English W20000-en.book Page 23 Monday, October 22, 2007 3:35 PM Adjusting the projected image Adjusting the projection angle There are four adjuster feet on the bottom of the projector. These can be used if necessary to change the projection angle. Screw the feet in or out as appropriate to aim and level the projection angle. If the screen and the projector are not perpendicular to each other, the projected image becomes vertical trapezoidal. To correct this problem, see "Correcting picture distortion" on page 23 for details. Correcting picture distortion Keystoning occurs when the projector is not perpendicular to the screen and is where the projected picture displays visible as a trapezoid shape like either of the following: • Two parallel sides (left and right, or top and bottom) but is noticeably wider on either side. • No parallel sides. To correct the picture's shape, you can perform the following steps. 1. Adjust the projection angle. Move the projector to be in front of the center of the screen with the base of the lens level with the top or bottom edge of the screen. 2. If the picture is stilled distorted, or the projector is unable to be positioned as described above, you will need to manually correct the picture. • Using the remote control or projector i.
