In addition to owning a good-quality outdoor projector, you’ll also want to get a good projection screen. If you don’t have one, you could use a large, white bed sheet. But if you expect there to be any wind, you’ll want to have the sheet tied down so it doesn’t affect the projected image. You’ll want the projected image to be around 120 inches, if you have room, so your screen should be around that size or a little larger. You’ll also want to be sure to set up any audio, depending on the type of outdoor projector you buy. You might only need the on-board audio speakers or, if there’s an audio port on the unit, you can use external speakers. Also, many projectors let you hook up speakers via a Bluetooth connection.
