ReadMe Information for Mac OS X
Version 1.2.00 - build 130904 - September 4 2013
MultiProfiler is designed as a companion to NEC MultiSync PA and new P
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
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 Profiles and internal 3D Look Up
MultiProfiler uses a two-way communications link with the
display monitor to perform adjustments. Two different methods of communications
1. DDC/CI (Display Data Channel - Command Interface) -
Communicates via the video graphics adapter and normal video cable. No extra
cables are necessary. Support is required in the video graphics display
driver in order to provide this functionality. This communications link is an industry standard developed by
VESA (Video Electronics Standards
2. USB (Universal Serial Bus) - Communicates with the
display via a USB connection from the host PC. A USB cable (not supplied) must be connected
between the Mac and one of the upstream USB ports on the display. The
display will also function as a USB hub.
MultiProfiler will automatically default to using the USB
connection if detected. The Display listbox will show the model name of the
display followed by "(USB)" when the USB connection is being used.
New Display Firmware
New firmware for the following display models is available which adds some functionality improvements.
Navigate to the following page for more information:
Mac OS 10.7.5 and Mac OS 10.8.0 - 10.8.2 - "No Communications" with Nvidia based graphics
- A "No Communications" error may appear when using MultiProfiler on the above versions of Mac OS with Nvidia based graphics. Connect a USB cable between the Mac and one of the USB inputs (upstream ports) on the display. This issue is fixed in Mac OS 10.8.3 and higher.
Mac OS 10.7 and higher - "ICC Profile - Storage Location" is disabled
- Mac OS 10.7 no longer allows users to store "shared" ColorSync profiles in the system folders. Therefore the Preferences option to set the ICC Profile storage location is disabled, and "Per user of this computer" will always be used.
- This version of MultiProfiler supports
communicating with the display via USB. Connect a USB cable (not supplied)
between the Mac and one of the USB inputs (upstream ports) on the display. Make
sure the correct USB input is selected on the OSD. MultiProfiler will
automatically select the USB connection instead of DDC/CI when the USB
connection is detected.
- If using the PA271W, PA272W, PA301W or PA302W with the Apple mini DisplayPort to
DualLink DVI adapter, a USB connection to the display should be used due to
communications compatibility issues with this adapter.
MultiSync PA231W, P232W, P241W and P242W:
- The color gamut of the display is not wide color gamut, and is 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 MultiProfiler will allow the Picture Mode settings to be modified 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.
MultiSync PA231W, P232W and P242W:
The 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 MultiProfiler.
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.
No communications or communications
error when using a DisplayPort video connection:
- This version of MultiProfiler requires Mac OS X
version 10.5 or higher.
- This version of MultiProfiler is a Universal
Binary and supports both PowerPC and Intel based Macs.
- When using an optional USB connection to the display for
communications (instead of using DDC/CI), MultiProfiler does not depend on the
video graphics adapter and therefore the following compatibility issues do
not apply. If you experience a compatibility issue it is recommended to use
a USB cable to the display for communications.
The following compatibility issues only apply when using
DDC/CI to communicate with the display (i.e. there is no USB cable from the Mac
to the display):
- The following Apple Macs require Mac OS
10.5.2 or higher in order to use MultiProfiler . MultiProfiler not
compatible with these Macs using earlier versions of Mac OS due to
issues with the video chipsets and drivers:
- Intel based Macs using Intel graphics
- Intel Mac mini
- 13" MacBook with Intel GMA X3100
- 17" iMac with Intel GMA 950 graphics
- Second generation MacBook Pro 15" and 17"
that have NVIDIA GeForce 8600M GT graphics chipsets.
This issue is due to a hardware
incompatibility with the Intel GMA X3100 graphics processor and can
not be fixed by a future software update. Note that these monitors
will otherwise function normally on these models of Apple Macs.
- Mac OS 10.5.6 prevents MultiProfiler from
being able to communicate with the display monitor on PPC based Macs. Customers
should update to Mac OS
10.5.7 or higher to avoid this issue.
- The 13-inch MacBook, and 15-inch
and 17-inch MacBook Pros
with Mini DisplayPort video outputs released by Apple in October
2008 and January 2009 require Mac OS 10.5.7 in order to work with SpectraView
using the DisplayPort to SingleLink DVI adapter from Apple. MultiProfiler will not
be able to communicate with the display monitor when using Mac OS 10.5.6 and earlier on these
The DisplayPort to DualLink DVI adapter required to run the LCD PA271W, or PA301W when using a DVI video input is not yet compatible with MultiProfiler. Use a USB connection for communications in this case, or connect the display via DisplayPort instead of DVI.
- MacPro with Nvidia GT120 may not correctly detect the display is using Mac OS 10.5. Upgrading to Mac OS 10.6 may be necessary.
MultiProfiler supports the following NEC display
- NEC P232W
- NEC P241W
- NEC P242W
- NEC PA231W
- NEC PA241W
- NEC PA242W
- NEC PA271W
- NEC PA272W
- NEC PA301W
- NEC PA302W
- NEC MD301C4

"No Communications" or "Unable to communicate with
- Confirm that DDC/CI is set to "ENABLED" on Tab 8 of the
Advanced On Screen Display controls.
- If using a MacBook, look in the System Preferences - Power Saver panel for a setting to select the graphics performance vs. battery life. Try selecting the opposite setting and restarting.
- Connect a USB cable (not supplied) between the Mac
and one of the USB inputs (upstream ports) on the display. Make sure the
correct USB input is selected on the OSD. MultiProfiler will automatically
select the USB connection instead of DDC/CI when the USB connection is
- Confirm that a USB 2.0 compatible cable is connected between the Mac and the display (if using USB).
- If possible try using a DVI connection instead
