One front projection screen, four projection formats. Everything you could possibly want in a tab tensioned projection screen! Ceiling recessed, its  motorized screen and masking system are linked electronically provide four different projection formats at the touch of a button, all in a ceiling recessed Access case. A flat black mask on a second motor-in-roller converts the projection screen to your choice of four formats: 1:1.33 NTSC, 1:1.78 HDTV, 1:1.85 WideScreen and 1:2.35 CinemaScope. During format change, the center line and width of the viewing surface remain constant while the mask and projection screen move simultaneously into their factory preset positions. Motor-in-roller is mounted on special vibration insulators so operating noise is dramatically reduced. The reflective surface is laminated to a woven textile base and hangs suitably flat because of the stability of the material and the weight of the bottom dowel.
