Things You'll Need
Instructions
Place your Wii in a position near or beneath the locations of the projected image. Place the sensor bar above or directly beneath the projected image, but try to keep it at a level roughly central to the ceiling and the floor.
Place your projector on the opposite side of the room.
Connect your Wii to your sound system as you normally would using the included A/V cables to set the stereo sound.
Run the video cables from the Wii console to the projector. This is the tricky part: the Wii's native A/V connector is not long enough to reach farther than 8 feet, so if you're going to place the projector farther than this you'll need a video cable coupler and a second (or even third) video cable to complete the connection.
Turn on your Wii and test that the projector is working properly while connected. This also means testing the position of the sensor bar to ensure that you are getting a good signal and that you are able to easily control games while playing using the projected image.
