Hello,

I wonder if anyone could advise me about the graphics card specifications when wishing to profile a system with dual monitors?
I am planning to purchase a Spyder4 Pro or Elite in the near future. I understand they are both capable of profiling dual monitors on one computer, as well as the Elite being able to profile a projector.
My question is whether the graphics card in the system needs to have any special capabilities before the Spyder is able to profile both monitors, or whether any graphics setup will suffice?
I'm a newbie on this group so hope I've made my query understanadable.
Many thanks. J.G.
