•
•
The ceiling and wall must be strong enough to support  
the monitor and mounting accessories.  
DO NOT install in locations where a door or gate can hit  
the unit.  
DO NOT install in areas where the unit will be subjected  
to strong vibrations and dust.  
DO NOT block ventilated openings with mounting  
accessories or other accessories.  
DO NOT install near where the main power supply  
enters the building.  
For NEC Qualified Personnel:  
Do not install in where people can easily grab and hang  
onto the unit or the mounting apparatus.  
To insure safe installation, use two or more brackets to  
mount the unit. Mount the unit to at least two points on the  
installation location.  
When mounting in a recessed area, as in a wall, leave at  
least 4 inches (10cm) of space between the monitor and  
the wall for proper ventilation.  
Please note the following when mounting  
on wall or ceiling  
•
Allow adequate ventilation or provide air conditioning  
around the monitor, so that heat can properly dissipate  
away from the unit and mounting apparatus.  
•
When using mounting accessories other than those that  
are NEC approved, they must comply with the VESA-  
compatible (FDMlv1) mounting method.  
Mounting on ceiling  
•
NEC strongly recommends  
•
Ensure that the ceiling is sturdy enough to support the  
weight of the unit and the mounting apparatus over time,  
against earthquakes, unexpected vibrations, and other  
external forces.

depth of hole (10mm) + the  
thickness of mounting bracket.  
•
•
Prior to mounting, inspect the installation location to  
insure that it is strong enough to support the weight of  
the unit so that the unit will be safe from harm.  
Maintenance  
•
Periodically check for loose screws, gaps, distortions, or  
other problems that may occur with the mounting  
apparatus. If a problem is detected, please refer to  
qualified personnel for service.  
Refer to the instructions included with the mounting  
equipment for detailed information.  
•
Regularly check the mounting location for signs of  
damage or weakness that may occur over time.  
Orientation  
•
When using the display in the portrait position, the  
monitor should be rotated clockwise so that the left side  
is moved to the top and the LCD indicator light is on the  
bottom. This will allow for proper ventilation and will  
extend the lifetime of the monitor. Improper ventilation  
may shorten the lifetime of the monitor.

The power management function is an energy saving  
function that automatically reduces the power consumption  
of the display when the keyboard or the mouse has not been  
used for a fixed period.  
The power management feature on your new display has  
been set to the “ON” mode. This allows your display to enter  
a Power Saving Mode when no signal is applied. This could  
potentially increase the life and decrease the power  
consumption of the display.

NOTE 2: IMAGE PERSISTENCE  
Please be aware that LCD Technology may experience a phenomena known as Image Persistence. Image Persistence occurs when a  
residual or “ghost” image of a previous image remains visible on the screen. Unlike CRT monitors, LCD monitors’ image persistence is not  
permanent, but constant images being displayed for a long period of time should be avoided.  
To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an image was on the  
monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase the image.  
As with all personal display devices, NEC DISPLAY SOLUTIONS recommends displaying moving images and using a moving screen  
saver at regular intervals whenever the screen is idle or turning off the monitor when not in use.  
Please set “SCREEN SAVER”, “DATE &TIME” and “SCHEDULE SETTINGS” functions to further reduce the risk of Image persistence.  
For long life use of Public Display  
< Image Sticking of LCD Panel >  
When LCD panel is operated continuously for long hours, a trace of electric charge remains near the electrode inside LCD, and residual or  
“ghost” image of previous image may be observed. (Image Persistence)  
Image Persistence is not permanent, but when fixed image is displayed for long period, ionic impurities inside LCD are accumulated along  
the displayed image, and it is observed permanently. (Image Sticking)  
< Recommendations >  
For preventing the fast transition to Image Sticking, and for longer life usage of LCD, following are recommended.  
1. Fixed image should not be displayed for long period, and changed to another images with short cycle.  
2. When no use, please turn off the monitor by remote control, or use Power Management Function of monitor or use Schedule Function of  
monitor.  
3. Reducing the environmental temperature is effective for long life use.  
When Protection board (glass, acryl) is installed over the LCD surface, enclosed into the box / wall, or stack the monitor, please utilize the  
temperature sensors inside monitor.  
To reduce the environmental temperature, the monitor should be set Low Brightness or Cooling Fan “ON” by using Screen sever Function.  
4. Please use “Screen Saver Mode” of monitor.  
Remote Control ID Function  
REMOTE CONTROL ID  
The remote control included with the display can be used to control up to 26 individual  
MultiSync monitors using what is called the REMOTE CONTROL ID mode. The REMOTE  
CONTROL ID mode works in conjunction with the Monitor ID, allowing control of up to 26  
individual MultiSync monitors. For example: if there are many monitors being used in the  
same area, a remote control in normal mode would send signals to every monitor at the  
same time Figure 1. Using the remote in REMOTE CONTROL ID mode will only operate  
one specific monitor within the group Figure 2.

