Are there any differences between DVI and HDMI? DVI stands for Digital Video Interface. HDMI stands for High Definition Multimedia Interface. First let's discuss what each of these interfaces is and how it works.

Digital Video Interface, or DVI, is actually a predecessor of HDMI. Digital Video Interface was made by the Digital Display Working Group (DDWG). The original design for DVI included conversion of analog signals by converting analog into a digital signal. This was done so that both analog and digital signal monitors could be accommodated by DVI. Data is transmitted by the use of transition minimized differential signaling (TMDS) protocol and provides a digital signal from a PC's graphics subsystem to the display unit.
