Abstract
A video output system at least includes a first video output terminal, a control circuit, a first digital-to-analog converter, and a first bias voltage generator. The first video output terminal is selectively connected with a first video input terminal of a display device through a signal cable. According to a constant detecting current generated by the first digital-to-analog converter, or the first bias voltage generator, the first video output terminal has a detecting voltage for indicating whether the video output system is connected with the display device. When the video output system is connected with the display device, the control circuit enables the first digital-to-analog converter but disables the first bias voltage generator. When the video output system is not connected with the display device, the control circuit disables the first digital-to-analog converter but enables the first bias voltage generator.
