PI3VST01 Datasheet (Pericom Semiconductor Corporation)

PI3VST01, HPD signal Generator

The VGA connector does not have a hot-plug pin to tell the system that a monitor is connected.

More recent video standards, such as HDMI and DisplayPort, save power by adding a hot-plug pin which allows graphics outputs to be powered down when a monitor is not connected.
