•Do not cover vent on monitor.
•If monitor or glass is broken, do not come in contact with the liquid crystal and handle with care.
Immediately unplug your monitor from the wall outlet and refer servicing to qualified service personnel under the following
conditions:
•When the power supply cord or plug is damaged.
•If liquid has been spilled, or objects have fallen into the monitor.
•If the monitor has been exposed to rain or water.
•If the monitor has been dropped or the cabinet damaged.
•If the monitor does not operate normally by following operating instructions.
•Allow adequate ventilation around the monitor so that heat can properly dissipate. Do not block ventilated
openings or place the monitor near a radiator or other heat sources. Do not put anything on top of
monitor.
•The power cable connector is the primary means of detaching the system from the power supply. The
monitor should be installed close to a power outlet which is easily accessible.
•Handle with care when transporting. Save packaging for transporting.
Image Persistence: Image persistence is 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.
NOTE: As with all personal display devices, NEC DISPLAY SOLUTIONS recommends using a moving screen saver at regular
intervals whenever the screen is idle or turning off the monitor when not in use.
CAUTION

CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR CAN
REDUCE EYE, SHOULDER AND NECK FATIGUE. CHECK THE
FOLLOWING WHEN YOU POSITION THE MONITOR:
•For optimum performance, allow 20 minutes for warm-up.
•Adjust the monitor height so that the top of the screen is at or slightly below eye level.
Your eyes should look slightly downward when viewing the middle of the screen.
•Position your monitor no closer than 40 cm and no further away than 70 cm from your
eyes. The optimal distance is 50 cm.
•Rest your eyes periodically by focusing on an object at least 20 feet away. Blink often.
•Position the monitor at a 90° angle to windows and other light sources to minimize glare
and reflections. Adjust the monitor tilt so that ceiling lights do not reflect on your screen.
•If reflected light makes it hard for you to see your screen, use an anti-glare filter.
•Clean the LCD monitor surface with a lint-free, non-abrasive cloth. Avoid using any
cleaning solution or glass cleaner!
•Adjust the monitor’s brightness and contrast controls to enhance readability.
•Use a document holder placed close to the screen.
•Position whatever you are looking at most of the time (the screen or reference material) directly in front of you to minimize
turning your head while you are typing.
•Avoid displaying fixed patterns on the monitor for long periods of time to avoid image persistence (after-image effects).
•Get regular eye checkups.
Ergonomics
To realize the maximum ergonomics benefits, we recommend the following:
•Adjust the Brightness until the background raster disappears.
•Do not position the Contrast control to its maximum setting.
•Use the preset Size and Position controls with standard signals.
•Use the preset Colour Setting.
•Use non-interlaced signals with a vertical refresh rate of more than 60 Hz.

Features
Triple input Technology: Triple input technology allowing up to 3 input sources to be connected to a single monitor. The DVI-I connector
supports both analog and digital input signals. Legacy analog input is supported using a traditional 15-pin VGA connector. Triple input
Technology provides traditional technology compatibility for analog as well as DVI-based digital compatibility for digital inputs. DVI-based
digital interfaces include DVI-D, DFP and P&D.
DVI-I: The integrated interface ratified by the Digital Display Working Group (DDWG) that allows both digital and analog connectors off of one
port. The “I” stands for integration for both digital and analog, The digital portion is DVI-based.
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.
DFP (Digital Flat Panel): An all-digital interface for flat panel monitors which is signal compatible with DVI. As a DVI-based digital only
connection, only a simple adapter is necessary for compatibility between DFP and other DVI-based digital connectors such as DVI and P&D.
P&D (Plug and Display): The VESA standard for digital flat panel monitor interfaces. It is more robust than DFP since it allows for other
options off a signal connector (options like USB, analog video and IEEE-1394-995). The VESA committee has recognized that DFP is a
subset of P&D. As a DVI-based connector (for the digital input pins), only a simple adapter is necessary for compatibility between P&D and
other DVI-based digital connector such as DVI and DFP.
Pivoting Stand: Allows users to adjust the monitor to the orientation that best fits their application, either Landscape orientation for wide
documents, or Portrait orientation for the ability to preview a full page on one screen at one time. The Portrait orientation is also perfect for full
screen video conferencing.
Reduced Footprint: Provides the ideal solution for environments requiring superior image quality but with size and weight limitations. The
monitor’s small footprint and low weight allow it to be moved or transported easily from one location to another.
Color Control Systems: Allows you to adjust the colours on your screen and customize the colour accuracy of your monitor to a variety of
standards.
Natural color matrix: 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.
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.
ErgoDesign Features: Enhance human ergonomics to improve the working environment, protect the health of the user and save money.
Examples include OSD controls for quick and easy image adjustments, tilt base for preferred angle of vision, small footprint and compliance
with MPRII and TCO guidelines for lower emissions.
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.
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.
Multiple Frequency Technology: Automatically adjusts monitor to the display card’s scanning frequency, thus displaying the resolution
required.
FullScan Capability: Allows you to use the entire screen area in most resolutions, significantly expanding image size.
Wide Viewing Angle Technology: Allows the user to be able to see the monitor from any angle (178 degrees) from any orientation —
Portrait or Landscape. Provides full 178° viewing angles either up, down, left or right.
VESA Standard Mounting Interface: Allows users to connect their MultiSync monitor to any VESA standard 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.
Visual Controller: Is a ground-breaking software family, developed by NEC Display Solutions, providing intuitive access to all monitor
setting controls and remote diagnosis via the Windows interface, based upon the VESA standard, DDC/CI. Using a standard VGA or DVI
signal cable, Visual Controller can either benefit single users or, with Visual Controller Administrator, can reduce the Total Cost of Ownership
through remote network-wide maintenance, diagnosis and asset-reporting.
Long cable capability automatic long cable compensation prevents image quality degradation caused by long cable lengths.
No-touch Auto Adjust (Analog input only): No-touch auto adjust automatically adjusts the monitor to optimal settings upon initial setup.
sRGB Color Control: A new optimized colour management standard which allows for colour matching on computer displays and other
peripherals. The sRGB, which is based on the calibrated colour space, allows for optimal colour representation and backward compatibility
with other common colour standards.
UNIFORMITY: This feature compensates for slight variations in the white uniformity level that may occur on the screen and improves the
colour and evens out the luminance uniformity of the display.
Response Improve: Improved gray to gray response.
Adjustable stand with pivot capability: Adds flexibility to your viewing preferences.
Quick Release stand: Allows fast removal.
Auto dimming technology: Automatically adjusts the backlight level depending on the level of ambient lighting.
