HD15

HD-15 is the high-density 15-pin D-sub connector most commonly associated with VGA computer video cables. It is part of the D-sub connector family and is also known as DE-15 in the D-sub nomenclature. The connector carries three analog video channels (red, green, blue), along with synchronization signals and multiple ground pins; many implementations also route a 5-volt supply and the DDC data/clock lines used for EDID communication with displays.

Physically, the HD-15 uses 15 pins arranged in three rows of five within a trapezoidal shell. On cables, the plug is typically male, while displays and adapters use the female receptacle. Standard VGA cables use screws on the sides to secure the connection, though some compact or locking variants exist.

Origin and usage: The HD-15/DE-15 VGA connector was standardized for PC video in the late 1980s and became the de facto interface for analog computer displays through the 1990s and into the early 2000s. Although many modern systems have migrated to digital interfaces such as DVI, HDMI, and DisplayPort, VGA/HD-15 remains common in older hardware, legacy setups, and some professional environments.

Variations and compatibility: There are shielded and locking variants of the HD-15, but the 15-pin arrangement remains compatible only with other HD-15/DE-15 connectors. Care is typically needed to ensure pinout compatibility for signals such as EDID and DC power when connecting different devices or using adapters.
