This high-quality adapter cable allows you to connect a computer with a DVI-I analogue output to a VGA monitor with a built-in VGA cable (i.e. 15 Way VGA Male) Many modern graphics cards feature both DVI-I (digital and analogue) and VGA (analogue) connectors. This cable is useful when you want to connect two VGA monitors to a computer equipped with one of these cards - simply connect the first monitor to the VGA port and the second, using this cable, to the DVI port!
