Here is another LCD from our friends at NEC, the MultiSync PA271W.
It has a 10-bit p-IPS panel which has 2560 x 1440 resolution on a 27-inch screen. It is capable of up to 1.07 billion colors from a 4.3 trillion color palette. It also has a SpectraView II color calibration system.
Both versions of this display will ship in May for $1399 with color calibration system and $1649 without it.
