crosen - it sounds like you're looking to drop the projector and screen by the same amount, and I *highly* doubt that's what you actually want/need to do. I would think (based on past experiences) that you'd first set your screen limits to drop that to the desired height, then you'd drop the projector to the point where the top of the screen is at the same height as the top of the lens when the projector is level. That amount would likely end up being way less than 60".
