This DVI port can be used to connect a single monitor or video display directly to the graphics card itself or by using a display adapter such as a DVI-to-VGA or DVI-to-HDMI converter.
Secondary DVI Port
The secondary DVI port for ATI Radeon HD 4800 series graphics card can be used to extend the desktop using a dual-monitor system or connect to another display device such as an HDTV or projector.

Besides the two DVI ports on the 4870 X2 card, the graphics card also includes a 7-pin HDTV output connector for connecting the graphics card to display on an HDTV or standard television. A 7-pin output cable can be connected to the output connector and allows for the connection of a HDTV device using composite or standard RCA cables.
