VGA
VGA cables carry an analog signal rather than the digital signal that HDMI
and DVI carry, so the PC has to convert the video signal from digital to analog
before sending it along the VGA cable. VGA is widely used for connecting both
desktop PCs and laptop PCs to monitors and to projectors. Few TVs have VGA
ports. Figure 12-3 shows a VGA port and connector. You will also see VGA ports
and connectors referred to as D-sub, which is short for D (indicating the shape)
and subminiature (indicating that the connector was smaller than other connectors
used at the time??”but not anymore).
VGA D-sub connectors and ports are the same size as some other types of D-sub connectors
and ports that have different numbers of pins and are used for different purposes. For example, a
nine-pin D-sub connector is used for serial ports. Before inserting a D-sub connector in a D-sub
port, check visually that the number and arrangement of pins on the connector matches the
number and arrangement of holes on the port.
