I hope that my question is appropriate for this forum. I plan to purchase an NEC P221W monitor for post processing. Although NEC offers their SpectraView II hardware/software bundle to calibrate this wide-gamut monitor, I would prefer to have a colorimeter that I could use on my other monitors as well. Has anyone used a 3rd-party unit (e.g. the i1Display2 or the Spyder3) to accurately calibrate the P221W? If so, is it preferable to use the puck w/ NEC's SpectraView II software? Thank you so much for your help.
