Im using windows 7, but my display profile box ..in View NX 2 , is alway blank.
Yes. Like I said...ViewNX gets the necessary information from Windows. You don't need to select anything within ViewNX. That's why the button takes you to the monitor management dialog of Windows.
But within Windows Color Management, you want to make sure that the calibration tool you're using doesn't create a Windows Color System profile. The profile has to be a .icc or a .icm profile.
