Part of my image is blurred or out of focus. What should I do?

• Try the following solutions:
  • Adjust the image focus.
  • Clean the projector lens.
  • Position the projector close enough to the screen, and directly in front of it.
  • Position the projector so the keystone adjustment angle is not so wide that it distorts the image.
  • Adjust the Sharpness setting to improve image quality.
