Network Setting by Using an HTTP Browser
Overview
Connecting the monitor to a network allows for monitor control from a co\
mputer via the network.
To perform the monitor control from a web browser, you must have an exclusive application installed on your computer.
The IP address and subnet mask of the monitor can be set on the Network Settin\
g screen of the web browser by using an HTTP 
server function. Please be sure to use “Microsoft Internet Explorer 6\
.0” or a higher version for the web browser.
(This device uses “JavaScript” and “Cookies” and the browse\
r should be set to accept these functions. The setting method will 
vary depending on the version of browser. Please refer to the help fi les and the other information provided in your software.)
Access is gained to the HTTP server function by starting the Web browser on the computer via the network connected to the 
monitor and entering the following URL.
Network Setting
http:///index.html
TIP:  The default IP address is “192.168.0.10”.
The exclusive application can be downloaded from our website.
NOTE:  If the MONITOR NETWORK SETTINGS screen does not appear in the web browser, press the Ctrl+F5 keys to 
refresh your web browser (or clear the cache).
The display or button’s response can be slowed down or operation may not be accepted depending\
 the settings of 
your network. Should this happen, consult your network administrator.
The LCD monitor may not respond if its buttons are repeatedly pressed in\
 rapid intervals. Should this happen, wait a 
moment and repeat. If you still can’t get a response, turn the monito\
r off and then back on.

Preparation Before Use
Connect the monitor to a commercially available LAN cable before engagin\
g in browser operations.
Operation with a browser that uses a proxy server may not be possible de\
pending on the type of proxy server and the setting 
method. Although the type of proxy server will be a factor, it is possible that items that have actually been set will not be 
displayed depending on the effectiveness of the cache, and the contents set from the browser may not \
be refl ected in operation. 
It is recommended that a proxy server not be used unless it is unavailab\
le.
Handling of the Address for Operation via a Browser
The host name can be used under the following cases:
If the host name corresponding to the IP address of the monitor has been registered to the domain name server (\
DNS) by the 
network administrator, you can then access the network settings of the display via that regis\
tered host name using a compatible  
browser.
If the host name corresponding to the IP address of the monitor has been confi gured in the “HOSTS” fi le of the computer being 
used, you can then access the network settings of the display via that h\
ost name using a compatible browser.
Example 1:  When the host name of the monitor has been set to “pd.nec.co.jp”, \
access is gained to the network setting by  specifying http://pd.nec.co.jp/index.html  for the address or the entry column of the URL.
Example 2:  When the IP address of the monitor is “192.168.73.1”, access is gained to the\
 mail alert settings by specifying  http://192.168.73.1/index.html  for the address or the entry column of the URL.
Network Settings
http:// /index.html
DHCP Enabling this option automatically assigns an IP address to the monitor from your DHCP server.
Disabling this option allows you to register the IP address or subnet mask number obtained from your 
network administrator.
NOTE:  Consult your network administrator for the IP address when [ENABLE] is selected for    
 [DHCP].
IP v4 Address  Set your IP address of the network connected to the monitor when [DISABLE] is selec\
ted for [DHCP].
Subnet Mask Set your subnet mask number of the network connected to the monitor when\
 [DISABLE] is selected  for [DHCP].
Default Gateway Set your default gateway of the network connected to the monitor when [D\

Reduced Footprint: 
Provides the ideal solution for environments with superior image quality\
.
Color Control Systems:  Allow you to adjust the colors on your screen and customize the color ac\
curacy of your monitor to a 
variety of standards.
OmniColor:  Combines Six-axis color control and the sRGB standard. Six-axis color c\
ontrol permits color adjustments via six 
axes (R, G, B, C, M and Y) rather than through the three axes (R, G and B) previously availab\
le. The sRGB standard provides 
the monitor with a uniform color profi le. This assures that the colors displayed on the monitor are exactly the sa\
me as on the 
color printout (with sRGB supporting operating system and sRGB printer)\
. This allows you to adjust the colors on your screen 
and customise the color accuracy of your monitor to a variety of standar\
ds.
sRGB Color Control:  A new optimized color management standard which allows for color matching\
 on computer displays and 
other peripherals. The sRGB standard, which is based on a calibrated color space, allows fo\
r optimal color representation and 
backward compatibility with other common color 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, signifi cantly expanding image size.
VESA Standard (FDMIv1) Mounting Interface:  Allows you to connect your LCD monitor to any VESA standard (FDMIv1) third 
party mounting arm or bracket. NEC recommends using mounting interface t\
hat comply with TÜV-GS and/or UL1678 standard 
in North America.
DVI-D:  The digital-only subset of DVI ratifi ed by the Digital Display Working Group (DDWG) for digital connections between 
computers and displays. As a digital-only connector, analog support is not provided for a DVI-D connector. As a DVI-based 
digital only connection, only a simple adapter is necessary for compatib\
ility 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:  Shows one image over multiple screens with accuracy while compensating f\
or bezel width.
ZOOM:  Expands image size for horizontal and vertical direction.
RS-232C daisy chain:  You can control the multiple monitors by controller or wireless remote co\
ntroller.
Self-diagnosis:  If an internal error should occur, a failure state will be indicated.
HDCP (High-bandwidth Digital Content Protection):  HDCP is a system for preventing illegal copying of video data sent over 
a Digital Visual Interface (DVI). If you are unable to view material via the DVI \
input, this does not necessarily mean the disp lay is 
not functioning properly. With the implementation of HDCP, there may be cases in which certain content is protected with HDCP 
and might not be displayed due to the decision/intention of the HDCP community (Digital Content Protection, LLC).
Option board slot:  You can use an option board. Please contact your supplier for detailed in\
formation.

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.
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.
