STOP OPERATING THE MONITOR WHEN YOU SENSE TROUBLE
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.
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 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.
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.
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 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 fire or damage. Operating the monitor on its back, side, upside down or on a carpet or any other soft material may also cause damage.

INSTALLATION
CAUTION
■ Follow the manual instructions for the type of mount you have selected. Refer all servicing to qualified service personnel.
■ Moving the monitor requires at least two people.
■ Before installing, please make sure the wall is strong enough to hold the necessary weight of the display and the mount.
[VENTILATION REQUIREMENTS FOR ENCLOSURE MOUNTING]
CAUTION
Don't block the holes in the rear of the monitor shown in the figure above. If they are blocked, heat accumulates inside the monitor, causing breakdown. The upper limit of the operation guaranteed ambient temperature when the monitor is installed in the landscape position is 40°C. When installing the monitor in a case or an enclosure, ensure adequate ventilation to keep the temperature inside the case 40°C or lower by providing a cooling fan or ventilation holes in the case. The upper limit when the monitor is in the portrait or face-up position is 35°C. This LCD has a temperature sensor and cooling fan. If the LCD becomes hot, the cooling fan will turn on automatically. If the LCD becomes overheated, the "Caution" menu will appear. If the "Caution" menu appears, stop using the monitor and allow it to cool. When the LCD display is used in an enclosure or with protection on LCD surface, please check the inside temperature of the monitor by "HEAT STATUS" (See page 42). If the temperature is higher than the normal level, set "COOLING FAN" to ON using the SCREEN SAVER function (See page 35).

Don't block these holes.[TO AVOID THE MONITOR FROM FALLING]
CAUTION
When installing the monitor using the tabletop stands (option), take measures to prevent the monitor from falling over in case of an earthquake or other disaster to lessen the probability of injury and damage resulting from the fall. As shown in the figure, secure the monitor to a solid wall or pillar using rope (commercially available) strong enough to bear the weight of the monitor. [approximately 30.1 kg (with the optional stands)] When using screw hooks (commercially available), use ring hooks, not C-hooks (with opening).

text_image
Screw holes 400 mm Screw hook, etc. (commercially available) Clamper Screw Rope, etc. (commercially available)CAUTION
- The effect of the fall prevention substantially depends on the strength of brackets and base to which the fall prevention devices is attached. When you cannot ensure sufficient strength, provide adequate reinforcement.
- Though the recommended fall prevention is intended to lessen the probability of injury and damage, it doesn't assure its effectiveness against any kind of earthquake or disaster.
- Do not sleep where the monitor may topple over or fall in case of an earthquake or other disaster.
- Before moving the monitor, remove the rope that is securing the monitor. Failure to do so may result in injury or breakdown of the monitor.
[USING THE WALL MOUNT OR CEILING MOUNT]
Lay the screen face down
Lay the protective sheet on a table, which was wrapped around the monitor when it was packaged, beneath the screen surface so as not to scratch the screen surface.
This device cannot be used or installed without the Tabletop Stand or other mounting accessory. Failure to follow the correct mounting procedures can result in damage to the equipment or injury to the user or installer. Product warranty does not cover damage caused by improper installation. Failure to follow these recommendations can void your warranty.

[SUPPLEMENTAL INFORMATION OF THE AUTO BRIGHTNESS FUNCTION]
To control multiple monitors collectively
In such a case where the tiling function is used, you can control the auto brightness function by sharing the detection result of the brightness sensor of a certain monitor among the connected monitors.
- Multi-connect the monitors using RS-232C cables (commercially available) as shown by the example below.

E <--> F["Monitor ID = 4 (Slave)"]
G["Monitor ID = 3 (Slave)"] <--> H["Monitor ID = 2 (Slave)"]
H <--> I["Monitor ID = 1 (Master)"]
Master: Monitor configured as Master that detects the outside light (Monitor ID is "1".)
Slave: Monitor controlled by the Master monitor (Monitor ID is other than "1".)
- Assign a monitor ID to each multi-connected monitors using MONITOR ID. (See page 38.) Monitor ID is selectable from 1 to 26. The monitor ID of the Master monitor should be "1" and those of the Slave monitors should be other than "1". You are recommended to assign IDs to the monitors consecutively from 1, 2, 3, and on.
- Set AUTO BRIGHTNESS on the OSD screen (PICTURE) as follows.
| AUTO BRIGHTNESS | CONTROL | |
| Master monitor | LOCAL | PRIMARY |
| Slave monitors | REMOTE | SECONDARY |
To use a computer to control the monitors
When using a computer to control the monitors, you must prepare an application software program for control by yourself. Brightness of all the monitors can be controlled centrally using a computer, if the customer create a control application to remotely read the value from two brightness sensors of any monitor and distribute it to all monitors.
- Connect the RS-232C IN connector of the Master monitor shown above and the RS-232C connector of the computer using an RS-232C cable. The communication control function via LAN isn't supported on the monitor alone, however, it is available when the monitor is used with the computer.
- Assign a monitor ID to each multi-connected monitors using MONITOR ID. (See page 38.) Monitor ID is selectable from 1 to 26.
- Set AUTO BRIGHTNESS on the OSD screen (PICTURE) as follows.
| AUTO BRIGHTNESS | CONTROL | |
| Master monitor | REMOTE | SECONDARY |
| Slave monitors | REMOTE | SECONDARY |
- A control application made by the customer reads the value from two brightness sensors of any monitor and distributes it to all monitors. For the specifications of the communication commands, contact your dealer.
[REMOTE CONTROL NUMBERING FUNCTION]
By connecting multiple monitors using RS-232C cables, you can control any one monitor or all the monitors by one remote controller.
- Assign arbitrary ID number to each of multi-connected monitors using MONITOR ID. ID numbers 1 to 26 are selectable. It is recommended to assign sequential ID numbers from 1 and up.
- The remote control mode of the first monitor is set to PRIMARY and those of the other monitors are set to SECONDARY.
- When you direct the remote controller at the remote control signal sensor of the PRIMARY monitor and press the DISPLAY button on the remote controller, the ID selection OSD appears at the upper left of the screen.

ID number of the currently viewed monitor
Select the ID number of the monitor you want to control using the +/- button on the remote controller. The ID of the monitor you want to control is displayed at the upper left of its screen. By selecting ALL, you can control all the multi-connected monitors.
- Direct the remote controller at the remote control signal sensor of the PRIMARY monitor. OSD appears on the monitor having the ID number you selected.
When the ID selection OSD is being displayed on the PRIMARY monitor, press the DISPLAY button on the remote controller again to cancel the ID selection OSD and then control the monitor you selected. If you set the remote control mode wrongly and remote control operation becomes unavailable, press any button on the control panel of the monitor to display the OSD screen and change the remote control mode using ADVANCED OPTION. By pressing and holding down the DISPLAY button on the remote control for 5 seconds or longer, the remote control mode is initialized to NORMAL.
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 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 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.
① Display the picture at the optimum resolution.
② Enter the Test.bmp (screen adjustment pattern) to wallpaper.
NOTE
■ Consult the appropriate documentation for doing this.
■ Test.bmp is made at resolution of 1280 × 1024. Set the display position to center in the wallpaper setting dialogue box. If you use Microsoft® PLUS! 95/98 cancel the setting of "Stretch desktop wallpaper to fit the screen".
