Digital Visual Interface (DVI)
The Digital Visual Interface (DVI) specification provides a high-speed digital connection for visual
data types that is display technology independent. The interface is primarily focused at providing a
connection between a computer and its display device. The DVI specification meets the needs of all
segments of the PC industry (workstation, desktop, laptop, etc.) and will enable these different
segments to unite around one monitor interface specification.
The DVI interface enables:
1. Reduce signal loss and video noise in signal due to less signal conversion.
2. Independent from display technology, and can be used on LCD, Plasma, LCOS, etc.
3. Plug and play through hot plug detection, EDID and DDC2B.
4. Digital and Analog support in a single connector (DVI-I only).
