It refers to leaving the current color balance of white in place, and
profiling to it, instead of using the white end of the video card curves to
change to color of white; which has the unfortunate side effects of also
changing the luminance of white, and potentially throwing off your gray
balance.
With CRTs the white balance can be set with the RGB gain controls before
profiling, and it is this balance that is the "native" whitepoint. This can
be "emulated" on LCDs, but since the controls adjusting the white balance are
not hardware adjustments like in a CRT, there is no hardware advantage to
precalibrating an LCD, though there may still be software advantages.
Monaco, for reasons I could never fathom, has never offeres advanced monitor
profiling capabilities like a Native WhitePoint option, RGB gain adjustments
and targeted white and black luminances. But it appears they have finally
gotten religion and will soon be releasing an advanced monitor calibration
package for the first time. I'll be interested to try it.
