I have an EIZO S2231 (92% Adobe RGB). Here are my results:

All of my CM-Solutions give wrong values for color temperture. I don’t care about the number but use visual adjustment instead. But there is an important issue with the green, as Alex mentioned.
Please note that my result about the green are subjective.

EyeOneDisplay2 : CT is the best wrong, green value a bit too low.
Spyder3: CT is much too high, green seems to be ok.
DTP94: CT is much too low, green is much too high!

The CT for the native whitepoint of the monitor measured by Spyder3 and DTP differs more than 1000K!

I bought the DTP94 because of excellent tests, but in my opinion it is not ok that Quato sold the package as wide gamut suitable. It is for the high end quato monitors, because there is a wide gamut adjustment. Otherwise it is not suitable!

Recently there is a software update iColorDisplay 3.6.0, there is a generic wide gamut adjustment for S-PVA monitors. The CT is better, the green is much better. The green is 6% lower compared to the uncorrected version.

But I don’t rely on any solution any more. Highly precise instruments, good for nothing if they produce such errors on my monitor.

Please note these are my experiences, would be glad to hear of similar or better different results.

You basically have to try different colour temperatures until you get
one that works. Also in some software you can choose D65, for example, or 6500K and the two results would be slightly different. You could also try defining a whitepoint target as x y co-ordinates. Whatever your software lets you do. There is no easy answer, just trial and error.

A newer sensor like the EyeOne DIsplay 2 or Spyder 3 might also help but the DTP94 is still considered the best by many, it just doesn’t cope with wide gamuts as well.

I am in exactly in that boat — ColorEyes Display Pro + DTP94 on a wide gamut monitor (DELL 2408WFP). Calibration results in a greenish white point. Could you expand on that “fudge” workaround you are mentioning here? (in a comment or private email).
