I have checked my i1D3 (ColorMunki Display) on another display and versus
another colorimeter. The display is a Dell 2209WA (standard gamut CCFL)
calibrated in May 2012 with Spyder2, D65 white point, sRGB gamma, 120 cd/m2.
Today I measured the display response with both Spyder2 and i1D3. Similar to my
previous comparison:
* The i1D3 is reading a lower white level, -11 cd/m2.
* The i1D3 is reading a higher colour temperature, +300 K.
And yes, the Spyder2 reports an elevated black level (which is why I bought a
new colorimeter).
It seems the i1D3 is the odd one out. Maybe I should contact X-Rite?

Here are the measurements:
Spyder 2
--------
C:\Users\Wag\Documents\Stephen\Argyll>dispcal -y l -r -P 0.5,0.5,2.0
Place instrument on test window.
Hit Esc or Q to give up, any other key to continue:
Current calibration response:
Black level = 0.42 cd/m^2
White level = 117.49 cd/m^2
Aprox. gamma = 2.03
Contrast ratio = 277:1
White chromaticity coordinates 0.3098, 0.3329
White Correlated Color Temperature = 6627K, DE 2K to locus = 8.6
White Correlated Daylight Temperature = 6624K, DE 2K to locus = 4.9
White Visual Color Temperature = 6297K, DE 2K to locus = 8.3
White Visual Daylight Temperature = 6448K, DE 2K to locus = 4.7
The instrument can be removed from the screen.
