Precautions:
• ( Mac OS only) Do not use the ColorSync control panel to switch between different
monitor calibrations by selecting different monitor color proles. Always use the
MultiProler application to congure the display prole. This is because all of the
necessary color adjustments, including the Look Up Tables, are stored in the display
monitor and these must be set by MultiProler. The ColorSync proles generated by
MultiProler contain linear Look Up Tables for the video graphics adapter.
• Extreme care should be taken when using the DisplaySync Pro with certain USB
devices such as ash memory sticks and hard drives, as data can be lost or corrupted
if the device is switched between upstream ports while write operations are being
performed. Always use the device “eject” function on the host PC before switching
upstream ports with these types of devices.
Note:
This document covers both the Mac OS and Windows versions of the MultiProler software. The
features and functions of both versions are identical unless noted otherwise. The majority of the
User Interface screen images in this document show the Mac OS version, however the Windows
version is identical in layout unless noted otherwise.

Supported Display Monitors
MultiProler supports the following NEC display monitor models:
• MultiSync PA231W – 23” standard color gamut LCD monitor
• MultiSync P241W – 24” standard color gamut LCD monitor
• MultiSync PA241W – 24” wide color gamut LCD monitor
• MultiSync PA271W – 27” wide color gamut LCD monitor
• MultiSync PA301W – 30” wide color gamut LCD monitor
• MultiSync MD301C4 – 30” wide color gamut medical LCD monitor
MultiSync PA231W and P241W Important Note:
The color gamut of the PA231W and P241W displays are not wide color gamut, and are closer to
sRGB.
For this reason, certain preset color gamuts such as AdobeRGB and DCI are not available, since
they far exceed the color gamut of the display. Although MultiProler will allow the Picture
Mode settings to be modied to include large color gamuts, keep in mind that the actual color
gamut of the display is smaller, and will not be able to display colors outside of this gamut.
The PA231W display does not have an internal luminance stabilization circuit. It is therefore not
able to automatically set and maintain the luminance at an absolute value.
For this reason, the Brightness and Black Level controls are shown as a percentage values within
MultiProler.
The DICOM mode is called DICOM Sim (simulation) because the lack of an absolute level for
Brightness and Black Level means approximate values are used. True DICOM requires absolute
values for Brightness and Black Level in order to create a very accurate response curve.

1 Introduction to MultiProler
Overview
MultiProler is designed as a companion to NEC MultiSync PA Series monitors. It provides complete control over the
powerful and sophisticated technology in these models in an easy-to-use application.
NEC MultiSync PA Series monitors feature a custom-designed color processor called the SpectraView Engine. This
sophisticated processor, combined with internal luminance, temperature and time monitoring of the monitor, and
individual characterization and calibration of each unit during production, results in an unparalleled level of color control,
accuracy and stability.
The wide color gamut and high-contrast LCD panel used on the monitor, coupled with the SpectraView Engine, provide
the utmost in versatility; from the ability to accurately emulate colorspaces such as AdobeRGB and sRGB, to performing
printer output emulations using ICC Proles and internal 3D Look Up Tables.
Main Features and Benets
MultiProler provides a simple, intuitive interface to perform the following functions:
• Picture Mode preset conguration: Multiple color modes can be quickly congured and selected using
MultiProler. Choose from the simplicity of built-in sRGB, Adobe RGB, DCI, DICOM, REC-BT709 and High
Brightness modes, or load a device ICC prole for color matching a printer or even another monitor. A powerful
Wizard interface helps guide you through creating and customizing different custom Picture Mode congurations,
including controlling every aspect of the monitor such as the gamma characteristics, color gamut, white point,
and brightness.
• Picture-in-Picture (PIP) conguration: The powerful video processor in the MultiSync PA Series allows two
video signals to be viewed at once in a secondary PIP or Picture-by-Picture (PBP) window conguration. The
picture of the secondary window can even be congured to display in a different colorspace, allowing functions
like simultaneous viewing of printer emulations, or even human color vision deciencies.
• DisplaySync Pro and USB hub conguration: The USB hub integrated into the MultiSync PA Series can
also be managed through MultiProler to function as a Keyboard / Video / Mouse (KVM) switch. This feature
allows the mapping of the two USB upstream ports to the various monitor inputs, which is useful for managing
multiple computers attached to the unit.
• Automatic generation of ICC/ColorSync proles: MultiProler automatically generates and updates ICC
proles for the monitor as the color modes are selected or adjusted. This activity, coupled with the internal
stabilization and highly accurate characterization and calibration of each monitor during production, reduces the
need for a proling package to prole the monitor.
• Flexible: Communications with the monitor can be performed either through the video cable using the Display
Data Channel / Command Interface (DDC/CI), or via an USB upstream connection to the unit (using optional
USB cable). This allows for better compatibility with different host PC platforms.

