You can set up or install your projector in the following ways:
Mounted on the wall or ceiling
Mounted on the wall or ceiling and projecting from behind a translucent screen
Front projection from a table or portable cart
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 place the projector vertically, turn on the Vertical Installation setting in the projector's Installation menu.
If you install the projector to a fixed location, turn on the Fixed Installation setting in the projector's Installation menu.
If you project from a table or portable cart, or from the rear, install the projector feet and be sure to select the correct Projection option in the projector's menu system.
