This high quality cable allows you to connect a computer with a DVI-I analogue output to a VGA monitor with a 15 Way VGA Female connector (i.e. a monitor with a removable VGA cable). 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!
