Spyder4 pro says dell u2312hm not wide gamut

I have attempted the spyder 4 pro calibration unsuccessfully.  Message says,  "you listed monitor as wide gamut in type but display appears to be normal".

When I go into   Control- Hardware and sound- Display- change display settings- advanced settings- monitor tab- properties,  it says display is standard monitor,  driver is microsoft 2006 6.1.7600.xxx,  details tab says it is generic PNP.   Should I be using a display driver or let the Nvidia card handle it.

any help appreciated.
