Abstract
A method and system are implemented to instantaneously detect a hot plugging of a video connector in a computer device by detecting a change in the electrical state of one ground pin of the video connector. The computer device comprises a video connector having at least two ground pins, a processing unit, and a hot-plugging detection circuit coupled between the processing unit and one of the ground pins of the video connector, wherein the hot-plugging detection circuit is configured to detect a hot plugging of the video connector based on a change in voltage potential of the ground pin.
