Hi, Ok, here are some notes about EyeOne and the monitor profiler.
Right now, beta 3 does ONLY support EyeOne display. I have also a patch for the "normal" EyeOne, which is a spectrophotometer and a lot more expensive. Images of both devices in the profiler page here: http://www.littlecms.com/profiler_qs.htm. So, if anybody is interested on using this device (EyeOne) please contact me or wait until beta 4. The monitor profiler does work reasonably well on CRT. For TFT is not working, still needs a few debugging. I will try to add support for TFT in my (rare) spare time. For CRT and EyeOne display, is working quite well. I made a profile for a LaCie electron22blueIV and then checked about 400 additional patches. Mean dE is still about 1, and the maximum does not exceed 6, which seem reasonable. Again, if anybody is interested on doing similar testing please contact me. There are, however, differences in the profiles created by lcms profiler and those created by EyeOne software. Perhaps the most important is the white point. Yes, I also noticed Gretag software is using D50 always. This is not important unless you plan to use absolute colorimetric intent. In such case the profile does need the white point to recover absolute values. Another difference is the use by Gretag profile of a special tag called 'vcgt' (which stands for 'video card gamma tag' ) Profiles using that does need a loader, and modifies the hardware gamma ramps. I am trying to avoid this entirely on all lcms library and tools, since that affects ALL applications, and not only those explicitly color-managed. Please note this is NOT in any way a criticism to Gretag profiles, they does work and are accurate. I'm just offering an alternative from a different point of view. Finally, the lcms profiler does NOT set the profile as default nor touch anything of your windows configuration. It only saves a profile in the color folder and then uses this profile for its own business. If you want to use the profile in any other application (Photoshop, for example) you must associate the profile to your display manually. This is done by right-clicking the desktop and selecting "Properties-settings-advanced-Color management". To know the name of the profile, in the profiler, select Imaging options-Monitor advanced. Sounds a bit complex, sorry, beta 4 will make things a bit easier.
