DVI DVI In

DVI (Digital Video Interface) is one of the first all–digital video interconnects to carry high definition video. Being pure digital saves DVI from an analog to digital conversion step, which can introduce noise artifacts into the picture. Multiple versions of the DVI interconnect exist, with some versions supporting only digital video, some supporting only analog video, and some supporting digital and analog video. Below is a description of each DVI interconnect.



DVI-D (single link)
DVI-D (single link) Transmits only digital video with a bandwidth 165 MHz. Therefore, this interconnect can support video rendering up to 1920x1080 pixels at 60 Hz or 1600x1200 pixels at 60Hz.

DVI-D (dual link)
DVI-D (dual link) Transmits only digital video with double the bandwidth of single link. Therefore, this interconnect can support video rendering up to 2048x1536 pixels at 60 Hz or 1920x1080 pixels at 85 Hz.

DVI-A
DVI-A Transmits only analog video. The analog signal carries RGBHV data, which is what a computer’s VGA connector carries.

DVI-I (single link)
DVI-I (single link) Capabilities to transmit both digital and analog video as described in the single link DVI-D and DVI-A sections above. Digital video and analog video are incompatible without a converter. Therefore, make sure that a device transmitting a digital video signal only is going to a device that is capable of receiving digital signals. Vice versa, the same is true for analog signals.

DVI-I (dual link)
DVI-I (dual link) Capabilities to transmit both digital and analog video described in the dual link DVI-D and DVI-A sections above.The same restrictions as mentioned above apply for digital or analog only transmissions.
