  • Why is there a black spot on my projector?

    What do black spots on a projector mean? Small black spots can mean either that the external lens or the internal LCD projector element inside is dusty. However, if black spots persist after cleaning, it can be way more technical. It could be overheating, or a major technical fix is required.