10 | MULTIPROFILER - USER’S GUIDE
This Display Conguration dialog is accessed by clicking
the Display: Congure button in the main MultiProler
window.
If more than one display is being used on Windows, it may
be necessary to manually congure the relationship between
the display layout on the Windows desktop, and the display
that are connected to the system. Correct conguration of
this relationship is necessary so that the display adjustments
are sent to the correct unit, and that the generated ICC prole
is associated with the correct display.
A diagram depicting the display desktop layout is shown and
the display associated with each desktop screen is shown.
The monitor associated with each screen can be selected
using the listboxes.
Clicking on the display rectangles will also select different
displays on the Windows desktop.
If the display is connected to the host PC by using a USB
cable (not supplied) then it can also be controlled by USB
instead of the default DDC/CI interface. If a USB connection
is detected, the display name will be followed by “(USB)” in
the listbox. Select this to use the USB connection.
Note: Some video graphics adapters may show several duplicate displays due to issues with the video drivers
for that adapter. In this case the duplicate displays can be selected to “None”.
Auto Congure - Attempts to automatically detect and congure the display to the display layout on the
Windows desktop. In most cases this will correctly congure the correct relationship, but in some cases it may
be necessary to manually congure.
Test Monitor - Tests the communications with the currently selected display. Clicking this button will send a
command to ash the display power indicator LED between green and blue. If the wrong display ashes, then
change the monitor associated with the display by using the listboxes to select.
Display Conguration dialog ( ÿWindows version only)
Display Conguration button (ÿWindows version
only) opens the Display Conguration dialog, which
is used to congure MultiProler if more than one
monitor is used on the system, or to select between
using DDC/CI and USB interfaces to communicate
with the monitor .

11 | MULTIPROFILER - USER’S GUIDE
Picture Mode panel
The Picture Mode panel controls the settings for the
various Picture Modes that the monitor supports, as
well as adjusting the Brightness and Black Level.
The monitor supports 5 different congurable Picture
Modes that can be quickly selected by clicking on
the relevant buttons. Each Picture Mode can be
congured with different color settings by selecting
the desired Picture Mode to modify, and then clicking
Edit.... This will open the Color Conguration
Wizard.
As different Picture Modes are selected, MultiProler
will automatically generate an ICC/ColorSync prole
for the new color settings of the selected Picture
Mode. This prole will be automatically registered
with the Color Management System.
See the Picture Modes section for a more detailed
description.
Brightness
The Brightness slider and spinbox controls adjust the monitor brightness. The brightness is indicated in
Candelas per square meter (cd/m²) and represents an absolute value. The SpectraView Engine automatically
calculates and compensates the brightness value as color settings such as white point are changed.
The Brightness control will indicate when any range limits have been reached that impact the screen
performance:
Note: On the MultiSync PA231W model, the Brightness and Black Level controls are shown as percentages
instead of absolute luminance values. This is because the display does not have an internal luminance
stabilization circuit.
Too High - Is shown when
the Brightness level setting
is too high and can not be
achieved by the monitor with
the current setting. Lower
the setting until the message
disappears. It takes several
seconds to update the level
warning.
Note: The monitor takes a few
minutes after powering on for
the maximum brightness to
stabilize.
Uniformity - Is shown when
the Brightness control is set
above the range that the monitor
can achieve with the current
Digital Uniformity Compensation
setting.
In this case the monitor will
automatically reduce the
Uniformity correction level in
order to achieve the brightness
setting level.
See the Digital Uniformity section
for more information.

