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.

may cause electric shock.
SAFETY PRECAUTIONS
ENGLISH
2 FOR YOUR SAFETY
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
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.
CAREFUL! PROTECT YOUR HANDS AND FINGERS
Be careful not to hurt your fi ngers or hands when you change the height or the angle.
Injury can occur if care is not taken to avoid fi nger contact with the displays base when adjusting
the height. (Just for height adjustable model.)
REMARK FOR 24/7 USAGE

22 OPERATING THE MONITOR
SCREEN ADJUSTMENTS
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 1920 × 1080, but can not
provide the best at resolutions of less than 1920 × 1080 because the picture is automatically stretched
to fi t 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 Position, Pixel Clock
and Phase. The other way is performing each adjustment manually.
Perform the Auto Adjust fi rst 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.
Consult the appropriate documentation for doing this.
Set the display position to center in the wallpaper setting dialogue box.

of the display area.
When the left side of the picture frame moves apart from the left edge of the display
area during the Pixel Clock adjustment, adjust steps 1) and 2).
Another way to make the Pixel Clock adjustment is to correct the vertical wavy lines
in the zebra pattern.
The picture may fl icker during the Pixel Clock, H.Position and V.Position adjustment.
In case the picture frame is bigger or smaller than the data display area after the
Pixel Clock adjustment, repeat steps from .
2) Stretch the right side of the picture frame to the right edge of the display area by
adjusting the Pixel Clock.
Pressing and holding of the INPUT Button for 2-3 seconds when the Menu is not

ENGLISH
24 OPERATING THE MONITOR
Adjust the Brightness and Color to get the desired picture after you complete the Pixel
Clock and Phase adjustments.
Put back your favorite wallpaper.
Adjust the Phase to correct horizontal wavy noise, fl icker or blur in the zebra pattern.
NOTE In case the strong fl icker or blurs remain on a part of the screen, repeat steps and
because the Pixel Clock may not be adjusted correctly.
Adjust the H.Position after the Phase adjustment if the horizontal position moves
during the adjustment.
ENGLISH
OPERATING THE MONITOR 25
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.
NOTE
POWER MANAGEMENT FEATURE
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
Management Mode, the image reappears in several seconds when either the keyboard or the
mouse are touched again.
The power management feature of this product complies with power saving requirement of ENERGY
STAR® 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.
