Screen type is one of the most useful ways to categorize a screen by their function or design.
Where will you be using your projector screen?
Home Theater - A fixed frame screen or an electric retractable screen are both excellent options.
Living Room - A retractable electric screen is a fine choice. However, I would strongly suggest looking into an Ultra Short Throw if you do not already have a projector.
Conference Room - Electric screens are an excellent option to impress potential new clients and help present business data.
At a Convention/Presentation - Portable and folding frame projection screens are your ideal choice as they are easy to set up and breakdown.
Auditorium - Fixed frame and motorized electric screens are ideal choices.
Classroom - For schools we recommend manual screens for smaller classrooms and electric projector screens for larger lecture halls.
Drive-in, Museum, DIY, Outdoor - Projector screen paint is what I would recommend. This paint is speciality formulated to create an optimal projection surface.
