VGA is Analog only, this cable will only work to DVI-A or DVI-I ports and won't work to DVI-D. For DVI-D, a DVI to VGA converter would be needed instead of this cable. DVI Notes:Because the Digital signal of DVI is low voltage and noise sensitive, it is not recommended to extend a DVI cable over 20 feet. The analog signal on analog cables may be able to go longer distances.
