Here are the results of dispcal -r using the Huey that came with it and
my Eye-One-Pro.   I wasn't sure how to place the Huey.  I put in so it
seemed entirely within the test window and I ran a length of tape on the
bottom of the Huey to the frame to try to keep it flat on the screen.
Here is what I got



Huey:



White    Correlated Color Temperature = 10922K, DE to locus = 12.4
White Correlated Daylight Temperature = 10923K, DE to locus =  9.7
White        Visual Color Temperature = 9095K, DE to locus = 11.6
White     Visual Daylight Temperature = 9518K, DE to locus =  9.1



Eye One Pro



White    Correlated Color Temperature = 6875K, DE to locus = 11.5
White Correlated Daylight Temperature = 6867K, DE to locus =  8.5
White        Visual Color Temperature = 6383K, DE to locus = 11.1
White     Visual Daylight Temperature = 6528K, DE to locus =  8.1


Assuming that the display white point really is close to 65K, one way
of interpreting this is that the Huey has significant colorimetric
errors on this LED display, that the software that it is bundled with
compensates for.
