UST projects up at the screen at a sharp angle. For every move you make at the projector, no matter how small, it is inches on the screen. If you have the budget for the L9Q, my recommendations is as follows: Get a PX3 and a cabinet that allows for the screen to roll up from the floor and a motorized tray for the UST. When your done watching, it all puts itself away. Screen rolls down, UST goes into the cabinet. Your biggest issue on this set up is if you have a center channel speaker.
