Re: You can still calibrate it with a 3rd party device....

I understand the difference but why is that advantageous to someone? Why should I care whether the calibration data is stored on the monitor or the video card?

Assuming you are working with 8-bit color, my understanding is that when you calibrate in the monitor, you get 256 correctly mapped choices per color (Red, Green, Blue). When you calibrate in the video card, you are essentially throwing away the choices that don't correctly map, and then remapping to the remaining choices, so you lose precision and range of colors.
