Good evening Roger,

As we all know, HP has most likely hired X-Rite and Tom Lianza (or
some
other reputable lab) to tune the base EyeOneDisplayII colorimeter to
optimally respond to the spectral power distribution of the
LP2480zx RGB
primaries. Any "off-the-shelf" affordable instruments -- I'm talking
Spyder's, EyeOnePro's and the like -- in this context, couldn't
possibly do
as much justice to this monitor's colors as an instrument for which
the
colorimetric response has been specially tuned for this display.
That's the theory at least.
Yup - as far as hardware goes, a matched colorimeter would be ideal.
So, for ColorEyes Display Pro or basICcolor Display to "better" HP
on this
particular monitor, to give them a chance of being in the same
playing field
as HP, in my view, they'd have to have access to HP's customized
EyeOneDisplayII internals. Otherwise, the way I see it, they'd be at a
disadvantage relative to HP.
Hmmm... I'll have to think about this, and at the moment I'm jet-
lagged and tired to the bone. How did these companies get the specs
for the Display 2, or any other colorimeter? Can the essentials be
deduced empirically through testing? I've certainly been happier
with calibration / profiling using BasICColor on my Eizo CG 210 than
I am using Eizo's ColorNavigator, although Eizo certainly knows the
internals of the monitor better than ColorSolutions does. I'm not
sure how either company knows the internals of X-Rite's colorimeter.
When I first tried Match, it didn't talk to the monitor's hardware
LUT, so not surprisingly, the results were not great.
Assuming HP's color engineers use decent profiling and calibration
algorithms.
That's one potential "gotcha." I do like BasICColor's software, and
in particular their CIECAM02 implementation.
Incidently, I was told by a rather large graphic arts company that
they
wouldn't come up with a SWOP certification for this very monitor
because,
allegedly, its uniformity was not very good? I thought that was
hard to
swallow given the good reviews posted here by Ken and a few others.
But I
have to confess I have yet to see this monitor "in person".
I haven't seen any gross non-uniformity, but I'd be sending the
monitor back if I did. ;-) I haven't done any testing yet, and
probably won't until Wednesday. If what you say ends up being true,
and this company's decision is based on their experience with true
non-uniformity across the screen of sampled units, it will no doubt
be very disconcerting, to say the least.
Thanks for the comments and insight.
