The image is not rectangular. What should I do?

• If the projected image is not evenly rectangular, try the following solutions:
  • If the projector is not mounted on the wall or ceiling, place it directly in front of the center of the screen, facing it squarely, if possible.
  • Use the Image Shift setting to adjust the image position, rather than moving the projector.
  • Adjust the projector keystone using the adjustment knobs on the 3-axis adjustment unit.
