Abstract
A notebook computer having a display port capable of outputting a vertical synchronous signal, a horizontal synchronous signal, a red signal, a green signal, and a blue signal to an external display device to display an image is disclosed. The notebook computer includes a monitor device built in the notebook computer, an embedded controller capable of outputting an enable signal and a detecting circuit receiving a first signal, a second signal and the enable signal. The first signal is the vertical synchronous signal or the horizontal synchronous signal. The second signal is the red signal, the green signal or the blue signal. When the external display device is disconnected with the display port, the detecting circuit may determine the second signal according to the actuation of the enable signal at a blanking interval of the first signal and switch the image to the monitor device automatically.
