I am seriously considering purchasing the HD1000U. I would like to ceiling mount the projector. My media room is 18' x 18' however my ceiling goes from 7'-6" to 10'. That is, on all four walls the walls are 7' 8" tall and then angle in and upward at around a 40 degree slope to the 10' total (hope this makes sense). From what I have read on this projector the actual top of the projected image is a good bit lower than the projector itself. How should I mount the projector? I am thinking I can mount the projector on the "Slope" which could give me the height I need from the floor. Is there a mount that will work on a sloped ceiling? What would you all suggest as a good solution here? Will the HD1000U work in this situation? Thanks in advance for any advise.
