This projector screen is in perfect condition and we are only selling since we are moving to a new house.
This screen should be used with a regular projector or a single laser UST (ultra short throw) projector.
This is an ALR (Ambient Light Rejection) screen that is able to block light reflections that would otherwise affect other screens. The screen also has a perforation to allow sound through the top of the screen (i.e. for a center speaker that is mounted behind it).
I can show this as working correctly in our theater room in-person if needed.