12 | MULTIPROFILER - USER’S GUIDE
Black Level
The Black Level slider and spinbox controls adjust the luminance of black on the screen and is set as an
absolute value in Candelas per square meter (cd/m²).
The Black Level, together with the Brightness setting determines the contrast ratio of the screen image. There
is a maximum limit to the contrast ratio of the screen, which is determined by the characteristics of the LCD
panel, in combination with ambient light scattering on the screen, which produces glare. Glare reduces the
perceived contrast ratio by raising the black level of the surface of the screen.
To achieve the maximum possible contrast ratio, set the Black Level control to 0.0 cd. The control will display
Minimum indicating that the Black Level will be set by the SpectraView Engine to be as low as possible.
Set the Black Level to a non-zero value to set the Black Level to a specic value.
If the Ambient Light Compensation setting is currently enabled, then the Black Level control will factor in
the impact of the ambient lighting glare on the screen on the perceived black level and adjust the monitor
accordingly.
The Black Level control will indicate when the selected value can not be achieved:
Note: The Ambient Light Compensation is only updated whenever the Brightness, Black Level or Picture
Mode controls are changed. The monitor will not otherwise update the black level based on the ambient light
sensor reading.
Reduced CR - Is shown when the Brightness control is set to a level where it impacts the
Contrast Ratio of the screen image. This occurs when the brightness setting is below that
which can be controlled using the LCD CCFL backlights alone.
When this range is entered, the monitor will automatically begin to reduce the brightness
to the requested value by using the internal 14-bit LUTs to scale the video signal. Since
this scaling is done internally to a high bit depth it will not introduce color banding, however
it will reduce the contrast ratio of the monitor.
The reason for this reduction in contrast ratio is because the black level is being maintained
constant (it is a xed property of the LCD panel once the minimum LCD CCFL backlight
level has been reached), but the white level is being scaled down - so the ratio of white
to black levels will be reduced.
Too Low - Is shown if the current Black Level setting can not be achieved either
because:
a) The setting is lower than that of the characteristics of the LCD panel with the current
Brightness setting.
b) If Ambient Light Compensation is enabled, the setting is lower than that of the
combined ambient lighting glare on the screen and characteristics of the LCD panel with
the current Brightness setting.
In either case, increase the Black Level control level to a point where the warning icon
disappears, which indicates the display can achieve the current Black Level value, or set
the control to 0.0 cd to select the lowest possible Black Level.

13 | MULTIPROFILER - USER’S GUIDE
Reset
Clicking the Reset button will restore the default Picture Mode settings for the currently selected Picture
Mode.
Ambient Light Compensation
Selecting the Ambient Light Compensation will enable the ambient light sensor located on the front of the
monitor. If enabled, the current measured ambient light level will be used to calculate the Black Level of the
monitor. See the previous section on Black Level for more details.
Response Improve
Selecting the Response Improve setting helps reduce blurring that can occur in fast-moving images.
Metamerism correction
Selecting the Metamerism correction setting can improve the white point color matching when the monitor
is used side-by-side with a standard color gamut monitor. This feature compensates for the way the human
eye perceives colors slightly differently compared to the scientic instrument used to adjust the monitor during
calibration. This difference is due to the different spectrum of light that makes up the screen image on the wide
color gamut compared to that of a standard color gamut monitor.

14 | MULTIPROFILER - USER’S GUIDE
PIP panel
The PIP panel controls the settings for the Picture-
In-Picture feature on the monitor.
The PIP window feature allows:
• Two different video inputs to be viewed
simultaneously. For example, if you have two PCs
connected to the monitor, you can view the video
from both at the same time.
• Two different Picture Modes to be viewed
simultaneously with either the same or different
video inputs. For example, if you want to view and
compare the current screen image as if it were
displayed on an sRGB gamut monitor.
• A Color Vision Emulation to be applied. This
is useful for viewing how the screen image will
be perceived by someone with a color vision
deciency.
The PIP mode can be congured as follows:
• Off - Turns off the PIP function.
• PIP (Picture-In-Picture) - The secondary picture appears inside the main screen area. The size and
position of the picture window can be changed using the Horizontal and Vertical Position controls.
• PBP Full (Picture-By-Picture) - The secondary picture appears to the left of the main screen area
and the main screen is sized to half of the entire screen area. Both screen images are scaled to t the
each half of the screen. If the monitor is rotated into portrait orientation, the screen images will be shown
at the top and bottom of the screen.
• PBP Aspect (Picture-By-Picture) - The secondary picture appears next to the main screen area
and the main screen is sized to half of the entire screen area. The aspect ratio of both screen images
are maintained from their original.
Video Input is used to select the video input to be shown on the PIP window. A red arrow in the list indicates the
current video input for the main screen. Using this function it possible to view video from two different sources
simultaneously.
Picture Mode selects the Picture Mode to be applied on the PIP window. The red arrow in the list indicates the
current Picture Mode used on the main screen. This function makes it possible to view the PIP or PBP window
in a different colorspace.
Horizontal and Vertical Position - these controls adjust the location of the PIP window on the main screen.
Color Vision Emulation - this control selects the type of color vision deciency emulation that is applied to the
PIP window. Using this function in a PIP or PBP allows simultaneous viewing of the normal and color vision
deciency emulation versions of the same image. See the following section for a more detailed description of
this function.
Note 1: MultiProler sets the ICC/ColorSync prole for the main screen and not the PIP window. Therefore
some color-managed applications may not display as expected in the PIP window because the ICC/ColorSync
prole for the main screen is being used.

