With a widescreen 16:9 aspect ratio, this 100-inch screen with 1.1 gain works well with your 1080P and 4K ultra HD projectors to deliver a brilliant theater-like experience. The slightly opaque screen suits both front and rear projection; for rear projection, place the projector behind the screen instead of next to the audience. The polyester screen is strong and less likely to crease. It stands steady too thanks to its strong and robust frame. No tools and screws are required for the assembly; the poles firmly connect via the fasteners in the joints for an effortless setup and takedown.
