The image isn’t square, but trapezoid-shaped.
If you’ve tilted the projector upward by extending the foot, the image 
will be broader at the top. If it is tilting downward, it will be broader 
at the base. To correct this, hold down the 
Shift button on the 
projector’s control panel and press the top or bottom 
Keystone 
button until the corners of the image are square.
The image contains static or noise.

Make sure the input signal matches the connected source. Check

Input B option is set to YCbCr or 
YpbPr when a computer is connected, the images may look too