Features  
Reduced Footprint: Provides the ideal solution for environments requiring superior image quality but with size and weight  
limitations.  
Colour Control Systems: Allows you to adjust the colours on your screen and customize the colour accuracy of your monitor  
to a variety of standards.  
OmniColor: Combines Six-axis colour control and the sRGB standard. Six-axis colour control permits colour adjustments via  
six axes (R, G, B, C, M and Y) rather than through the three axes (R, G and B) previously available. The sRGB standard  
provides the monitor with a uniform colour profile. This assures that the colours displayed on the monitor are exactly the same  
as on the colour printout (with sRGB supporting operating system and sRGB printer). This allows you to adjust the colours on  
your screen and customise the colour accuracy of your monitor to a variety of standards.  
sRGB Colour Control: A new optimized colour management standard which allows for colour matching on computer displays  
and other peripherals. The sRGB standard, which is based on a calibrated colour space, allows for optimal colour  
representation and backward compatibility with other common colour standards.  
OSD (On-Screen-Display) Controls: Allow you to quickly and easily adjust all elements of your screen image via simple to  
use on-screen menus.  
Plug and Play: The Microsoft® solution with the Windows® operating system facilitates setup and installation by allowing the  
monitor to send its capabilities (such as screen size and resolutions supported) directly to your computer, automatically  
optimizing display performance.  
IPM (Intelligent Power Manager) System: Provides innovative power-saving methods that allow the monitor to shift to a  
lower power consumption level when on but not in use, saving two-thirds of your monitor energy costs, reducing emissions  
and lowering the air conditioning costs of the workplace.  
FullScan Capability: Allows you to use the entire screen area in most resolutions, significantly expanding image size.  
VESA Standard (FDMIv1) Mounting Interface: Allows users to connect their LCD monitor to any VESA standard (FDMIv1)  
third party mounting arm or bracket. Allows for the monitor to be mounted on a wall or an arm using any third party compliant  
device. NEC recommends using mounting interface that comply with TÜV-GS and/or UL1678 standard in North America.  
DVI-D: The digital-only subset of DVI ratified by the Digital Display Working Group (DDWG) for digital connections between  
computers and displays. As a digital-only connector, analog support is not provided off a DVI-D connector. As a DVI-based  
digital only connection, only a simple adapter is necessary for compatibility between DVI-D and other DVI-based digital  
connectors such as DFP and P&D. The DVI interface of this display supports HDCP.  
TILE MATRIX, TILE COMP: Demonstrates multiple screens with an accurate image and compensates for the bezel width.  
ZOOM: Expands the image individually for horizontal and vertical direction.  
RS-232C daisy chain: You can control the multiple monitors by controller or wireless remote controller.  
Self-diagnosis: When an internal error should occur, a failure state will be indicated.  
CableComp: Automatic long cable compensation prevents image quality degradation (colour shift and dull signals) caused by  
long cable lengths.

Image persistence  
•
Please be aware that LCD Technology may experience a  
phenomenon known as Image Persistence. Image  
Persistence occurs when a residual or “ghost” image of a  
previous image remains visible on the screen. Unlike  
CRT monitors, LCD monitors’ image persistence is not  
permanent, but constant images being displayed for a  
long period of time should be avoided. To alleviate image  
persistence, turn off the monitor for as long as the  
previous image was displayed. For example, if an image  
was on the monitor for one hour and a residual image  
remains, the monitor should be turned off for one hour to  
erase the image.  
Check to see if volume is set at minimum.  
Remote Control is not available  
•
•
•
Check the Remote Control’s batteries status.  
Check if batteries are inserted correctly.  
Check if the Remote Control is pointing at the monitor’s  
remote sensor.  
•
•
Check the Remote Control Mode status.  
The remote control system may not function when direct  
sunlight or strong illumination strikes the remote control  
sensor of the LCD monitor, or when there is an object in  
the path.  
NOTE: As with all personal display devices, NEC DISPLAY  
SOLUTIONS recommends displaying moving  
images and using a moving screen saver at regular  
intervals whenever the screen is idle or turning off  
the monitor when not in use.  
“SCHEDULE”/“OFF TIMER” function is not working  
properly  
•
The “SCHEDULE” function will be disabled when the  
“OFF TIMER” is set.  
•
If the “OFF TIMER” function is enable and the power to  
the LCD monitor is turned off if the power supply is  
interrupted unexpectedly, then the “OFF TIMER” will be  
reset.  
Image is unstable, unfocused or swimming is apparent  
•
Signal cable should be completely attached to the  
computer.  
•
Use the OSD Image Adjust controls to focus and adjust  
display by increasing or decreasing the fine adjustment.  
When the display mode is changed, the OSD Image  
Adjust settings may need to be re-adjusted.  
RS-232C is not working  
•
Make sure the monitor is not in “Eco Standby” mode  
(see page 27).  
Snowy Picture, Poor Sound in TV  
•
•
Check the monitor and your display card with respect to  
compatibility and recommended signal timings.  
•
Check antenna/cable connection. Use new cable if  
necessary.  
If your text is garbled, change the video mode to non-  
interlace and use 60Hz refresh rate.  
Interference in TV  
•
Check components for shielding, move away from  
monitor if necessary.  
Image of component signal is greenish  
Check to see if the DVD/HD input connector is selected.  
•
LED on monitor is not lit  
(no green or red colour can be seen)  
•
Power Switch should be in the ON position and power  
cord should be connected.  
•
Make certain the computer is not in a power-saving  
mode (touch the keyboard or mouse).  
Either light vertical or horizontal stripes may appear, depending on the specific display pattern. This is no product fault or  
degradation.
