A am able to use the Spyder2Pro to calibrate my 2 monitors that are
both attached to an Nvidia AGP video card running under Windows XP.

I have an LCD and a CRT on the same video card, and both monitors look
quite similar with their proper profiles applied.

These are the steps required to do this in Windows with Nvidia cards:

1. Use the Spyder to calibrate each monitor with a meaningful name.
2. Bring up display properties (right mouse on desktop and select
"properties".)
3. Select the "Settings" tab.
4. Click "Advanced" button.
5. Select "Color Management" tab.
6. You will see a list of color profiles associated with the monitor,
probably the profile you created for the primary monitor and some
existing windows or monitor manufacturer's profiles.
7. Click the "Add" button and select the profile you created for the
secondary monitor to add it to the list.  These profiles are now
available to ColorVision's "Profile Chooser" program.
8. The profile that was created for the primary monitor should already
be set as the default - you can highlight it and press the "Select as
Default" button to be sure.

-------------------------------------
9.  When you start the computer, the profile that as been "set as
default" is applied to both monitors, so the secondary monitor has the
wrong profile.
10. Start ColorVision's "Profile Chooser" application.  (Profile
Chooser is automatically installed with the Spyder software on Windows
machines).  A window of it will open on each monitor.
11. At the "Profile Chooser" window on the SECONDARY monitor, select
the correct profile for the secondary monitor.  Now each monitor will
have the correct profile.
12.  Close "Profile Chooser"
13.  Steps 9 to 12 need to be done whenever you restart your computer,
but its easy.
