A configurable shield and methods related to same by which the ambient light in conventionally illuminated venues can be largely prevented from falling onto or around a screen such that images displayed on the screen are generally not degraded in quality. The configurable shield includes shield components that are preferably of a durable, yet light weight construction such that the components can be easily transported, assembled, and moved into position for use, then disassembled by one or a few individuals. The shield components include a shielding element-of a composition and having a construction such that the shield is generally non-translucent to light-and a sizable positioning element that provides additional structure to the shielding element and allows it, and thereby the entire shield to be positioned in a wide variety of configurations as needed such that the shielding element can be positioned adjacent to or in contact with the screen so that ambient light can be generally blocked from falling onto the viewing surface.
