Portable projection screen assemblies include a case comprising a flexible projector screen held on a roller, the screen has a high ARR and a high-gain and can be adapted for use in uncontrolled indoor ambient lighting conditions. The case is configured with releasably matable first and second housing members and a slidably collapsible frame that slides open in a side-to-side orientation and unrolls the projector screen to at least one predetermined viewing configuration and closes together to encase the screen and frame therein. The projector screens may be particularly suitable for use with low-lumen projectors.
