What gfx card do you have Smoke?
Same as RVT1K, my Datacolor software just works and I can't find much about it on the interweb.
I've got 2 monitors at home which are calibrated for my desktop, then I use the same monitors with my works laptop that's got the two monitors and its own screen calibrated all with seperate profiles. I've got an old Nvidia gtx950 in my desktop, and the laptop is running a low end ATI card (I think)
