EnglishWhat You Can Do with This Monitor…
See low-light movie scenes more clearly and add more definition to digital camera images
•Dynamic Visual (DV) Mode: Pages 5, 7, 23 and 30
Dynamic Visual (DV) Mode provides the optimum image quality for different types of content, including movies, games,
photographs, and documents. Eight modes are available for PC Input or HDMI Input, and five modes are available for
Video Input.
Watch motion images clearly and sharply
•Motion Picture (MP) Mode: Pages 5, 7, 23 and 30
The newly-introduced Motion Picture Optimization Circuit helps to create sharp and less blurry images with during fast
motion scenes in games and movies by optimally combining three technologies: black screen insertion, backlight
scanning, and pixel overdrive.
Four levels of Motion Picture (MP) Mode are available according to the speed of motion in the image.
Enjoy images with less impact on your eyes
•Intelligent Visual (IV) Mode: Pages 24 and 30
Intelligent Visual (IV) Mode reduces the impact on your eyes by automatically controlling the screen brightness based on
ergonomic findings such as brightness perception differences according to the users’ age, and average brightness of the
current image.
Generally, settings for the younger age group are less bright, as their eyes are more sensitive to light.
Experience realistic sound created by the sound analysis and audio signal correction
•DIATONE
® Linear Phase Circuit
The newly-installed DIATONE® Linear Phase Circuit analyses the intensity and transmission speed of each frequency from
a speaker.
Frequency correction characteristics produced from the analyzed data are then applied to reproduce a clear and rich
sound.
Switch one computer screen to another on a single monitor
•Dual Input: Page 11
Two computers can be connected to the monitor and the display from each computer can be displayed alternately.
Maximum of four computers can be connected when HDMI inputs are used at the same time.
Control brightness and colors
•On Screen Display (OSD) Function: Page 20
On Screen Display (OSD) enables control of screen brightness, image position, size, and colors via the screen.
This screen also enables you to set the OSD Function itself (OSD auto-off, OSD lock, etc).
Adjust monitor angle and height
•Monitor Stand Adjustment: Page 16
The monitor is equipped with a specially designed stand. The height of the stand can be altered within a range of 60 mm
(at 0° tilt).
The stand’s tilt angle can be altered in four directions: up, down, right, and left.
Control LED brightness
•LED Brightness Adjustment Function: Pages 28 and 33
Brightness of the LED indicator can be lowered to reduce disturbance when watching dark scenes in a movie or multiple
display usage.
Watch a video while you’re working on the computer
•Picture-In-Picture (PIP) Function: Pages 27 and 33
Picture-In-Picture (PIP) displays a sub-screen within the main screen. This enables you to display a video screen in a
computer screen or vise versa. (PIP Function may not be available in some combinations.)
NOTE:An LCD monitor is manufactured with high precision technology and some LCD may have some permanently lit or
unlit dots. This is common to all LCD monitors and not specific to NEC monitors.
The effective dot rate* of this monitor is 99.9995% or higher.
*The effective dot rate refers to the percentage of screen dots that NEC DISPLAY SOLUTIONS guarantees to
function correctly in the entire working dots in a given monitor.
According to ISO 13406-2, a picture element is described as a pixel, and a dot is described as a sub-pixel.
A pixel consists of three sub-pixels, each of which illuminates red, blue, or green. These sub-pixels provide color
and gradation to the corresponding pixel. In other words, a sub-pixel is an intra-pixel component that functions
independently of each other.
This monitor displays images generated from signals received from a PC, HDMI, or video input.

							English-8
Operating the Remote Control
Basic Operations
Point the remote controller towards the receptor on the
monitor while operating.
Caution:Cautions on Remote Control Operations:
•The remote controller supplied with this monitor
cannot operate a TV or video.
•The remote controller is designed to function
up to three meters in a straight line from the
monitor; however, it may not function or the
monitor response may be slow depending on
the angle of the controller to the monitor. If this
happens, operate the controller at a closer
position or in front of the monitor.
•Do not drop or give a strong impact to the
remote controller.
Do not allow the controller to get wet or leave it
in a humid place.
This may damage the controller.
•Do not leave the controller in direct sunlight.
Heat may deform the controller.
•If the remote controller does not function,
assume the battery is exhausted.
Replace with new batteries.
•Avoid any obstacle between the remote
controller and the receptor on the monitor.
Replacing Batteries
A. Open the battery case cover by pressing the latch on the
cover.
B. Align the batteries according to the (+) and (-) indications
inside the case.
C. Close the cover.
Caution:•Incorrect use of batteries can result in leaks or
an explosion. Be especially careful about the
following points.
•The supplied batteries are not rechargeable.
Do not attempt to recharge them.
•Make sure to align the batteries according to
the (+) and (-) indications inside the case.
•Do not mix different types of batteries as they
posses different characteristics.
•Do not combine new batteries with used ones.
This causes shorter battery life or leakage from
the batteries.
•Remove dead batteries immediately to prevent
the batteries leaking.
Don’t touch exposed battery liquid, it may
damage the skin. Wipe with a cloth if leakage
occurs.
If the battery liquid comes into contact with the
skin, rinse thoroughly with water.
NOTE:•The supplied batteries may be consumed
quickly according to the length of preceding
storage. Replace them in good time.
•If you do not intend to use the Remote Control
for a long period, remove the batteries from the
case and store them separately.
