To project a rectangular (non-distored) image, you do not need to align the projector exactly with the center of the screen. By using the horizontal lens shift dial, you can place the projector to the left or right of the screen's center, by up to 25 percent of the image's width when projecting with a 16:9 aspect ratio. Make sure the projector faces straight ahead (at a 90-degree angle to the screen). Note: If you place the projector too far left or right, your image will not be rectangular. Place the projector at a suitable distance from the screen to obtain the desired image size, as indicated below. Note that the Zoom adjustment also affects image size.
