I am told that HP is now researching the cause and extent of the
uniformity issue with the LP2480zx. HP indicated that they will keep
us posted. Meanwhile, if anyone else is experiencing what has been
described by Klaus and Edmund, HP would like to hear about it and
possibly offer a replacement if warranted:

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:
