A window is mounted in a wall between two adjacent rooms. The window has at least one suspended particle device glass pane that can be switched from a clear window mode to a partially reflective, partially translucent screen mode. A video image, such as a television program, can be projected onto the pane in its screen mode and is simultaneously viewable from either side of the pane and thus either of the two adjacent rooms. The window allows a parent in a kitchen, for example, to view continuously the programs children in an adjacent den are watching without physically leaving the kitchen to visit the den. The window screen provides dual room video program viewability without requiring multiple television sets.
