Legacy Video Connectors

All Legacy Video connector types with specifications and compatibility.

Legacy video connectors predate the digital era and include VGA (DE-15, analog RGB), DVI (digital and analog variants), and composite RCA. While largely superseded by HDMI and DisplayPort, VGA persists in enterprise projectors and older monitors. DVI-D provided early digital video before HDMI's consumer adoption. These connectors are important for compatibility with older equipment and are commonly bridged through active adapters.
