Welcome to the world of Dual Monitor Computers. This post talks about DVI and it’s relevancy with Dual Monitor Computer Setup. Digital Video Interface is the full form of DVI and Dual Monitor imply here connecting two monitors to one computer using a Dual Monitor Graphics Card. There are many ways of connecting dual or multiple monitors to a single computer, however here only the concept of connecting Dual Monitors using a Graphics Card & it’s relevancy is discussed.
Instead of going too much technical details of DVI, here basic information is provided to easily know & use the concept. A Basic Desktop Computers need to be connected to Monitors or Display Devices to display output. Now the display output of the Desktop Computer travels to Monitor using a Cable. The Cable has two ends, one end is connected to Monitor & other end is connected to the Computer. Technically the ends joining the cable are known as ports or connectors.
In many Desktop Computers you can find a 15 pin blue colored port to connect the cable to Monitor which is called as VGA Port. Similarly there is another type of port to connect the output of computer to Monitor with the name of DVI Port. Computers are known to work in digital format, however VGA port transfers analog signals to drive the monitor. In contrast DVI ports transfers data to Monitor in Digital, Analog or both formats. There are many types of DVI connectors available such as DVI-D, DVI-A & DVI-I. Each type of DVI connector can be identified by different pin configurations. There are various port converters (such as DVI to VGA) available out in the market as well.
When looking for a Dual Monitor Graphics Card or when buying a Monitor, you must make sure that you would be able to connect the output of the graphics card to Monitor. This is where you might require information related with DVI such as DVI Cable, DVI to VGA Converter, DVI Ports (D, A & I types), etc.
