The image isn’t rectangular, but
■Make sure the projector isn’t placed off to one side of the screen, at an angle, or the image won’t be rectangular. Place it directly in front of the center of the screen, facing the screen squarely.
■If you’ve tilted the projector upward, the image will be broader at
the top. Turn on Auto Keystone correction as described on
page 60 or hold down the 
or 
buttons on top of the projector until the image is rectangular.
The image contains static or noise.
■If you’re using a computer cable longer than 6 feet, or an extension cable, the image quality may be reduced.
■Keep your computer and video cables separated from the power cord as much as possible to prevent interference.
