Blurry image [projector] — LG Help Guide: Causes, Checks & Fixes

Projectors are imaging devices that use light to project images on a screen in front of them. The clear advantage of a projector over any flat panel display televisions lies in filling incredibly large screen sizes and can usually convert any opaque flat wall into an impressive movie silver screen.

What to Check First

  1. Is the area around the screen brightly lit?
  2. Are the keystone settings correct?
  3. Is the distance between the projector and the screen appropriate?
  4. Are there stains or dirt on the lens?
  5. The distance between the projector and the screen is referred to as the projection distance.
  6. The recommended projection distance may vary depending on the projector model and the aspect ratio of the screen.
  7. Please note that, if the distance between the projector and the screen exceeds the recommended projection distance, the screen may not appear clear.
  8. Use an air blower to remove stains and dust particles from the lens.
  9. Gently wipe the lens using a soft cloth.
  10. If you wipe the lens while the projector is operating or immediately after turning it off, the coating may come off.
