Abstract: In a process of accepting projection by a first device, a second device obtains first information, to adaptively adjust one or more of a frame rate corresponding to a projected interface, a size of an application display region corresponding to a projected interface, display resolution of the second device, or video resolution corresponding to a projected interface. In this way, an image processing resource and a processing capability of the device can be allocated on demand to enhance a projected picture and reduce load of the second device.

Abstract: This application discloses screen projection methods and systems and related apparatuses. In an example method, a first electronic device may send first display data corresponding to a first screen projection window on a second electronic device and second display data corresponding to a second screen projection window on the second electronic device to the second electronic device. The first electronic device may further send third display data and fourth display data to the second electronic device. In response to determining that the third display data is different from the first display data and that the fourth display data is the same as the second display data, the second electronic device may render and display a third screen projection page in the first screen projection window based on the third display data and display a buffered second screen projection page in the second screen projection window.

Abstract: This application provides a display method and an electronic device. The method is applied to a first electronic device, and the method may include: The first electronic device detects a first operation of starting a first application. The first electronic device matches a window of the first application; and when the first electronic device determines that the matched window of the first application is located in the first electronic device, migrates the window of the first application to a second electronic device for display. The technical solutions can be applied to projection technologies. When an application is switched from the first electronic device to the second electronic device for display, data and a status of the application can be retained to avoid restarting the application.

Abstract: A source device sends, to a destination device, application information of at least one source device application installed on the source device. The destination device displays an icon of the at least one source device application in a first interface, and displays, in the first interface, an icon of at least one destination device application installed on the destination device. In response to an operation performed on an icon of a first application, the destination device obtains first display data generated during running of the first application on the source device. The destination device displays an application window of the first application based on the first display data. In response to an operation performed by the user on an icon of a second application in the destination device application, the destination device starts the second application, and displays an application window of the second application.

Abstract: An application interface display method includes, when an electronic device detects a first user operation of scaling an application interface, a system display pixel density is generated corresponding to the first user operation, where the system display pixel density is not a system display pixel density set by a current system. A change of a system configuration triggers an update of an application setting. After the system display pixel density dispatched by the first user operation is obtained, a first application loads a corresponding application resource and displays an upscale or downscale application interface.
