Ultra/Short-throw projectors require a flat projection surface since the projector’s light is closer to the material. Non-tensioned screen materials may exhibit minor wave or curls which may be more pronounced if using an ultra/short-throw projector. We recommend using a Fixed Frame Screen or a Tab-Tension screen with PVC such as our CineWhite® flexible material which will provide adequate tension throughout the entire projection surface.

Our Aeon CLR®, EDGE FREE® Fixed Frame is recommended for table-top ultra-short throw projectors in an ambient light room environment. Please click here to learn more about the Aeon CLR®.
