In the original IBM VGA implementation, refresh rates were limited to two vertical (60 and 70В Hz) and three horizontal frequencies, all of which were communicated to the monitor using combinations of different polarity H and V sync signals. The VESA DDC specification does however include a standard for hot-swapping. The VGA interface includes no affordances for hot swapping, the ability to connect or disconnect the output device during operation, although in practice this can be done and usually does not cause damage to the hardware or other problems. In both its modern and original variants, VGA utilizes multiple scan rates, so attached devices such as monitors are multisync by necessity. Modern connectors also include VESA DDC pins, for identifying attached display devices. DE-15 is the most accurate common nomenclature under the D-sub specifications: an 'E' size D-sub connector, with 15 pins in three rows.ДЄll VGA connectors carry analog RGBHV (red, green, blue, horizontal sync, vertical sync) video signals. The VGA connector is a three-row, 15-pin D-subminiature connector referred to variously as DE-15, HD-15 or DB-15. Дevices continue to be manufactured with VGA connectors, although newer digital interfaces such as DVI, HDMI and DisplayPort are increasingly displacing VGA, and many modern computers and other devices do not include it. Other connectors have been used to carry VGA-compatible signals, such as mini-VGA or BNC, but ' VGA connector' typically refers to this design. Originating with the 1987 IBM PS/2 and its VGA graphics system, the 15-pin connector went on to become ubiquitous on PCs, as well as many monitors, projectors and high-definition television sets. The Video Graphics Array ( VGA) connector is a standard connector used for computer video output. In the male connector, this pin numbering corresponds with the cable's wire-and-solder side.
