1. dual display: card has inputs to support 2 displays (i.e 2 CRTs, 2 LCDS, or 1 CRT and 1 LCD)
2. DVI digital video input: some LCDs (mostly the higher end ones) use this input, most of the time it provides a clearer picture on the LCD
3. TV out : always you to transfer video to a TV
4. tv tuner always you to watch tv on the computer
5. video in allows to to transfer video from an outside source to the computer
