The adoption of LCD technology in computer screens has led to the development of the DVI standard (digital video interface). Early LCD screens converted the analogue signal from the computer into a digital signal within the LCD display. Significant improvements in image quality have resulted from the now widespread availability of graphics cards with digital outputs thereby avoiding any signal loss from a conversion to analogue in the graphics card and then back to digital at the screen.

A new standard connector has been developed for the Digital Video interface comprising a rectangular block of 24 pins for the digital signal plus 4 pins either side of an earth pin for transmission of a conventional analogue signal where required.
