Gamut is great. Uniformity on my samples is not ok, because it
actually has cyan/magenta zoning.
The image shown here has been saturated, but the zoning is apparent to
the naked eye, and creates the effect of a color cast.
I am aksing Chromix to swap this sample of the monitor, as I assume
that a professional display should not have color uniformity issues,
and don't believe that profiling can fix this. If someone here has a
comment, I'd be delighted to hear it.
I have similar issues with my HP DreamColor. I did not respond earlier
as I hoped the display would pick back up from it's jet lag and the
exertions of the long[1] and dangerous[2] journey from Seattle to
Germany -- but it didn't as yet :-(
I see a yellowish spot (looks like an old bruise, approx. 3 inch in
diameter) and two larger, magenatish zones. I measured the color
difference between the yellow and one of the magenta spots (average of
10 measurements per spot) and got Delta E = 7.9 on what should be a
uniform, light gray [3].
Does anyone know HP's production tolerances for uniformity? I guess
(hope!) DE 7.9 is above and ask myself wheater it's a damage in transit,
a glitch in HP's quality check or a widespread failure.

Even the silver clingwrap that should protect the display was damaged:
