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.

Pericom’s PI3VST01 HPD signal generator generates a monitor detection signal from a VGA source connector to tell the VGA source if an external monitor is connected or not.

PI3VST01 allows notebook makers to shut off the VGA DAC when a monitor is not connected, thus saving 170 mW per DAC. PI3VST01 dissipates only mW.

The monitor detection scheme within the PI3VST01 will not affect normal operation of the video driver.
