Power Indicator
Using Power Management
The LCD monitor follows the VESA approved DPM 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.
Selecting a video source
To view a video source:
Use the input button to set [VIDEO(S)] or [VIDEO].
Use the COLOR SYSTEM menu to set [AUTO], [NTSC],
[PAL], [SECAM], [PAL60], [4.43NTSC], according to your
video format.

NOTE 1: CREATING A SCHEDULE
Using the “SCHEDULE” function allows you to set up to seven different scheduled time intervals when the LCD Monitor will be activated.
You can select the time the monitor turns on and turns off, the day of week the monitor is activated, and which input source the monitor will
use for each scheduled activation period. A check mark in the box next to the number of the schedule indicates that the selected schedule
is in effect.
To select which schedule to set, use the up/down arrows to move the number (1 to 7) of the schedule.
Use the (+) and (-) buttons to move the red bar horizontally within the particular schedule. The “SET” button is used to make a selection.
If you create a schedule but do not want to use a power on time, select “--” in the “ON” time slot.
If you do not want to use a power off time select “--” in the OFF time slot.
If there is no input selected (“--” showing in the input spot) the input from the previous schedule will be used.
The selection of EVERY DAY within a schedule takes priority over other schedules that are set up to operate weekly.
When schedules are overlapping, scheduled Power ON time has priority over scheduled Power OFF time.
Note: If schedules are overlapping then the schedule with the highest number will have priority over the schedule with the lowest number.
For example schedule #7 will have priority over schedule #1.
NOTE 2: 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.
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 as Public Display
< Image Sticking of LCD Panel >
When an 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 may be permanent. (Image Sticking)
< Recommendations >
To prevent Image Sticking, and for longer life usage of LCD, the following are recommended.
1. Fixed image should not be displayed for long period. Change fixed images after short intervals.
2. When not in use, please turn off the monitor by remote control, or use Power Management or use Schedule Functions.
3. Lower environmental temperatures prolong the lifespan of the monitor.
When Protective surface (glass, acrylic) is installed over the LCD surface, the LCD surface is located in an enclosed space, the monitor
are stacked, utilize the temperature sensors inside monitor.
To reduce the environmental temperature, use the Cooling Fan, Screen Saver and Low Brightness.
4. Please use “Screen Saver Mode” of monitor.

Controlling the LCD monitor via RS-232C Remote Control
This LCD monitor can be controlled by connecting a personal computer with a RS-232C terminal.
Functions that can be controlled by a personal computer are:
•Power ON or OFF
•Switching between input signals
Connection
LCD Monitor + PC
RS-232C Cable PC (Out)RS-232C (IN) MultiSync
NOTE:If your PC (IBM or IBM compatible) is equipped only with a 25-pin serial port connector, a 25-pin serial port adapter is
required. Contact your dealer for details.
*In order to function, the RS-232C OUT terminal can only be connected to another monitor of the same model.
Do not connect to other types of equipment.
To control monitor or multiple monitors that are daisy-chained together please use the control command. Instructions for the
control command can be found on the CD included with the display. The file is called “External_control.pdf”.

Features
Reduced Footprint: Provides the ideal solution for environments requiring superior image quality but with size and weight
limitations.
Color Control Systems: Allows you to adjust the colors on your screen and customize the color accuracy of your monitor to
a variety of standards.
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 for 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, 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 for 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: Shows one image over multiple screens with accuracy while compensating for bezel width.
ZOOM: Expands image size for horizontal and vertical direction.
Self-diagnosis: If an internal error should occur, a failure state will be indicated.
