Spectraview II calibrates following Nec panels:
1980SXi, 1980FXi, 1990SX, 1990SXi, 1990SXp, 2090UXi, 2180UX, 2180WG-LED (Reference 21), 2190UXi, 2190UXp, 2490WUXi, 2690WUXi
It doesn't matter if it's Spectraview, or Multisync version. In US there's no Spectraview version at all. For example - I calibrate my "normal" Multisync 2190UXi with SV II without any problem. I also calibrated my friend's Multisync 2690WUXi with the same result.
You also don't have to pay for a nonsense PE version, that is just a normal Multisync with Eye-One colorimeter included.
2470WNX is just an usual 8 bit panel, without the posibility of any hardware calibraton
