I have a spyder2 pro, HP Pavilion zv6000 laptop with ATI Radeon 
Xpress200M graphics card that I connected an LCD screen to.  I am 
trying to calibrate the LCD screen.  When I calibrate the laptop screen 
and change the profiles you see the difference on the laptop, but 
nothing changes when I calibrate the LCD screen.  It doesn't change the 
laptop or the LCD screen.  I know when I did this before I got the LCD 
screen to change, but not this time.  Not sure if I changed some of the 
display properties or what. I am running XP pro.  If anyone can walk me 
through how to load the profiles for the extended monitor I would 
greatly appreciate it.

Thanks,

Laura
