NEC SpectraSensor can be used with ArgyllCMS + dispcalGUI, or basICColor display, so you can use it with other display as well. You can also buy NEC SpectraView II software, and X-Rite i1Display Pro sensor instead of SpectraSensor - i1Display Pro comes with decent i1Profiler software.
Multiprofiler can calibrate and profile NEC PA without sensor. It can also be used to modify calibration made with SVII, apply Ambient Light Compensation, Metameric correction, and 3DLUT simulation of a color space defined in a LUT type ICC profile.
Thanks for the quick reply! Do you know if the NEC's sensor can be used with other display? I thought it was a special version of another company's sensor and could only be used with an NEC display.
What's the benefit of the Multiprofiler software?
