I have this Desktop it’s an Hp pavilion HPE H8t series. It has a 1 GB DDR Ram with a Radeon HD 6670 Graphics Card. All I wanted to know is whether the Graphic Card could have a Digital user interface (DVI) so that I could use it on my Monitor, Because my Monitor Has a DVI –D connection  and I want to have a digital kind of connection with it, what do I need to use so that I can link that up ?
Can a Graphic Card have a Digital user interface (DVI)?

Radeon HD 6670 Graphics Card has a Digital User Interface (DVI) port. Â Therefore if your monitor has a DVI connector you can connect your desktop computer to the monitor using a DVI connection. Â In order to do that you should have a DVI cable. There are three types of DVI connections; DVI-Digital, DVI-Analog, and DVI-Integrated. As your monitor has a DVI-D connection, you should use a DVI-D cable which can be used for direct digital connection between video card and monitor.Â
