Screen Innovations (SI) adds a new aspect ratio to the Black Diamond Motorised projection screen line-- CEDIA Expo 2013 visitors can check screens with either 16:9 or 2.35:1 aspect ratio in sizes of up to 138-inches.
Available with either flush or external mounts, Black Diamond Motorised is a single-motor design with 4 custom helixes and a spool of aircraft cable claiming to silently lower a thin wing containing the rolled screen from a recessed ceiling-mount cassette.
When the cable-hung wing stops it lowers a small tube to an adjustable, pre-determined image height, leaving only the image space in sight.
According to SI Black Diamond screens require no masking or black drop material, leaving no visible material above, blow or on either side of the screen surface and allowing for projected images "suspended" in air.
Screens in 16:9 ratio are available in 80-, 92-, 100-, 106- and 110-inch sizes, while 2.35:1 versions are available in 110-, 120-, 132-, and 138-inch sizes, all usable with ceilings up to 3.3m high.
