 Using the Projector to Operate a Computer Connected on a
Network (Desktop Control Utility 1.0)
When Desktop Control Utility 1.0 on the included User Supportware 3 CD-ROM is installed on the computer, that
computer can be operated using the projector over a network.
For example, say you have a PowerPoint file on a computer in your office that you want to use for a presentation at a
meeting. If the computer in the office is connected by LAN to the projector in the meeting room, the projector can be
operated to project the image of the desktop of the computer (Windows 2000 or XP) in the office and display the
PowerPoint file during the meeting. This eliminates the need for taking the computer from the office to the meeting
room.
