VGA or HD15 is the analog connection used to connect computers and laptops to projectors or additional monitors. In light of Analog Sunset, VGA is considered a legacy connector, and will be replaced with a digital HDMI or DisplayPort connector in the near future.
The VGA interface is not engineered to be hotpluggable (so that the user can connect or disconnect the output device while the host is running), although in practice this can be done and usually does not cause damage to the hardware or other problems.
