You may want to consider what your requirement is for your output. Are you preparing files only for printing on printer with a fairly wide gamut? Or are you also need to prepare images for presentation on the web (client galleries, your website, etc.)?
I have the NEC 2690 (v2) and find it a pain to process images for web, so I am looking for a quality sRGB display to pair with the 2690. I'm looking at the NEC 2490wuxi2 display for this because it is also hardware-calibrate-able using the SpectraView II software. For my needs it has become clear that I need a dedicated sRGB display for some work, so this is the solution that I believe is best for me. I have not seen other NEC options that are sRGB and compatible with SpectraView II in the 22 to 26" range, but maybe I have missed something. I'd prefer not to spend as much as the 2490 for this secondary task, but haven't found a model that is height adjustable to match the 2690, black, etc.
