Alternative PC displays that have a 1000:1 dynamic contrast ratio currently available which you might also want to consider include because of it's better review score, the Eizo ColorEdge CS230, or the Benq BL2710 ($1,705.18).
If the contrast ratio of this medium monitor is not high enough for you then you might also want to consider the MultiSync EA244WMI ($249.99) (25000:1 and higher rated), or the MultiSync EA294WMi ($518.97) (25000:1 and higher rated) both from NEC; or the NEC MultiSync EA273 ($342.99) (25000:1 and cheaper).
