About MultiProfiler

MultiProfiler is designed as a companion to NEC MultiSync monitors that feature the powerful and sophisticated SpectraView Engine; such as the P and PA Series desktop displays as well as several large-screen displays (please see Supported Display Monitors). This software provides complete control of the SpectraView Engine in an easy-to-use application.

SpectraView Engine equipped MultiSync monitors utilize this sophisticated processor, combined with internal luminance, temperature, and time monitoring, and individual characterization and calibration of each unit during production, to provide an unparalleled level of color control, accuracy and stability.

The high-contrast LCD panel used on the monitor, coupled with the SpectraView Engine, provide the utmost in versatility such as the ability to accurately emulate colorspaces like AdobeRGB and sRGB.

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

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 supported 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:
