SAFETY PRECAUTIONS
WARNING
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 fire or electric shock.
NEVER REMOVE THE CABINET
High voltage circuits are inside the monitor. Removing the cabinet may expose you to the danger of
fire 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 fire, 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 fire or electric
shock.
OPERATE UNDER THE SPECIFIED POWER SUPPLY
Be sure to operate the monitor only with the specified power supply. Use of an incorrect voltage will
cause malfunction and may cause fire or electric shock.
CORRECT USE OF THE AC ADAPTER
Use only the AC Adapter provided by iiyama. Any deviation from this by using another type of
adapter may result in damage to the accessory and the monitor by fire or electric shock.
DO NOT DISASSEMBLE THE AC ADAPTER
Disassembling the AC Adapter may expose you to the danger of fire or electric shock.
PROTECT THE CABLES
Do not pull or bend the AC adapter, 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 fire 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
ENGLISH
STOP OPERATING THE MONITOR WHEN YOU SENSE TROUBLE
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 fire, electric shock or damage. You should also avoid areas where the
sun shines directly on the monitor.
ENGLISH
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
fire. To allow adequate air circulation, place the monitor at least 10cm (or 4 inches) from any walls.
When removing the tilt stand, the ventilation slots on the back side of the monitor can be blocked.
This may overheat the monitor and may cause fire or damage. Make sure to allow enough
ventilation when removing the tilt stand. 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 fire 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 AC adapter, the power cable or signal cable, always pull it by the plug. Never pull
on the cable itself as this may cause fire 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.
CARE TO A HAND AND FINGERS!
 Careful attention is required not to catch your fingers or hands when you change the height or the angle.
 Injury can occur if care is not taken to avoid finger contact with the displays base when adjusting
the height. (Just for height adjustable model.)
REMARK FOR 24/7 USAGE
This product is not specifically designed for 24/7 usage in all environments.
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.

SCREEN ADJUSTMENTS
ENGLISH
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
flicker or blur for the particular computer in use.
 The monitor is designed to provide the best performance at resolution of 1920 × 1080, but can not
provide the best at resolutions of less than 1920 × 1080 because the picture is automatically stretched
to fit the full screen. It is recommended to operate at resolution of 1920 × 1080 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 Adjust depending on the resolution or signal timing.
 The Auto 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 H/V-Position, Clock
and Phase. The other way is performing each adjustment manually.
Perform the Auto Adjust first when the monitor is connected to a new computer, or resolution is
changed. If the screen has a flicker or blur, or the picture does not fit in the display area after performing
the Auto 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).
Adjust the image by following the procedure below to get the desired picture.
This manual explains adjustment under Windows® OS.
Display the picture at the optimum resolution.
Enter the Test.bmp (screen adjustment pattern) to wallpaper.
NOTE  Consult the appropriate documentation for doing this.
 Set the display position to center in the wallpaper setting dialogue box.

adjusting the Clock.
NOTE  When the left side of the picture frame moves apart from the left edge of the display
area during the Clock adjustment, adjust steps 1) and 2).
 Another way to make the Clock adjustment is to correct the vertical wavy lines in the
