DVI vs. VGA. VGA and DVI connectors are used to transmit video from a source (like a computer or tablet) to a display device (like a monitor, TV or projector). The main difference between VGA and DVI is in the way the video signals travel. VGA connectors and cables carry analog signals while DVI can carry both analog and digital.
You can run a VGA monitor from a video card that supports this type of signal. A dual link DVI-D/I cable has two sets of data and can be used to run larger monitors such as the HP LP3065 or Apple 30 display (at 2560x1600).If you have a monitor and card with a DVI-I connector then the monitor can use the analogue or digital signal.o, The analog signal is carried over extra wires that is present in a DVI-I cable that is not in a DVI-D Cable.
