NOTE: • Connect the HDMI cable when both the media player and the monitor are powered off.
• Use an HDMI cable with the HDMI logo.
• Some HDMI cables and devices may not show an image correctly due to different HDMI specifications.
• If you are unable to view material via the digital inputs, this does not necessarily mean that the monitor is not
functioning properly. With the implementation of HDCP, there may be cases in which certain content is protected
by HDCP and might not be displayed due to the decision/intention of the HDCP community (Digital Content
Protection, LLC).
Connecting to audio equipment with ARC function

Setting the Remote Control ID Function
The remote control can be used to control up to 100 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 100 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 (see Figure 1). Using the remote in REMOTE CONTROL ID mode will
only operate one specific monitor within the group (see Figure 2).
To Set Remote Control ID
While holding down the REMOTE ID SET button on the remote control, use the
KEYPAD to input the Monitor ID (1-100) of the monitor to be controlled via remote.
The remote control can then be used to operate the monitor having that specific
Monitor ID number.
When 0 is selected or when the remote control is in normal mode, all monitors will
be operated.
To Set/Reset Remote Control Mode
ID Mode - To enter ID Mode press the REMOTE ID SET button and hold down for
2 seconds.
Normal Mode - To return to Normal Mode press the REMOTE ID CLEAR button
and hold down for 2 seconds.
NOTE: • In order for this feature to work properly, the monitor must be assigned
a Monitor ID number. The Monitor ID number can be assigned under
the SYSTEM menu in the OSD. See page 89.
• Point the remote control toward the remote sensor of the desired
monitor and press the REMOTE ID SET button. The MONITOR ID
number is shown on the screen when your remote control is in ID
mode.
Use the Remote Control to Control all Monitors in Range
1. On the remote control, press and hold down the REMOTE ID SET button while
using the keypad to input the REMOTE CONTROL ID number “0”.
2. All monitors within range of the remote control will now respond to keypad press.
NOTE: When the REMOTE ID is set to “0”, pressing REMOTE ID SET will make all monitors, within range of the remote signal,
show their Monitor ID on screen. This way you can easily see what the monitor ID is if you want to control a single
monitor, as described below.
Use the remote control to operate a monitor that has a specific MONITOR ID number assigned to it.
1. Set the [MONITOR ID] number for the monitor (see page 89). The [MONITOR ID] number can range from 1-100.
This [MONITOR ID] number allows the remote control to operate this specific monitor without affecting other monitors.
2. On the remote control, press and hold down the REMOTE ID SET button while using the keypad to input the REMOTE
CONTROL ID number (1-100). The REMOTE ID NUMBER should match the MONITOR ID number of the monitor to be
controlled.
3. Point the remote control toward the remote sensor of the desired monitor and press the REMOTE ID SET button.
The MONITOR ID number is shown in red on the monitor.
If the REMOTE CONTROL ID is “0”, then all monitors in range will show their particular MONITOR ID number in red.
If the MONITOR ID number is shown in white on the monitor, the MONITOR ID number and the REMOTE CONTROL ID are
not the same.

NOTE: When you use this function, [CONTROL TERMINAL] in [EXTERNAL CONTROL] should be [LAN] (see page 89).
To use a LAN connection, you are required to assign an IP address (see page 85). The monitor will obtain an IP address
automatically when connected to a DHCP network.
Example of LAN connection:
Server
Hub
NOTE: Use a category 5 or higher LAN cable.

HTTP Browser
Overview
Connecting the monitor to a network allows for remote control of the monitor from a computer connected to the same network.
This device uses “JavaScript” and “Cookies” and the browser should be set to accept these functions. Refer to the help files for
the web browser to change the settings to use JavaScript and Cookies.
To access the HTTP server, launch a web browser on a computer connected to the same network as the monitor and enter the
following URL in the web address field:
Network Setting
http://<the Monitor’s IP address>/index.html
NOTE: • The default IP address is assigned automatically to the monitor.
• NaViSet Administrator software for managing monitors over the network is recommended. It can be download from
the NEC Display website (See page 73).
• 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).
• If the monitor appears to be slow in response to commands or clicks on buttons in the browser, or the general speed
of operation is unacceptable, this may be due to network traffic or the settings on your network. Should this happen,
consult your network administrator.
• The monitor may not respond if the buttons shown on the browser are repeatedly pressed in rapid intervals. Should
this happen, wait a moment and repeat. If you still can’t get a response, turn the monitor off and then back on.
Preparation Before Use
Connect the monitor to the network, using a commercially available LAN cable, before attempting to use browser operations.
Operation with a browser that uses a proxy server may not be possible depending 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 been set will not be shown,
depending on the effectiveness of the cache, and the contents set from the browser may not be reflected in operation. It is
recommended that a proxy server is not used unless the network environment requires it.
Handling of the Address for Operation via a Browser
A host name can be used in the following cases (corresponding to the IP address of the monitor):
The host name must be registered in the domain name system (DNS) by the network administrator. You can then access the
network settings of the monitor via this registered host name by using a compatible browser.
If the host name has been configured in the “HOSTS” file of the computer being used, you can then access the network settings
of the monitor via this host name by 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.

