Abstract
The present invention provides a presentation system, a display device, and a program which realize a smoother presentation performance in case where information a presenter wishes to refer to is displayed in a terminal but not in a display device. The presentation system of the present invention is structured, for instance, by connecting a PC 100 and a projector 200 via a LAN 50. A display unit of the PC 100 can be set up to display information including, for example, explanatory notes, but when making the projector 200 display an image, the information will not be displayed by executing a data modification which makes the information invisible. The information such as the explanatory notes may be placed at an arbitrary location on the display unit 102 and this enables a smoother presentation performance.
