1.3 gain

Gain describes screen reflectivity relative to a reference surface. A 1.3-gain screen is designed to return more light toward the audience than a 1.0-gain reference. In practice, projector output, viewing angle, surface uniformity and ambient light still matter.

Three-layer PVC and black backing

The merchant describes the screen as a three-layer high-gain PVC surface with a light-blocking black backing. Black backing is useful when there is stray light behind the screen because it reduces transmission through the material.

170-degree viewing angle

A wide stated viewing angle matters for backyard groups because guests rarely sit in a perfectly centered row. The 170-degree claim suggests the product is intended for broad seating layouts.

Long-throw and UST compatibility

NothingProjector lists both standard long-throw and ultra-short-throw projectors. UST projection is demanding of screen geometry, so careful assembly and tensioning remain important.

Three height positions

The legs offer three quick-slide height positions according to the merchant. That can help when switching between low camping chairs, lounge seating and a more conventional backyard row.

Tool-free folding frame

The merchant describes a snap-lock frame and a three-minute setup process. Treat that time as a manufacturer claim rather than a guaranteed personal setup time; first assembly, anchoring and leveling can reasonably add time.
