The Elite Screens SableFrame Series 66.2 x 117.7" Fixed Frame Projector Screen features a CineGrey 3D screen surface, which is an angular reflective front projection material designed to reject ambient light while maintaining superb picture quality. The CineGrey 3D is the perfect solution for rooms that have little or no control over incidental light. This means that it's an ideal fit for family rooms as well as lecture halls, boardrooms, sports bars, training facilities, and other business environments. This is well suited for low-lumen output projectors.