Screen Image and Video Signal Issues
No picture
• The signal cable should be completely connected to the
display card/computer.
• The display card should be completely seated in its slot.
• Check the main Power Switch, it should be in the ON
position.
• Make sure both the computer and monitor are powered
on.
• Make sure that a supported resolution has been selected
on the display card or system being used. If in doubt,
please refer to the user’s manual of the display controller
or system to change the resolution.
• Check the monitor and your display card with respect to
compatibility and recommended signal timings.
• Check the signal cable connector for bent or pushed-in
pins.
• The monitor automatically goes into standby at the
preset time period after the video signal is lost. Press
the power on button on the remote control or press the
⏻ button on the monitor.
• If you unplug the signal cable when starting the
computer, images may not be shown. Turn off the
monitor and the computer and then connect the signal
cable and turn on the computer and the monitor.
• Check the [SLOT POWER] setting when you use Option
Board accessories.
• Check for HDCP (High-bandwidth Digital Content
Protection) content. HDCP is a system for preventing
illegal copying of video data sent over a digital signal.
If you are unable to view material via the digital inputs,
this does not necessarily mean that the monitor is not
functioning properly. With the implementation of HDCP,
there may be cases in which certain content is protected
by HDCP and might not be shown due to the decision/
intention of the HDCP community (Digital Content
Protection, LLC).
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, the image persistence of monitors is not
permanent, but a single still image being shown for a
long period of time should be avoided. To alleviate image
persistence, put the monitor into standby via remote
control or turn the monitor’s main power off for as long as
the previous image was shown. For example, if an image
was on the monitor for one hour and a residual image
remains, the monitor should be in standby or turned off
for one hour to erase the image.
NOTE: As with all personal display devices, NEC DISPLAY
SOLUTIONS recommends showing moving
images, using a moving screen saver, or changing
still images at regular intervals whenever the screen
is idle, or putting the monitor into standby or turning
it off when not in use.
The image is blinking
• If you use a signal repeater or distributor or a long
cable, this may cause image roughness or blink for a
moment. In this case please connect the cable to the
monitor directly without using a repeater or a distributor,
or replace the cable with a higher quality cable. Using
a twisted pair extender may cause image roughness
depending on the environment where the monitor is in or
the cable you are using. For further information please
ask your supplier.
• Some HDMI cables may not show a correct image.
If input resolution is 1920 x 2160, 3840 x 2160 or
4096 x 2160, please use an HDMI cable which is
approved to support 4K resolution.
English−64
The image is unstable, unfocused or swimming is
apparent
• The signal cable should be completely attached to the
computer.
• Please adjust settings in the [ADJUST] of the [PICTURE
MODE] by checking the image on the screen.
• When the display mode is changed, the OSD Image
Adjust settings may need to be re-adjusted.
• Check the monitor and your display card with respect to
compatibility and recommended signal timings.
• If text looks garbled, change the video mode to non-
interlaced and use a 60 Hz refresh rate.
• The image may be distorted when turning the power on
or changing the settings.
The image is not properly reproduced
• Use the OSD Image Adjust controls to increase or
decrease the coarse adjustment.
• Make sure that a supported resolution has been selected
on the display card or system being used.
• If in doubt, please refer to the user’s manual of the
display card or system to change the resolution.
Selected resolution is not displayed properly
• Check the Information OSD to verify the appropriate
resolution has been selected.
• If the resolution you set is over or under a range, an
“OUT of RANGE” window will appear in order to warn
you. Please set supported resolution at the connected
computer.
Video contrast is either too high or too low
• Check that the correct option for the VIDEO LEVEL is
selected for the input signal.
This only applies to video signals on the DisplayPort,
HDMI, and OPTION inputs.
– Blacks are crushed and whites are clipped -
change the VIDEO LEVEL to RAW.
Crushing blacks and clipping whites can occur when
the monitor’s VIDEO LEVEL is set to EXPAND while
the source video signal’s color levels are RGB Full
(RGB 0-255), causing lost details in the shadows
and highlights and the image appears overly high in
contrast.
– Blacks are dark grey and whites are dull -
change the VIDEO LEVEL to EXPAND.
Dulling blacks and whites can occur when the VIDEO
LEVEL is set to RAW while the source video signal’s
color levels are RGB Limited (RGB 16-235), which
effectively appears to prevent the monitor from
obtaining its full brightness range and the image
appears to be lacking in contrast.
Either light vertical or horizontal stripes may appear, depending on the specific image pattern. This is not a product fault or degradation.
Hardware Issues
⏻ button does not respond
• Unplug the power cord of the monitor from the AC outlet
to turn off and reset the monitor.

