Here are mine Spectraview II values.
Spyder 3: CIE 0.306, 0.338 at 114.24 cd/m˛
i1 Pro: CIE 0.313, 0.335 at 116.63 cd/m˛
i1 Display Pro: CIE 0.313, 0.330 at 114.33 cd/m˛
What did you do to see 4 decimal places?
I generally get extremely close readings from my custom NEC i1D2 and my i1Pro when using SV II to measure my NE PA241W. Over a year they don't agree quite as much at the start (when most values would be exactly the same to .000 or .001 off, I think only one or two had been .002 off) but even now it's pretty close.
I did find that I had to let the NEC i1D2 warm up for a long time, 15 minutes was NOT enough for it to closely match my i1pro. I let it warm for 45 minutes and then, with the monitor in native gamut mode/photo editing, measured:
WP .313,.330 6503K
R .679, .309
G .214, .690
B .152, .056
and the custom NEC i1D2 (and I believe they DO custom calibrate each copy, they have implied that, and I'd have to be awfully luck to have such close matching I think, and the price for them would be a remarkable rip-off otherwise and the difference between stock i1D2 and their i1D2 is the same as many place charge for a custom calibration):
WP .315, .330 6376K
R .683, .306
G .214, .691
B .152, .057
and comparing sRGB emulation mode:
.152 , .061
whle i1d2 said:
so the differences have certainly grown over the past year, when both were new, as I said, many values were .000 and the rest .001 but for a couple at .002 while nwo there are a number of .003 differences and one .004, that said there are still many .000 or .001 so the match is not too far off
In fact, it's actually only how each reads red where any difference at all lies and that is where the difference increased a little bit over teh year. For how each reads the blue and green signal, it's essentially exactly the same for both and still so a year a later.
I didn't compare luminance or gamma tracking. I didn't compare black point since the i1pro is sketchy there and tends to return a different luminance, often quite different, on every reading from SV II since it doesn't average them much.
(side note: I think when comparing probes and seeing how they do on wide gamuts, in particular, the chromaticities need to be measured and not jsut luminance and white point! For some probes it is the primaries where the measurements go really crazy on wide gamut too and not just with the WP.)
