The Nintendo Wii is one of Nintendo's most popular consoles ever, with terrific games like Metroid Prime and Twilight Princess, as well as party favorites like Wii Sports and Mario Party. But when you have a big group playing Wii at the same time, a little television isn't always enough. That's why some people choose to connect the Wii to a projector.
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.
Invest in a newer projector instead of trying to connect an older version to your Wii. Older projectors don't necessarily have the same connectors as newer ones, which may end up requiring users to use adapters to create the proper connections.
Remember that the Wii uses a sensor bar in order to enable the console's motion sensing technology. That means that the console and sensor bar need to be oriented in the same direction as the final projected image. This may require users to get extension cables for their A/V lines, as well as set up the Wii in a separate area from the rest of the actual A/V equipment.
