Yes, it does have a filter. I have one and have used it with my NEC monitor using both the NEC Spectraview and Argyll software to calibrate. I get pretty much the same results with either software approach.

It does come with some color correction files (.edr which can be converted to argyll .ccss) for different types of LCD monitors (CCFL vs. LED, standard vs .wide gamut). But even these do not seem to be very NEC specific. Bolek
