Elite Screens ezCinema Tab-Tension is a free-standing portable projection screen that is offered with a tab-tension system. It swiftly pulls up and retracts using a "scissor-backed" free-standing mechanism that requires no extra tools, accessories or effort. This is the perfect "projector screen in a box" for portable presentations on the go. The matte white material has a wide viewing angle and is masked on all 4 sides for enhanced aesthetics and visual contrast. The screen comes with a black backing to eliminate light penetration for brighter image fidelity. The tab-tension design allows the material to be flatter on the sides for compatibility with ultra/short-throw projectors.
