About MultiProfiler

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 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 Profiles and internal 3D Look Up Tables.

MultiProfiler uses a two-way communications link with the display monitor to perform adjustments. Two different methods of communications are possible:

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 Association).

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.

Supported Operating Systems and Macs

  • 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 processors:
      • Intel Mac mini
      • 13" MacBook with Intel GMA X3100 graphics processor
      • 17" iMac with Intel GMA 950 graphics processor
    • 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 machines.

    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.
