I sold my Spyder3 bacause I found Eye One 2 colorimeter more accurate (..with Spyder3 every calibration - same parameters - gave sometimes very different results!!).
That was kind of my point above. "Accuracy" is only as good as the results. With the 324, the Eye-One Display 2 is as
inaccurate as the Monaco Optix XR. Can't say I've ever had the Spyder 3 produce different results, as you mention.
In emails with the creators of Color Eyes Pro, they explained that wide gamut monitors throw some colorimeters for a loop. They use a quite expensive color analyzer to get wavelength and
L*AB readings from test monitors. They then test various colorimeters to see how close they come to the original results. As the saturation goes up, some models tend to be "blinded" by the color being emitted, which then send incorrect data to the profiling software. That's how myself and others end up with pink or greenish grays. X-Rite notes the same effect in some of their help pages. The Eye-One and Optix XR work just fine with most monitors up to a certain point, but the sensors of the colorimeter then can't handle the higher end monitors. For me, the Spyder 3 is the only one that can correctly produce a gray for the 324 that matches a printing industry standard 5000K viewing booth.
Eye One 2 is used by all professional labs and all graphic monitors from excellent brand (NEC, Eizo, Lacie, Samsung)are precalibrated and tested with this colorimeter.
That may be so, but that doesn't mean they're the only choice. If it does what you need, great! But I'm much more interested in the results than what someone else is using. I have a Spyder 3, Eye-One Display 2 and Monaco Optix XR. For most monitors, I do use the Eye-One or XR with excellent results. For some monitors though, the Spyder 3 is the only one that works.
PRo PE is a great software with UGRA certification and excellent precision.
I'm very happy with the Color Eyes Pro software, but am always willing to try other software to check it out.
Supposedly, X-Rite is working on a new colorimeter to replace the Eye-One Display2. The reason being is that they know it's outdated for the newer wide gamut monitors. X-Rite also now owns both the former Monaco Profiler and Gretag-MacBeth Profile Maker software. I have the first, and it hasn't been updated for at least 2 years. Profile Maker hasn't seen much action either. A customer service person at X-Rite told me they were working on a new product that will combine the best of both packages into a new product. She just had no information when we might see it.
