the monitor.
DO NOT PLACE THE MONITOR IN A HAZARDOUS POSITION
The monitor may topple and cause injury if not suitably located. Please also ensure that you do not
place any heavy objects on the monitor, and that all cables are routed such that children may not
pull the cables and possibly cause injury.
MAINTAIN GOOD VENTILATION
Ventilation slots are provided to keep the monitor from overheating. Covering the slots may cause
ENGLISH
fi re. To allow adequate air circulation, place the monitor at least 10 cm (or 4 inches) from any walls.
Do not remove the tilt stand when operating the monitor. Ventilation slots on the back of the
cabinet will be blocked and the monitor may overheat if the stand is removed. This may cause fi re
or damage. Operating the monitor on its back, side, upside down or on a carpet or any other soft
material may also cause damage.
DISCONNECT THE CABLES WHEN YOU MOVE THE MONITOR
When you move the monitor, turn off the power switch, unplug the monitor and be sure the signal
cable is disconnected. If you do not disconnect them, it may cause fi re or electric shock.
UNPLUG THE MONITOR
If the monitor is not in use for a long period of time it is recommended that it is left unplugged to
avoid accidents.
HOLD THE PLUG WHEN DISCONNECTING
To disconnect the power cable or signal cable, always pull it by the plug. Never pull on the cable
itself as this may cause fi re or electric shock.
DO NOT TOUCH THE PLUG WITH WET HANDS
Pulling or inserting the plug with wet hands may cause electric shock.
WHEN YOU INSTALL THE MONITOR ON YOUR COMPUTER
Be sure the computer is strong enough to hold the weight of the monitor, otherwise, you may
damage your computer.
DO NOT USE THE MONITOR FOR 24-HOURS CONTINUOUSLY
The monitor is not designed to work for 24-hours continuously, do not use the monitor for 24-hours
continuously.
OTHERS
ERGONOMIC RECOMMENDATIONS
To eliminate eye fatigue, do not operate the monitor against a bright background or in a dark room.
For optimal viewing comfort, the monitor should be just below eye level and 40-60 cm (16-24 inches)
away from your eyes. When using the monitor over a prolonged time, a ten minute break every hour
is recommended as looking at the screen continuously can cause eye strain.
2 FOR YOUR SAFETY

SCREEN ADJUSTMENTS
Adjust the image by following the procedure below to get the desired picture when selecting Analog input.
The screen adjustments described in this manual are designed to set image position and minimize
fl icker or blur for the particular computer in use.
The monitor is designed to provide the best performance at resolution of 2560 × 1440, but can not
provide the best at resolutions of less than 2560 × 1440 because the picture is automatically stretched
to fi t the full screen. It is recommended to operate at resolution of 2560 × 1440 in normal use.
Displayed text or lines will be blurred or irregular in thickness when the picture is stretched due to
the screen enlargement process.
It is preferable to adjust the image position and frequency with the monitor controls, rather than
the computer software or utilities.
Perform adjustments after a warm-up period of at least thirty minutes.
Additional adjustments may be required after the Auto Image Adjust depending on the resolution
or signal timing.
The Auto Image Adjust may not work correctly when displaying the picture other than the screen
adjustment pattern. In this case, manual adjustments are required.
There are two ways to adjust the screen. One way is automatic adjustment for Position, Clock and
Phase. The other way is performing each adjustment manually.
Perform the Auto Image Adjust fi rst when the monitor is connected to a new computer, or resolution
is changed. If the screen has a fl icker or blur, or the picture does not fi t in the display area after
performing the Auto Image Adjust, manual adjustments are required. Both adjustments should be
made by using the screen adjustment pattern (Test.bmp) obtained via the IIYAMA web site (http://
www.iiyama.com).

and VESA DPMS. When activated, it automatically reduces unnecessary power consumption
of the monitor when your computer is not in use.
To use the feature, the monitor needs to be connected to a VESA DPMS compliant computer.
There is a power management step the monitor takes as described below. The power management
function, including any timer settings is confi gured by the operating system. Check your operating
system manual for information on how this can be confi gured.
Power Management Mode
When the H-sync signal / V-sync signal / H and V sync signals from the computer are off, the
monitor enters into Power Management Mode which reduces the power consumption to less
than 0.5W. The screen becomes dark, and the power indicator turns to orange. From Power
ENGLISH
Management Mode, the image reappears in several seconds when either the keyboard or the
mouse are touched again.
NOTE
Even when using the power management mode, the monitor consumes electricity. Turn
off the Power Switch whenever the monitor is not in use, during the night and weekends,
to avoid unnecessary power consumption.
It is possible that the video signal from the computer may be on while the H or V sync
signal is missing. In this instance, the POWER MANAGEMENT feature may not work
properly.
