You can set up or install your projector in the following ways:
Mounted on the wall or ceiling
Mounted vertically on a table to create an interactive workspace
Mounted vertically underneath a table to project from behind a translucent screen
Mounted on the wall or ceiling and projecting from behind a translucent screen
Front projection from a table or portable cart (finger touch not supported)
Rear projection from a table or portable cart behind a translucent screen
Wherever you set up the projector, make sure to position it squarely in front of the screen, not at an angle.
If you project from a table or portable cart, or from the rear, be sure to select the correct Projection option in the projector's menu system.
