Speckled whiteboard display

For the last few months my projector has displayed salt n' pepper pixles on my board making it difficult for my students to see what I project. Can someone please advise me how to fix this problem.

I really love the board and unfortunately do not want to get rid of it especially since my school has little funds to pay for a replacement.

I do hope the fix is easy and something I can do on my own with little help.

Looking forward to getting a response.




  • If this same issue is present while no video cabling is connected to the Projector in question, we would recommend reaching out to our support team with a pictures of what is being displayed by the Projector with and without video cabling connected as well as the serial number of the Projector in question.  We would then be able to further advise on whether a replacement or repair would be recommended.
