Hello, we use the ceiling mount together with the BenQ W2000W and it works perfectly. The beamer holds perfectly and I have never had to adjust the image so far (over 1 year), i.e. once it has been adjusted properly, the beamer keeps its position. Only the weight of your projector (Benq: 3.6kg / Optoma: 10kg) could be decisive, as this corresponds to the maximum payload of the ceiling mount ... - hope it helps ... Greetings, hoelzli
