Abstract
This application provides a screen projection processing method and an electronic device, and relates to the field of communication technologies. By using the solution of this application, when a screen projection source device performs screen projection to a screen projection target device through a screen projection application, if the screen projection application is closed abnormally, a state of a virtual display driver is set to a disabled state. In this way, the virtual display driver will no longer create a virtual display, so that the screen projection source device cannot capture an image used for screen projection in a case that no virtual display exists. Therefore, in a non-screen projection scenario after the screen projection application is restarted, a display screen of the screen projection source device performs display normally without a black screen phenomenon.