Additional Documentation
“NEC LCD Monitor - External Control” PDF document
This document defines the communications protocol for externally controlling and querying the monitor via either RS-232C or
LAN. The protocol uses encoded binary and requires calculation of checksums, and most functionality in the monitor can be
controlled using these commands. A simpler protocol is also available for less demanding applications (see below).
This document is available for download from the NEC Display Solutions website in your region.
A Python programming language based SDK (Software Development Kit) is also available that encapsulates this
communications protocol into a Python library for rapid development.
https://github.com/NECDisplaySolutions/necpdsdk
“Projector/Monitor Common ASCII Control Command - Reference Manual” PDF document
This document defines the communications protocol for externally controlling the basic functions of the monitor via LAN using a
simple English-like syntax. It is suitable for easy integration into existing control systems. Functionality such as controlling and
querying the power state, video inputs, volume, and status is available. The protocol uses ASCII encoding and doesn’t require
calculation of checksums.
This document is available for download from the NEC Display Solutions website in your region.

When enabled, this option can detect and change inputs when a signal is applied or lost. Allows for
customization of the input priority.
NOTE: This option is unavailable when these OSD menu options are enabled:
• [HUMAN SENSING] is [ENABLED] in the [AUTO DIMMING] settings in the [CONTROL] menu.
NONE The monitor does not search for video signal on the other input connections.
If video signal is lost on the current input, or if the monitor is manually switched to an input that does not
have video signal, the screen will go black and the LED will flash green. If [POWER SAVE] is enabled, the
monitor will enter power saving mode after the period of time set for [POWER SAVE] has passed.
FIRST DETECT*
3
The monitor does not search for a video signal on the other input connections while the current input has a
video signal.
If the current input connection does not have video signal present, the monitor will search for video signal
on the other video input connections. If a video signal is found, the monitor will switch from the current
input to the input with the active video source automatically.
LAST DETECT*
3
The monitor actively searches for a video signal on the other input connections, even while the current
video signal is present. When a new video signal source is applied to another input connection, the monitor
automatically switches to the newly found video source.
If the video signal is lost on the current input connection, the monitor will search for video signal on the
other video input connections. If a video signal is found, the monitor will switch from the current input to the
input with the active video source automatically.
CUSTOM DETECT The monitor only searches for video signal on the inputs selected for the priority numbers. If the signal
is lost, the monitor searches for signal in the priority order and automatically switches to the highest
priority input it finds with an active video signal. The monitor actively searches these inputs. If the current
signal input is not Priority 1 and a new signal is applied to the input assigned to Priority 1, the monitor will
automatically switch to the higher priority input.
NOTE: • [Media Player] will only work when a USB storage device is connected.

WEEE Mark (European Directive 2012/19/EU and amendments)
Disposing of your used product: In the European Union
EU-wide legislation as implemented in each Member State requires that used electrical and electronic products
carrying the mark (left) must be disposed of separately from normal household waste. This includes monitors
and electrical accessories, such as signal cables or power cords. When you dispose of such products, please
follow the guidance of your local authority or ask the shop where you purchased the product, or if applicable,
follow applicable legislation or agreement you may have. The mark on electrical and electronic products may
only apply to the current European Union Member States.
Outside the European Union
If you wish to dispose of used electrical and electronic products outside the European Union, please contact your local authority
and ask for the correct method of disposal.
For EU: The crossed-out wheeled bin implies that used batteries should not be put to the general household
waste! There is a separate collection system for used batteries, to allow proper treatment and recycling in
accordance with legislation.
According to EU directive 2006/66/EC and amendments, the battery can’t be disposed improperly. The battery shall be
separated to collect by local service.
