Window systems which developed since 70's, usually runs on the workstations. This new development gradually prompted users to request new applications such as multivision and window migration over the computer network.
In this thesis, we propose an architecture for the network-wide Virtual Display in window systems. With Virtual Display user can have several displays available at his disposal and can freely determine the size, the location, and the configuration of his own. The Virtual Display is supported by separation of communication part and window abstraction in the window systems.
