I use 2 x30" screens dual mode, and I dont get into a position where it would be an issue, but then I strictly use it for editing.
So I see the red mesh(NEC?) extending further out of the solid blue area. This indicating a larger vomue(I take it), and where is the Eizo?
I wonder how my XL30 falls into this? I purchased it knowing it is larger than ADOBE RGB
Eizo is the colored shape.
In simple words - Eizo and NEC have similar green colorant, but NEC has blue and red colorants, that are more saturated:
XL30 with RGB LED backlight is even larger, there's no ICC profile on Samsung nor LaCie website, so I can't add it to my comparison.
Problem with S-PVA is that it gradually changes the contrast when you change the angle of observation:

As a result - when you edit a picture on a 30" S-PVA, the lateral part of the image may have slightly brighter shadows, than in the center.
