Using Spyder2PRO, I am trying to calibrate and profile two monitors 
connected to a PCIe display adapter, ATI Radeon X600.  Monitors are 
Dell 1907 and HP LP2065, both LCD monitors.  The Dell is monitor 1, 
HP is monitor 2, and desktop is extended over both.

When I calibrate the Dell with Spyder2PRO, there is visible change in 
the screen appearance.  If I move from 6500 K to 5800 K, the screen 
appears warmer.  When I check the effect of calibration at the end of 
the process, there is visible change.  Neither of these are true with 
the HP.  In several trials I have, perhaps by chance and by choosing 
different starting points, gotten desktop colors that are similar 
(not perfect, but close).  However, upon rebooting this similarity 
goes away.  When I open Photoshop and open a photo in display 2 and 
move it to display 1, colors change visibly.

While I intend to use the HP for photo editing, I would like for 
there to be some rough consistency between the two.  I don't believe 
this should be impossible.  I fear that I have overlooked something 
obvious, but can't put my finger on it.  Any help out there?

(BTW, I have searched this group's messages and not found the answer.)
