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.
The Digital formats are available in DVI-D Single-Link and Dual-Link as well as DVI-I Single-Link and Dual-Link format connectors. These DVI cables send information using a digital information format called TMDS (transition minimized differential signaling).here are three types of DVI connections: DVI-Digital, DVI-Analog, and DVI-Integrated DVI-D - True Digital Video If you are connecting a DVI computer to a DVI monitor, this is the cable you want. DVI-D cables are used for direct digital connections between source video (namely, video cards) and LCD monitors.
