Hi,just looked at some of the profiles, and the first thing I thought was "wow, is the gamut of that display limited" :) (way smaller than even sRGB, I've seen that on alot of TN panel displays, mostly Laptop/Notebook screens) - but I think that's maybe another issue altogether.
Regarding the green cast problem, how do you view the images (e.g. which OS, viewer application and setup)?
Also, just out of interest, why no dispcal (as mentioned in your other message)?

It's because most of consumer colorimeter have far not exact spectral sensitivity as in described in CIE standard for standard observer. The correction matrix are applied to colorimeter data for every kind of display type in software (LCD CCFL, LCD LED, Wide GAMUT LCD, Projectors). If Your kind of display wasn't corrected by matrix by manufacturer, the results may be quite far from wanted.Does this correction happen in hardware? Anyway I though the Huey was a stupid device... As in just a passive sensor... Since it has no firmware...And it _does_ work with single shaper matrix profiles.Yes, It may work because of very restricted fitting capabilities of single shaper matrix. In general, there are rotary dispersion effect in the subpixels of LCD. The light spectrum, which passes through a liquid crysrals, are depend of crystals rotation angle. The effect is more distinctive at a maximum subpixel transparency level. So the averaged by gamut volume shaper data may not to be greenish, but fitted LUT data in certain transparencies levels can. Do You try a shaper matrix, not a single shaper?I've uploaded some sample files here: http://files.pcode.nl/test/argyll_greencast.zip It's the original ti3, all the generated profiles, the profiles are named as the options used for colprof. I also converted some JPEGs using jpegicc from lcms... Please note that only the single shaper matrix profile looks good on my screen... Even the multiple shaper matrix looks a bit greenish.. I'd appreciate any pointers to what might be the issue... Regards, Pascal de Bruijn
