Have one. Won't comment on color calibration since I am not a photographer. Compared to my Nec PA 271W, I would say it has more punch but maybe a bit too present. Can't really describe it better, but with some images on the Nec, the monitor simply disappears as if you were holding a print in front of your eyes. Not so with the LG (but maybe this is because it is new). One important point: I wear reading glasses now (+2.5) and when I am sharp in center, I am not sharp at the edges. It replaces a three monitors setup on my second computer and I solved the same issue in the three monitors setup by giving a 30 degrees angle to the external displays so my viewing distance remains constant. IMHO, a situation where I could really benefit from a curved display.
