No reviews out there, yet...and still only 82% CIE gamut (100% sRGB).
Not bad there is also the U2211H the 22" version 1.5" less with the same IPS and 22W typical.
And Dell is not an LCD panel manufacturer so I expect to see more IPS LCD on the market this year.
For now I will keep my NEC 2090UXi (A-TW-IPS) is only 20"(4:3) but I have 1200 lines. and typical power consumption is about the same as 23" Dell 33W but with my settings can go under 20W it uses 6 CFL but I'm thinking replacing them with LED's. Not sure what Dell uses probably CFL otherwise they will advertise the LED.
