The new PA series of NEC SpectraView’s can emulate sRGB or operate as wide gamut displays; best of both worlds. All the applications you mention are color managed and will take advantage of the wider gamut display assuming a good display profile (which with the SpectraView II software or the free Multiprofiler software is doable).
Depending on the press profile, there are colors that fall outside sRGB gamut!
While the best of both worlds is nice, we don't want to spend the premium on getting the extended color space if we don't really need it.
You need it in terms of seeing colors in CMYK output space that exceed sRGB. Unless not seeing those colors isn’t important to you ...
For similar pricing, Eizo has a series of Flexscan monitors that appear to have an edge or two over the NEC's, at least looking at specs. Since Eizo is the monitor supplier of choice for color management (so I am told by color management consultants!) why do you prefer the NEC?
On anther front, I do a lot of gray scle work and the monitor has to also do that well, separating the values between zones 1,2 and 3 decisively. Again, Eizo does verywell, although I may have to consider the ColorEdge versions ($$$$!). How does NEC stack up here?
