Abstract: Embodiments of this application provide a projection display method and an electronic device, and relate to the field of terminal technologies, to dynamically adjust, based on a quantity of source devices, a parameter of display data projected onto a destination device, so as to improve display smoothness and use experience of a user during projection. The method includes: A source device sends a projection instruction to a destination device, where the projection instruction is used to instruct to project a display interface of the source device onto the destination device for display. The source device receives a first broadcast sent by the destination device, where the first broadcast includes a quantity N of source devices that need to perform projection onto the destination device for display. The source device negotiates a first projection parameter with the destination device based on the quantity N of the source devices, where the first projection parameter includes one or more of a projection resolution, a transmission bit rate, or an encoding compression rate. The source device sends first display data to the destination device based on the first projection parameter.
