Interesting thread, (and timely). I just used my i1 display
yesterday (for the first time in maybe a year, what can I say) and
after applying the resulting profile, the monitor became quite
"purple" with a highly posterized appearance. So I have no idea if
this snuck up on me or not, TBO I do not use this monitor for color
correction.
I tried expert and basic modes within Eye-One Match, large and
small profiles, all gave same result. This is on an iMac G5,
10.5.8. Manually creating a profile using the os/ expert options
worked as usual, however I had to move several of the adjustment
sliders to the extreme limit of their travel to successfully get
thru the process, which was unusual. The result onscreen looks
completely normal, as far as I can tell, for casual use.
When looking at the resulting profile, the "Apple Display Video Card
Table" of this most recent profile (created manually) has a strong S-
shaped curve, again, pretty unusual. I checked older profiles I had
created manually and they exhibited a more normal curve, similar to
the OEM profile.
The profile created by the i1 Display has an "Apple Video Card
Table" curve that looks like a seismograph.. sharp angles, very
jagged.... it really is kind of humorous. I guess that would
explain the posterizing.
Since my manually-created profile was kind of an eyebrow-raiser
anyhow, I suspect that the video card is starting to get a bit
funky, and its behavior falls outside of the i1/ software's ability
to compensate.
I just installed Eye-One Match on the iMac G4 in the next room, used
the i1 display, and it worked perfectly. Hmm.
