These days a clear, precise image on your computer screen is something which most people take for granted, but it was only a few decades ago that monochrome computer screens were the norm.
One of the main reasons for the bright and incredibly detailed imagery we appreciate today is the adoption of the Digital Visual Interface (DVI), a digital protocol which allows a digital video data to be carried from the source to the display without compression or loss of quality. This is why flat screen LCD computer monitors and digital projectors now display images that appear life-like and super clear.
Although there is a new interface proposed for development in the near future (Unified Display Interface, or UDI), DVI is currently the most technologically advanced visual interface for flat screen monitors and video graphic cards, and has effectively replaced the old standard, Video Graphics Array (VGA). Most video graphic cards manufactured presently are compatible with both VGA and DVI.
There are three DVI formats or types of connection which all have unique uses. DVI-D and the corresponding DVI-D cables are used to create a direct connection between video cards and monitors, allowing a faster and uncompressed transfer of data. DVI-A and DVI-A cables are responsible for transferring a DVI signal to an analog monitor or display. DVI-I and DVI-I cables are able to carry out transfers of data from digital source to digital monitor and analog source to analog monitor, making it the most diverse of the three. All three types of cables are relatively inexpensive and can be purchased from any good quality electronics or computer store.
