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.
Short for DVI (Digital Visual Interface) Integrated, DVI-I is the connection, or interface used between monitors and computers or home theater systems. DVI-I is used to interface with an LCD or CRT monitor display for digital video output. DVI-I supports both digital and analog. However, it will not use both at the same time. DVI-I detects and chooses digital or analog depending on the connected display. Contrast with DVI-D, which is a digital-only interface and DVI-A which is an analog-only interface.
