Electric ScreensElectric screens are wall or ceiling mountable screens that use electric motors to power the screen "up and down".
Projection screens come in a multitude of styles and models, and within the electric screens there are arrays of options.
Manual ScreensManual pull-down screens are wall and ceiling mountable, and can be tensioned like electric screens, although not all manufacturers will tension manual screens. Like their electric counterparts, manual screens take up less space than fixed screens, but manual screens are much easier to mount. They don't have electric motors to add weight and complexity to installation.
Fixed ScreensPerfect for the Board-Room or your own Home Theater, fixed frame screens are generally cheaper than electric screens and because they are mounted to frames, they are perfectly flat, making them ideal for home theater applications.
