I offer following CONCLUSION
[!--quoteo(post=0:date=:name=http://hoech.net/dispcalGUI/)--][div class=\'quotetop\']QUOTE (http://hoech.net/dispcalGUI/)[div class=\'quotemain\'][!--quotec--]A note about colorimeters, wide-gamut displays and dispcalGUI
Colorimeters need a correction matrix in hardware or software to obtain correct measurements from wide-gamut displays. The latter is currently not supported by dispcalGUI, so if you own a wide-gamut display and colorimeter which has not been specifically tuned for this display (i.e. contains a correction matrix in hardware), you will need a spectrometer to accurately measure such a screen.[/quote]
IMHO, that confirms, what Czornyj wrote and my findings, already mentioned earlier. There is one decisive factor. I'll paraphrase the above quoted Florian Hoech: When using a colorimeter with a wide gamut monitor, the device must have a correction matrix applied in hardware, as for the NEC custom mated i1d2 sensor, or applied through the software, like Quato's iColor Display 3. I don't now about the EIZO setup, but it guess ColorNavigator must apply a correction matrix, doesn't it?
This finally explains, why my wide gamut monitors
- do not work with a regular colorimeter, like the DTP94 or the i1 Display 2 (you might not notice this, as long as you have only one monitor, and the tint is not too strong, as the sensors seems to be consistently off between every characterization and profiling) combined with a software not applying a corrective matrix, like x-rites eye-one Match3 (don't tell me it works, just read the uncountable lamenting threads out there), BasICColor Display 4, or even SpectraView II and Argyll.
- but they do work with a software matrix filter like Quato's Display 3. (I don't know of any other. Do you?)
- I could not verify that it should be fine with the matrix filter mated hardware, like the NEC sensor (We are trying to buy one. Any cheap suggestions with overseas delivery?),
- or, as stated above, I could use a spectrometer, as a workaround, having all the disadvantages of the spectrometer measuring a display.
1 ) Why are they consistently off by the same different degree proper to each monitor?
2 ) Why is it that ( and I read this also in a number of desperate user comments ) after characterization, but before profiling the monitor always seems to look a lot better?
P.S.: Evidently, I agree with you, Steve, that changing the graphic card, the cables and connections, as well as cleaning up the drivers etc. is a prerequisite through which you have guided me with a lot of patience. And yes, I will get the new PA241 hopefully soon, because things are now maybe perfect in the world of Flexscan, but still I have not a good enough uniformity in brightness and chroma. It disturbs me and my colleagues here too much.
