You can switch between wide gamut and sRGB using the monitor's control buttons.
There are several selections - for sRGB, native, custom, and presets.
There is also NEC NaViSet software that I downloaded that might let you do this via the keyboard but I haven't looked at it yet. Anway, it takes just a few seconds to do it via the control buttons and is clear and easy.
Yes it is like 2 for one. I don't think I'd be happy with a monitor that only works in wide gamut because most programs are not color aware and normal icons and sRGB photos viewed in wide gamut look very punchy.
