In an example method, a first device establishes a connection for multi-screen collaboration to a second device. The first device turns off a screen in response to a first event. The first device draws screen content based on a first software signal in response to a second event, to obtain a screen content drawing result. Then, the first device synthesizes the screen content drawing result based on a second software signal, to obtain a screen content synthesis result. The first software signal and the second software signal are software synchronization signals that are generated by a same software signal source in the first device and that have a same cycle. Finally, the first device sends the screen content synthesis result to the second device.
