Standard screens have a 4:3 shape ratio, which is better suited for viewing computer
presentations and standard TV broadcasts. Watching DVD movies or HDTV broadcasts on a
4:3 ratio screen limits the image width and leaves unused screen area above and below the
image. Available screen sizes vary, but are usually up to 6 0 inches (152 cm ) diagon al (the s ame
height as an 80-inch [203-cm] diagonal 16:9 screen).
Considering Screen Mounting Style
Most screens are either floor-standing, wall-mounted, or ceiling-mounted. Consider these
characteristics as you choose which type would be best for your viewing environment:
Considering Color and Surface Quality
For home theater settings, screens come in white or shades of gray. Gray screens (sometimes
called high contrast screens) increase the natural contrast of images projected in rooms with
ambient light by absorbing the room light and preserving the darker blacks. If you have a
dedicated home theater room with dark walls, ceiling, flo or, and furniture, a gray screen may
not provide better contrast than a white screen. However, if you usually project images in a
typical living room or family room with some reflected light, a gray screen will provide better
contrast and a truer viewing experience.
