Can anyone help? 1.)Got a Hitachi PJTX-100 and I want to know if this universal mount will attach to it? http://www.ebuyer.com/customer/products/index.html?rb=6265127997&action=c2hvd19wcm9kdWN0X3Jldmlld3M=&product_uid=79195 2.)Also is says the mount pole length is 30cm.Now from my ceiling to around the top of the projector screen, if the PJ was flat it would be pointing directly at the top of the screen.Is this correct? I.E how far down does a PJ have to be from the ceiling to the screen? 3.)Does anyone know if this mount has swivel up down etc?? Many Thank's D.
