As NEC is using BasicColor software in Europe, I could only surmise that between the two companies they have tested it all for proper DDC compliance and it works - hard to sell a display as a "Reference" model (and charge more money for it) if they haven't. Regardless of all that, the proof of the pudding is in the tasting. I've tasted both and I kept BasicColor. Just somewhat better in my experience, and BTW, very useful operating instructions.
