  • Hello! I've reviewed the datasheet for the Optoma DS-3120PMG+ manual pull-down screen. It details a 120" diagonal screen with a 4:3 aspect ratio, designed for wall or ceiling mounting, featuring slow retraction mechanism and aluminum casing. I'm ready to answer your questions about this screen.
  • What is the native aspect ratio of the screen?
    What is the screen gain?
