I have an existing home theatre with a 110" screen. I have purchased the LSP7T but am having trouble fitting it on screen properly.
I have found that the SIZE/POSITION fine tuning does nothing. At first, I could change the width/height/position values but this seemed to have no real effect on what was projected. Now, the setting is entirely unavailable. How can I change the size and position once my unit is physically in the best position I can place it?
Second, can this be mounted upside down on the ceiling in front of the screen?
Lastly, can I mount this in the back of the room on the ceiling?
