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.
DVI and HDMI connections, for this reason, are subject to the âdigital cliffâ phenomenon. Up to some length, a DVI or HDMI cable will perform just fine; the rounding and reflections will not compromise the ability of the display device to reconstruct the original bitstream, and no information will be lost.
