A video projection screen assembly for the viewing of images projected thereon and designed to be selectively disposed between an exposed, expanded position for viewing and a collapsed position for storage. A viewing screen is mounted on and supported by a support frame structured to dispose and maintain the viewing screen in the vertical, expanded position for viewing wherein the support frame includes a positioning assembly including one or more spring biased sets of arms wherein each arm set includes a gas spring mounted thereon and cooperatively structured to provide sufficient driving force for disposition of the viewing screen into the vertically oriented, expanded position for viewing when released from its collapsed position. The viewing screen is formed from a relatively heavy, durable, material having sufficient flexibility to be rolled upon itself or otherwise disposed in a collapsed position for storage of the screen and the support frame in an out-of-sight location.
