DFP (Digital Flat Panels) are Digital only, this cable will only work to DVI-D
or DVI-I ports and won't work to DVI-A or VGA. For DVI-A or VGA, a VGA to DVI
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.
