An IT technician needs to connect a graphics card to either a legacy VGA monitor or a modern digital LCD panel by using passive adapters. Which connector variant is specifically designed to carry both digital TMDS signals and legacy analog RGB signals through the same interface, allowing either type of display to be used?
DVI-I (Digital Visual Interface - Integrated) includes the full set of TMDS pins for digital video and an extra group of four analog RGB pins surrounding the flat blade, so the port can drive a digital DVI-D display or (with a passive adapter) an analog VGA monitor. DVI-D omits the analog pins and carries digital only; VGA is analog only; HDMI is strictly digital (video plus audio) and contains no analog video pins.
