My thoughts:
(1) A video card in fact *is* a digital component but the voltages that go
out of it (from the D/A converter on the card) are very analogue ones. And
at least each different make/model of video chip (and to a certain extent I
would also say, every single video card) produces different (analogue)
voltages from the same (digital) input. And even your computer's power
supply consists of analogue components which (very slightly, indeed) affect
the output of the video card.
(2) Most calibration utilities do not only affect the monitor's behavior but
also write a lookup lable (LUT) into the video card. And I'm not sure this
LUT "survives" if you plug it into another PCI/AGP slot.
So you'd be better off re-calibrating (or at least writing a new profile for
the new config) your monitor when hooking it up to another computer.
Hope this helps,
