On his blog, he has reported on his testing of an NEC 2690WUXI. Before he received it, he was very enthusiastic about its specs and thought it might be the be-all, end-all of monitors. His conclusion was that while it measures a wider gamut, in the real world, it makes little or no difference.
Well I can tell you I have all kinds of images that fall outside of sRGB.
I can tell you his testing methods are not the same as Karl's! If he's using 900 samples and a $20K Spectroradiometer to make these conclusions, we should get him and Karl to talk.
The NEC 2490 (sRGB) unit scored even higher in Karl's tests. Maybe he needs that unit. But for those that do need a wider gamut display, this one is hard to beat.
