although your video card has two connections, you cannot profile BOTH 
monitors. I believe this is the case with one video card. You will 
need two video cards to profile both monitors. Someone please correct 
me if I'm wrong.

I have a dual monitor setup under Win XP that is driven from a single 
video card (NVidia Quadro FX 3400).  The monitors are an IBM C220P 
(CRT) and a DELL 1905FP (flat panel).  I have profiled them both 
using the Spyder2 Pro and am able, using the Microsoft Color Control 
Panel Applet, to have the appropriate profile applied to each.

Win XP does NOT support profiles for two monitors off a singel video 
card in its native form.  MS did release the color control applet to 
allow this to be done.  Without it, you would need to have a separate 
video card for each monitor.

As it installs, it requires you to manually set the profiles each 
time you boot.  You can, however, add a parameter to the command 
string to have it done automatically at boot time using the profiles 
you assign to each monitor - assign them using the manual mode.  To 
have it run automatically, add a "/L" to the end of the command 
string (here is mine):

"C:\Program Files\Pro Imaging Powertoys\Microsoft Color Control Panel 
Applet for Windows XP\WinColor.exe" /L

Create a version of it with this parameter and place it in your 
Startup folder.  When Win XP starts, if the profiles make a visible 
difference, you can watch the profile for the primary monitor get 
loaded and applied to both monitors and then later when the applet 
runs, you can see the secondary monitor get modified to reflect its 
profile.

I always use the same name for my two profiles so that I do not have 
to keep changing the profile id that is being used by the applet.

This works on my system.  I also found that since my CRT monitor is a 
bit old, I had to use the video card application to boost the 
brightness and contrast a bit to get it back in the range where I 
could do the correct setup with the Spyder 2.  With the flat panel, I 
had to try to tame the contrast and brightness down a bit.  During my 
boot process, I can actually watch the intermediate step where the 
video card software applies these corrections before the applet 
applies the profiles.

My guess is that the applet is the early release of support from the 
next Windows level.  Apple has been way ahead of MS on this.

I hope this helps,
