what is the difference between dvi-d and dvi-i
1. DVI-D is the digital format connector. It comes in both single-link and dual-link formats, the difference being that the dual-link connector provides more power and twice the data transmission rate compared to the single-link connector. DVI-D is the most popular type of connector for hooking up DVI cards to LCD monitors.
The DVI connector on a device is given one of three names, depending on which signals it implements: 1  DVI-I (integrated, combines digital and analog in the same connector; digital may be single or dual link) 2  DVI-D (digital only, single link or dual link) 3  DVI-A (analog only)
