DFP 
Digital Flat Panel 
The Digital Flat Panel standard defines an interface between a computer and a digital, flat-panel monitor. LCD monitors rely on digital signal. CRT monitors, however, require analog signals, which is why most video cards translate digital information from your computer into analog format. The DFP standard, adopted by VESA in February 1999, enables a computer to transfer information digitally to an LCD monitor over several meters of cable, without any analog conversion.
