DVI stands for Digital Visual Interface. DVI Cables are generally used to connect an LCD monitor to a computer’s video card. The DVI cable is a successor to the VGA cable, which uses analog not digital. Despite it’s name DVI cables do come in versions that are capable of transmitting analog signals.
DVI connectors consist of DVI-D which can only send digital signals, DVI-A, which can only send analog signals, and DVI-I which can send both digital and analog signals. DVI-D and DVI-I types are also available in dual link versions which increase the amount of data the cable is capable of transmitting (thus increasing the available resolution size the cable can transmit). A single link DVI cable can transmit a WUXGA signal, which is a resolution of 1920 x 1200 at 60hz. A dual link can transmit a WQXGA signal, which has a resolution of 2560 x 1600 at 60hz.
Unlike some cables a DVI cable only transmits video. not audio. While the DVI cable was introduced in 1999 it is still in use today although it is quickly being replaced by the HDMI cable due to it’s slightly superior video capability and the fact that it can also transmit audio signals, although on computers it usually isn’t used for audio. Still due to the an HDMI cables high cost DVI cables will likely still be in use in the lower end markets for years to come.
I bought my hdmi cable from lindy.co.uk
