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

• Try the following:
  • There may be dirt or smears on the projection window. See Cleaning the Projection Window.
  • Adjust the focus using the focus lever. See Focusing the Image.
  • Lower the projection angle to reduce horizontal keystone.
  • If you're projecting from a computer, you may need to adjust the Tracking and Sync settings. See Adjusting Signal Settings.
