Query: Beware DVI cable formats

This DVI cable is a DVI-I cable. At the time of my order, product description did not provide this detail.Took me 1/2 hour to figure out why I couln't plug this into my dell laptop video port. I was not aware that there are two DVI cable formats, a DVI-D and a DVI-I. A DVI-I port will accept both cables. A DVI-D port will NOT accept a DVI-I cable.
