Abstract
A video projection switching apparatus includes a screen interface, a display controller, a switching unit, and a plurality of input interfaces. At least two of the input interfaces are electrically connected to the display controller and used for connecting to external input devices. The screen interface is used for connecting to a display screen. The display controller is electrically connected to the switching unit and the screen interface. When at least two input interfaces both input video signals, the display controller first outputs a video signal input from one of the at least two input interfaces through the screen interface according to a preset program. The switching unit outputs a switching signal to the display controller when a user operates. The display controller selects to output a video signal input from another one of the at least two input interfaces through the screen interface when receiving the switching signal.
