Let's try together make complete list of wide gamut display models. Try to begin: 1. Dell UltraSharp U2410 2. NEC 2490Wuxi2 and NEC 2690Wuxi2 3. HP LP2475w Sorry for my english.Is the correction matrix not a result of particular colorimeter's deviations and the specific RGB output of a particular monitor, so not universal enough to use the ccmx for another set of both devices, the monitor being the more consistent one? I recall a discussion like that in this forum.
Yes, that's the problem with most colorimeters, the inter-instrument variability seems pretty high (with the exception of maybe the DTP94 and the new X-Rite devices, which I heard are pretty good in that regard). Averaging of several correction matrices for one particular display/instrument combination could probably help reduce that problem a bit.
For download there is a small list of ccmx files here with similar comments about their usability: http://argyllcms.com/doc/ccmxs.html
