Square projection screens for overhead and slide projectors or specialist installations where a sqaure image is required.
Projection screens designed for displaying images from 4:3 aspect ratio projectors such as SVGA (800*600), XGA (1024*768) and SXGA+ (1400*1050).
Projector screens designed primarily for home cinema and film screenings. The aspect ratio matches 720 and 1080 high definition video projectors.
Many modern widescreen laptops and projectors have a 16:10 aspect ratio. If your projector has a resolution such as 1280*800 or 1920*1200 then choose from these screens.
