Hi Scott,
I have a dead Eye-One Display with the same problem you described below.
I believe is a failure in the green sensor. An easy way to detect this
kind of problem is look at the triangle gamut in the CIE "horseshoe"
diagram. If the triangle is "short" in the greens, there's the green
problem!
Best regards,
Lorenzo

Our internal testing using DTP94s and EyeOnes interchangeably has

Keep and eye on those EyeOneDisplays. I have seen about 8 of them go
bad over time. Sometimes they go horribly bad overnight and sometimes
it happens slowly. A magenta cast in a display's calibrated whitepoint
is the sign to look for.
I prefer to LOOK at images.
Me too - that's always the bottom line that maters more than anything
else. I have come to recognize certain trends in CEDP's validation
results that translate into positive or negative viewing conditions.
Same with MP's round trip numbers. After a while you come to recognize
certain trends and get a "feel" for the results. So for me, there is
some value.
As for colorimeters I have found the EyeOne Display (1and2) and
Spyder1 to be inconsistent
How many samples of each, based on what, over what time span?
Over 100 EyeOneDisplays and a few dozen Spyders since they were
introduced. Although I own several of each I have an extensive client
base whose devices I also use and compare to my own when I am onsite
(which is 4-6 days a week). EyeOne Displays are pretty consistent with
each other when they are in good but a small percentage are bad out of
the box and some go bad over time. I have not yet seen a bad DTP94.
