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 must be connected between the host PC 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 available, when it is first run. To switch between USB and DDC/CI communication links, click the Display Configuration icon (next to the display list at the bottom of the main window), and then select the desired connection method from the list of monitors.

Using MultiProfiler

The MultiProfiler application is accessed from the Windows Start menu > NEC Display Solutions > MultiProfiler.

Supported Video Graphics Card Drivers

It is normally necessary to install the latest drivers for the video graphics adapter card. The video drivers included "in the box" with Windows will need to be updated with the full video driver packages available from the video graphics adapter card vendor.

Note: All PA series models and the P232W and P241W models feature using an optional USB connection to the display for communicating, instead of using DDC/CI. This can be used in cases where the video graphics adapter is not supported. A USB cable must be connected between the host PC and one of the upstream USB ports on the display. The display will also function as a USB hub.

Please refer to the following table for DDC/CI support:
