The Spectrum Tab-Tension 2 CineGrey 3D® Series is part of Elite Screens CE-Retail line of electric projection screens that uses the CineGrey 3D® angular reflective material. It’s a reference quality front projection screen material formulated for environments with minimal control over room lighting. The CineGrey 3D® was designed to enhance picture brightness, offer accurate color fidelity, and improve contrast levels. Typical matte white surfaces wash out the images when ambient light cannot be controlled. The CineGrey 3D® is the best choice for having a projected image with a balanced color temperature and contrast under such conditions.
