DVI input is a digital input (rather than the standard analogue) and is a true plug and play input. It can also be used on some Sanyo projectors for optional devices such as wireless communication. Slowly but surely, the new DVI (digital video interface) standard is making its way into the display market and showing up in graphics cards. Projector vendors like Sanyo with an eye toward the future--and much sharper output--are selling projectors with DVI-I ports.
