1. Determine the installation location
CAUTION:Installing your LCD display must be done by a
qualified technician. Contact your dealer for
more information.
CAUTION:
MOVING OR INSTALLING THE LCD MONITOR
MUST BE DONE BY TWO OR MORE PEOPLE
(P401/P461), BY FOUR OR MORE PEOPLE
(P521). Failure to follow this caution may result in
injury if the LCD monitor falls.
CAUTION:Do not mount or operate the display upside
down, face up, or face down.
CAUTION:This LCD has a temperature sensor and cooling
fan. If the LCD becomes too hot, the cooling fan
will turn on automatically. If the LCD becomes
overheated while the cooling fan is running, a
“Caution” warning will appear. If the “Caution”
warning appears, discontinue use and allow the
unit to cool. Using the cooling fan will reduce the
likelihood of early circuit failure and may help
reduce image degradation and “Image
Persistance”.
If the LCD is used in an enclosed area or if the
LCD panel is covered with a protective screen,
please check the inside temperature of the
monitor by using the “HEAT STATUS” control in
the OSD (see page 24). If the temperature is
higher than the normal operating temperature,
please turn the cooling fan to ON within the FAN
CONTROL menu within the OSD (see page 24).
IMPORTANT:Lay the protective sheet, which was wrapped
around the LCD monitor when it was
packaged, beneath the LCD monitor so as
not to scratch the panel.
2. Install the remote control batteries
The remote control is powered by two 1.5V AA batteries.
To install or replace batteries:NEC recommends the following battery use:
•Place “AA” size batteries matching the (+) and (-) signs
on each battery to the (+) and (-) signs of the battery
compartment.
•Do not mix battery brands.
•Do not combine new and old batteries. This can shorten
battery life or cause liquid leakage of batteries.
•Remove dead batteries immediately to prevent battery
acid from leaking into the battery compartment.
•Do not touch exposed battery acid, it may injure skin.
NOTE:If you do not intend to use the Remote Control for a
long period of time, remove the batteries.
3. Connect external equipment
(See pages 14 and 15)
•To protect the external equipment; turn off the main
power before making connections.
•Refer to your equipment user manual for further
information.
NOTE:Do not connect/disconnect cables when turning on
the monitor or other external equipment as this may
result in a loss of the monitor image.
4. Connect the supplied power cord
•The equipment should be installed close to an easily
accessible power outlet.
•Please fasten power cord to the LCD monitor by
attaching the screw and clamp.
•Fully insert the prongs into the power outlet socket.
A loose connection may cause image degradation.
NOTE:Please refer to the “Safety Precautions and
Maintenance” section of this manual for proper
selection of AC power cord.
Setup
A. Press and slide to open the cover.
B. Align the batteries according to the (+) and (–)
indications inside the case.
C. Replace the cover.
CAUTION:Incorrect usage of batteries can result in leaks
or bursting.

6. Switch on the power of all the attached
external equipment
When connected with a computer, switch on the power of
the computer first.
7. Operate the attached external
equipment
Display the signal from the desired input source.
8. Adjust the sound
Make volume adjustments when required.
9. Adjust the screen (See pages 20 and 21)
Make adjustments of the screen display position when
necessary.
10. Adjust the image (See page 20)
Make adjustments such as brightness or contrast when
required.
11. Recommended Adjustments
To reduce the risk of the “Image Persistence”, please adjust
the following items based on the application being used:
“SCREEN SAVER”, “SIDE BORDER COLOR” (See page 24)
“DATE & TIME”, “SCHEDULE SETTINGS” (See page 21).
It is recommended that the “FAN CONTROL” setting
(See page 24) be turned to ON also.
5. Attach the cable cover
•Use six of the M4 x 10 screws (included) to attach the
cable cover.
 
						

							English-14
Connections
NOTE:Do not connect/disconnect cables when turning on the monitor or other external equipment as this may result in a
loss of the monitor image.
NOTE:Use an audio cable without a built-in resistor. Using an audio cable with a built-in resistor turns down the sound.
Before making connections:
*First turn off the power of all the attached equipment and make connections.
*Refer to the user manual included with each separate piece of equipment.

Connecting a Personal Computer
Connecting your computer to your LCD monitor will enable you to display your computer’s screen image.
Some video cards with a pixel clock over 162MHz may not display an image correctly.
Your LCD monitor displays proper image by adjusting the factory preset timing signal automatically.

•If you use with a Macintosh PowerBook, set “Mirroring” to Off on your PowerBook.
Refer to your Macintosh’s owner’s manual for more information about your computer’s video output requirements and any
special identification or configuration your monitor’s image and monitor may require.
•Input TMDS signals conforming to DVI standards.
•To maintain display quality, use a cable that conforms to DVI standards.
Connecting a DVD Player with HDMI out
•Please use an HDMI cable with HDMI logo.
•It may take a moment for the signal to appear.
•PC-DVI signals are not supported.
Connecting a Computer with DisplayPort
•Please use DisplayPort cable with DisplayPort certified logo.
•It may take a moment for the signal to appear.
•Please note that DisplayPort connector does not supply power to the connected component.
•Please note that when connecting a DisplayPort cable to a component with a signal conversion adapter, an image may not
appear.
•Select DisplayPort cables feature a locking function. When removing this cable, hold down the top button to release the
lock.

Using Power Management
The LCD monitor follows the VESA approved DPM Display
Power Management function.
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:Depending on the PC and video card used, this
function may not operate.
Selecting a video source
To view a video source:
Use the input button to set [VIDEO1], [VIDEO2], [S-VIDEO].
Use the COLOR SYSTEM menu to set [AUTO], [NTSC],
[PAL], [SECAM], [PAL60], [4.43NTSC], according to your
video format.
