This is misinformation. I can calibrate two monitors separately with my spyder 3 elite and it applies two different ICC profiles to each monitor at startup. One is a Mac monitor, and the other is a dell Ultrahsharp and they produce the exact same colors.
As it says, you need two physically-separate GPUs in order for Windows to see the displays as different hardware devices and allow individual choices for the ICC profile (e.g. two individual cards or a 2-head Quadro). You also have to use Extended Desktop mode (Cloned Desktop only uses the ICC profile from the primary screen).
You are sadly mistaken my friend. Two ICC profiles for each monitor on my single graphics card. I could put as many monitor's with different ICC profiles as long as my card has ports.
