Just about every user with 3D LUT capable Eizo's have successfully calibrated their displays.
(Actually, I know of no-one that has failed to do so.)
But, there are issue with some models and the location of the iTPG, which means it cannot be used to verify the LUT on such models.
(Plus the issue with the LUT location before/after YUV conversion on some models.)
I have just realised the info on which models have the iTPG in the wrong place is not showing on the User Guide.
I'll sort that now.
And the 'Extended' LUT info makes no mention of 'range', as it has nothing to do with signal range.
It is just the terminology Eizo use to define the two different LUT options.
Standard, and Extended.