15 | MULTIPROFILER - USER’S GUIDE
Color Vision panel
The Color Vision panel controls the Color Vision
Emulation settings used to emulate several modes
of color vision deciency, also known as color
blindness.
This function can be used to help determine how
people with such deciencies will perceive colors.
As an example, this feature is useful when designing
a user interface that relies on color for differentiation,
in order to make sure that someone with a color
vision deciency can adequately perceive the color
differences.
Click the corresponding selection to activate the
different emulation modes.
The monitor can emulate color vision dichromacy types:
• P (Protanopia)
• D (Deutanopia)
• T (Tritanopia)
Additionally a Grayscale mode can be used for evaluating contrast legibility.
Note 2: Dual 3D LUT limitation - The MultiSync PA Series SpectraView Engine is limited to using one set of 3D
LUTs at a time. This means that the PIP feature can not be used to correctly show a Picture Mode that uses a
3D LUT at the same time that a 3D LUT Picture Mode is used on the main screen. 3D LUTs are only used for
the Custom Picture Modes created for Print Emulation.

16 | MULTIPROFILER - USER’S GUIDE
Settings panel
The Settings panel controls some of the monitor
features.
The Power LED Indicator controls can be used to
change the color of the LED between blue and green,
and also adjust the LED brightness. For example, the
LED brightness can be reduced as necessary in dim
environments if it is distracting.
The Digital Uniformity Correction control adjusts
the screen uniformity correction applied to the monitor
in order to improve the screen luminance and color
uniformity.
This compensation is done at the expense of some
screen brightness. A higher level of correction will give
a more uniform screen, but the maximum brightness
that can be achieved will be lower.
Selecting Show White Screen will display a white test
pattern over the entire screen area. Use this pattern
to easily judge the impact of the Digital Uniformity
Correction level on the uniformity or evenness of the
screen.
See the following section for a more detailed description of how the Digital Uniformity Correction feature
works.
When Automatically create and manage ICC display proles is selected, MultiProler will create an ICC/
ColorSync prole for the current Picture Mode, and automatically register it with the Color Management System
whenever the Picture Mode is changed. Deselect this to prevent MultiProler from automatically changing the
ICC/ColorSync prole for the display.
Storage Location ( Mac OS only) - species where the generated ICC/ColorSync proles are stored. Options
are:
• Per User of this computer - the prole is stored in the User’s prole folder. Proles in this folder are
typically not accessible from other user accounts.
• Shared by all users of this computer - the prole is stored in the shared prole folder that is
accessible by all user accounts.

17 | MULTIPROFILER - USER’S GUIDE
About Digital Uniformity Correction
Every LCD panel will have some form of color and luminance non-uniformity across the screen. Even
though the panel used in the monitor has been carefully selected and sorted during production,
there will be some remaining non-uniformity. To reduce the impact of this, each NEC MultiSync PA
Series monitor is individually measured and characterized during production to map areas of non-
uniformity. This data is then used to build an internal three-dimensional correction table and stored
in the display. Screen non-uniformity is signicantly reduced when this correction is applied using the
Digital Uniformity Correction circuit.
This circuit works by reducing the luminance levels of areas of the screen that are brighter than oth-
ers. This is done for red, green, and blue so that uniform color as well as brightness is achieved. As a
consequence of this correction, the maximum brightness or luminance from the display is reduced
when this feature is used. The level of Digital Uniformity Correction that is applied to the display can
be controlled using the Correction Level control and should be set to a level that gives the best bal-
ance of uniformity versus brightness reduction.
The PA Series will intelligently adapt the level of Digital Uniformity Correction as the Brightness
control is changed. If a Brightness level higher than that which can be achieved with the current Digi-
tal Uniformity Correction level is selected, then the correction level will be reduced in order to best
achieve the selected Brightness. A warning icon will be shown next to the Brightness control in this
case to indicate that the level of Digital Uniformity Correction has been reduced due to the current
Brightness setting.

