The HP / X-Rite DreamColor APS colorimeter (an OEM device) is a perfect
example of this issue. The custom colorimeter is appropriately matched to
the very well designed DreamColor display, but *only* the bundled
DreamColor software can communicate with the colorimeter or the display.
In addition, the bundled software will not allow the use of the EyeOne Pro
spectro or any other appropriate measurement device.
That is the nature of a custom solution to monitor profiling. I don't
remember anyone complaining about the custom colorimeter and software of the
Sony Artisan? Indeed, it was usually praised.
Therefore, the only way to calibrate the monitor is with the proprietary
colorimeter and bundled software.
I haven't got one of these monitors, so I can't be sure, but I would be
surprised if you can't use your i1pro spectro or an i1 Display with the free
iMatch? But if you want hardware calibration, then you have to use software
customised to the hardware. If I want hardware calibration of my Eizo's, I
have to use Eizo's software or Basiccolor with a limited number of
colorimeters/spectros. But I knew that before I bought them.
Had I known the imposed limitations of the calibration and profiling
hardware and software,.....
Didn't HP publish details, or didn't you read them? I just found and read
Eizo's white paper on its built-in calibrator, since I was interested in
purchasing a monitor with one. That is probably the future, instead of
messing about dangling lumps of plastic/metal on the front of monitors, and
then running various programs to control them. The built-in calibrator even
recalibrates your monitor at night on a schedule, while your computer is
off - all automatically!
But that is not for you, since you can't move it to another monitor!
The recent announcements from the X-Rite folks on this list (Tom Lianza
and Steve Rankin) that X-Rite intends to allow developer access to the
**retail** version of the I1 Display Pro III is welcome news, as was the
comment from Karl Koch that the DISCUS will allow third-party software
development. Both are big wins for consumers who care about accurate
color.
But as Karl Lang pointed out, a cheap colorimeter, customised to the
specific primaries of the monitor can out-perform GP colorimeters and rival
the $10-20,000 lab colorimeters (like the Discus?) and spectroradiometers:-
"I have worked with colorimeters that cost less than $100 to build that
rival the accuracy of a $20,000 spectroradiometer when used on the display
they were designed for. That same spectroradiometer could not provide any
measurement of black on the display. The $100 colorimeter could measure
black with a high degree of accuracy." -

Methinks you protest too much. You think I defend too much. C'est la vie!
