I have a fairly old sharp projector...I mounted it to the ceiling so naturally the image is upside down to get it to line up right I had to flip it right?? Well I have been all through the instructions as well as the menu and only found a way to reverse the image but not flip it?? My friend has a newer projector and theres an option on the menu to flip it- how could mine reverse it but not flip it.??? Does anybody know what i could do??? Thanks-J
