I3D Display hardware should be configured by knowledgeable system and video engineers to be fully functional. Although some discussion is included in this manual, professional assistance is recommended as there is a large amount of specialization in assuring that all of the components are functioning at their highest levels. Under normal operation, most users should only be concerned with turning on and off the different components (although, due to ongoing display research, the hardware configuration may change occasionally, at which time your system administrator should notify you of the changes.) The following is a description of the common equipment used in Spatially Immersive Virtual Reality Displays.
