Solved Dual Graphic Card

In fact, DVI also has analog signals.

DVI-A ---> Analog
DVI-D ---> Digital
DVI-I ---> Integrated (both analog and digital, so with a DVI/VGA, no need for a converter as the adapter will take the analog signal).

Usually, GPU have DVI-I but as Stormy13 said, when there's 2 DVI, maybe only one is DVI-I and the other would be DVI-D.

Look there to understand: Digital Visual Interface - Wikipedia, the free encyclopedia

Look for a GPU with 2 DVI-I connectors.
