I am going to help a friend install his RS-1X this weekend. He has a platform that sits about 7' up on a rear wall. He says the RS-1x can sit right side up like a table top install and the lense shift will lower the picture. His screen is a 102'' fixed mount starting about 3 feet off the floor. I told him I believe, as with most projectors, that it needs to be ceiling mounted and therefore turned upside down. He doesnt want to do that and just wants it sitting on the shelf 7 feet up. Can this be done on the new X model? Thanks in advance.
