Abstract: A plug-and-play device comprises a first plug-and-play interface for establishing a connection with a first computing device and a second plug-and-play interface for establishing a connection with a second computing device. Storage stores code that is automatically executed by the second computing device when the plug-and-play device is connected to the second computing device via the second plug-and-play interface. The code when executed by the second computing device initiates a screen display data exchange between the first and second computing devices through the plug-and-play device. A controller controls the first plug-and-play interface, the second plug-and-play interface and the storage.
