Abstract: A system and method to remotely share a display screen are provided. Packets on a data bus may be detected with a bus sniffer, where the packets are transmitted by a display controller to a first display device over the data bus. The packets may include information describing a graphical user interface displayed in the first display device. A representation of the graphical user interface may be generated in a memory from the packets. The representation of the graphical user interface in the memory may be shared with a second display device over a network with a desktop sharing system. The second display device may display a copy of the graphical user interface based on the representation of the graphical user interface shared by the desktop sharing system.
