The image is not rectangular. What should I do?

• Try the following solutions:
  • Place the projector directly in front of the center of the screen, facing it squarely, if possible.
  • If you adjusted the projector height using the projector feet, press the keystone buttons on the projector to adjust the image shape.
  • Turn on automatic keystone adjustments using the projector's menu.
    
    Note: Excessive angles or use of keystone correction (vertical and horizontal) can affect image sharpness and quality.