18 | MULTIPROFILER - USER’S GUIDE
USB panel
The USB panel controls the DisplaySync Pro
settings.
MultiProler allows the mapping relationship of the
two upstream (inputs) USB ports to the video inputs
to be congured.
The current video input is indicated by a red arrow.
In the example shown on the left, the current video
input, DVI-2, will select upstream port USB1. When
the video input is changed to the D-SUB (VGA)
input, the upstream port USB2 will be selected and
all connected USB devices will be switched over.
The setting can also be used to immediately switch
the upstream USB port for the current video input.
This is useful, for example, when you want to change
the connected USB devices between two host PCs
without changing the video input.
Note: The USB upstream port assignment is not updated until the current video input is changed. To
immediately change the USB upstream port, hold down the INPUT button on the front of the monitor
until the shortcut menu appears, then select the USB port.
About DisplaySync Pro
The NEC MultiSync PA Series displays feature an integrated USB 2.0 hub with 3 downstream (outputs)
and dual upstream (input) USB ports.
The dual upstream USB ports allows the integrated USB hub to switch between two dierent host
PCs. Devices connected to the USB outputs on the monitor will be switched between the two up-
stream ports. This switching can be linked to the video input selection on the monitor so that as the
video input is switched from one host PC to the other, any USB devices connected to the monitor,
such as a keyboard and mouse, will also be switched along with the video.
This feature allows the monitor to function as a KVM (Keyboard Video Mouse) switch. The INPUT
button on the front of the monitor can be used to quickly switch between dierent video inputs. The
attached USB devices will follow the current video input selection.
Note: Once devices are switched to another host PC, they will no longer be accessible on the original
PC until the input is switched back.
Important: Extreme care should be taken when using the DisplaySync Pro with certain USB de-
vices such as ash memory sticks and hard drives, as data can be lost or corrupted if the device is
switched between upstream ports while write operations are being performed. Always use the device
“eject” function on the host PC before switching upstream ports with these types of devices.

19 | MULTIPROFILER - USER’S GUIDE
Status panel
The Status panel shows various aspects of the current
software and connected monitor.
Software Version shows the version information for
the MultiProler software.
The Check for Software Updates button will directly
query the NEC website to see if a newer version of the
software is available. If a newer version is available,
a message will be shown listing the new version, and
a link to download. This function requires an Internet
connection and many not function if a proxy setting is
being used on the system, or if a rewall or security
application blocks network access from MultiProler.
The Re-Synchronize Color Settings button will query
the Picture Mode settings on the monitor to make sure
that the modes listed in MultiProler reect those of the
monitor. During this process, the screen will ash and
change color for approximately 30 seconds.
For example, if the monitor was manually adjusted
using the On Screen Display controls, then the monitor
settings may become out of sync with those shown
in MultiProler. In this case, use this feature to re-
synchronize the MultiProler settings.

About Picture Modes
The NEC MultiSync PA Series feature 5 selectable Picture Modes which can be individually congured to different
color settings. Picture Modes allow quick switching between different color settings, or when using the PIP (Picture-In-
Picture) or PBP (Picture-By-Picture) feature, to view two different picture mode settings simultaneously.
Each Picture Mode can be individually congured using MultiProler, and an ICC/ColorSync prole will be automatically
generated for the current picture mode as it is changed.
A Picture Mode species the color characteristics of the monitor. These color characteristics include:
• Brightness
• Black Level
• White Point
• Gamma Response
• Color Gamut
• Ambient Light Compensation, Response Improve, and Metamerism Correction Settings
The monitor has several preset modes which can be used directly, or modied as necessary. These presets are:
• sRGB
• AdobeRGB *
• DCI *
• REC-BT709
• DICOM **
• High Brightness
• Full
* not available on the MultiSync PA231W or P241W models.
** shown as DICOM Sim on the MultiSync PA231W model.
In addition to the preset modes, there are 3 or 5 (depending on the monitor model) special Custom Picture Modes which
can be fully customized and given a custom name of up to 13 characters. The custom name will be shown on the Picture
Mode selection buttons in MultiProler, and on the monitor’s OSD for easy identication and selection.
These Custom Picture Modes feature all of the congurable color characteristics listed above, and can also be used to
create modes that emulate the output of printers. Emulating the output of a printer requires a three-dimensional Look-
Up-Table (3D LUT) that modies the color response of the monitor to mimic that of the printer. MultiProler can create a
3D LUT of a particular printer by using an ICC/ColorSync prole of the device. See the Print Emulation section for more
information.
