Guten abend Klaus,
I'm glad for you that HP has so promtply (schnell) supplied a replacement
panel *and* that this one is meeting your (well-deserved) expectations.

Interesting. I'm told by a very reputable, very large graphic arts company
(their name starts with a K), that they found this display not being uniform
enough to warrant a SWOP certification or support it in their software :(
Are you going to have some time (?) to quantify its uniformity? Maybe
something along the SWOP's new monitor requirents? See BabelColor's CT&A ISO
12646 targets here :
http://babelcolor.com/main_level/screen_shots/Spectral_Tools_ISO2.htm
Maybe the UDACT software also does this?

Much better? I would like to believe your subjective judgement, Klaus.
And it comes back to my above suggestion of using the ISO-12646 target to
quantify its uniformity in terms of luminance and chromaticities.
I'd be interested to compare with the Eizo CG21 I have here (I won't dare
show the figures for my Samsung...).

And every pixel is illuminated by its very own triplets of RGB LEDs? What
kind of Luminance are you calibrating it at? And have you got a custom
colorimeter and just a regular EyeOnePro? Have you tried it with Argyll?

Wunderbar!

As far as I know, the NVIDIA board will not support 10 bits? And that's
probably an OSX limitation? Do you have access to a PC? With one of those
Matrox 10 bits board? I think you would still be limited by Windows unless
you have special 10bits drivers.
Does the HP DreamColor accept a DisplayPort connection?
