Hi, I wonder if anyone can advise me on a good mount for my projector. I currently have my new Optoma H56 on a shelf on the rear wall - it has to be right against the rear wall for the "throw" to be exact. I want to leave it on the rear shelf but I need a mount that can sit on the shelf with the projector on top that allows me to adjust the angles along the width and depth of the projector (individually adjustable feet). I've hunted around for something like this but can find nothing. Can anyone suggest a suitable mechanism? Thanks.
