9. A test method for stability of video interfaces, comprising:
transmitting, by a signal generator, multiple video signals to multiple video interfaces of a display;
controlling, by a controller, the display to sequentially display images according to each video signal; and
capturing, by an image capturing sensor, the images displayed sequentially by the display according to each video signal, detecting, by the image capturing sensor, whether an image corresponding to each video signal is abnormal, and transmitting, by the image capturing sensor, a detection result to the controller;
wherein controlling the display to sequentially display the images according to each video signal, including:
receiving a video signal from a video interface currently to be detected;
setting video signals output by other video interfaces except the video interface currently to be detected to 0; and
controlling the display to display the images according to the video signal from the video interface currently to be detected and the video signals that are set to 0 and output by the other video interfaces.
