I found the answer to my question I think.

"If you have plugs that are DVI-D, they will accept a DVI-D or DVI-I cable. If you have plugs that are DVI-A, they will accept a DVI-A or DVI-I cable. If you have plugs that are DVI-I, they will accept any type of DVI cable.
If you have mistmatched plugs, such as DVI-D and DVI-I or DVI-A and DVI-I, you may use either a DVI-I cable or the cable that matches the other plug. For example, you may use a DVI-D cable on a DVI-I to DVI-D connection, but not a DVI-A cable.
Note: You may not mismatch a DVI-D and a DVI-A connection."
