  • Patent number: 5859623
    Abstract: An intelligent display system presentation projection arrangement and method include the conversion of presentation display information into portable document format information for supplying it to an intelligent display system, which subsequently converts the portable document formation information to presentation display information. A controller responds to the converted information for controlling a projection display unit for causing the display presentation images to be projected onto a remotely located viewing surface. The intelligent display system of the arrangement replaces the separate computer with a unit which is either connected to the projection display unit, or incorporated therein. By utilizing the conversion to portable document format information, any computer platform may be employed, and the information is displayed at the highest resolution available to the projection display unit.
