The Kestrel Tab-Tension 3 CineGrey 4D is a floor-rising electric front projection screen with ambient light rejecting technology. The CineGrey 4D is an angular reflective material that incorporates a high-contrast diffusion layer to provide contrast-rich images in ambient light room environments to combat the washout effect typically experienced with matte white materials.The projection screen surface ascends and descends into its housing for a non-invasive solution where permanent installations are not practical.The screen comes with a full control system which includes Infrared and Radio Frequency remote controls along with a wall box controller and 12-volt trigger capability.
