Projecter screen

If the angle of reflection is about the same across the screen, no distracting artifacts will be formed.

What to Look for in a Projection Screen Screen size - Before opting for the most massive projector screen you can get your hands on, be sure to measure the space where you intend to put it. A larger screen size means less luminous luminous power per unit solid angle per unit area and thus less contrast in the presence of ambient light. Unfortunately, at the perpendicular direction used for gain measurement, mirror reflection and retroreflection are indistinguishable, and this has sown confusion about the behavior of high gain screens. This effect can be lessened by decorating the room with dark colours. Fortunately, the Spectrum series comes out of the box fully assembled with included hardware for both wall or ceiling installation or an optional in-ceiling trim kit for a hidden installation if you want to go fancy. Frequently quoted gain levels of various materials range from 0. This is a measure of reflectivity of light compared to a screen coated with magnesium carbonate , [4] titanium dioxide , [5] or barium sulfate [6] when the measurement is taken for light targeted and reflected perpendicular to the screen. Screen geometry[ edit ] Square-shaped screens used for overhead projectors sometimes double as projection screens for digital projectors in meeting rooms, where space is scarce and multiple screens can seem redundant. With a total view space of Other screens with higher gain are semi-retroreflective. This differs from semi-specular screens where the hot spot's location varies depending on the viewer's position in the audience. Semi-specular high gain screen materials are suited to ceiling-mounted projector setups since the greatest intensity of light will be reflected downward toward the audience at an angle equal and opposite to the angle of incidence. Screens with high gain also have a narrower usable viewing angle , as the amount of reflected light rapidly decreases as the viewer moves away from front of such screen. The inch x inch size equates to inches diagonally, which may or may not be favorable to non-square shaped screen lovers.

Thanks to the degree viewing angle and a design that works both horizontally and vertically, you can let the whole neighborhood enjoy a movie night or just you and the family.

This differs from semi-specular screens where the hot spot's location varies depending on the viewer's position in the audience. Hot spotting is less of a problem with retroreflective high gain screens.

If the audience stays relatively close to the projector, a curved screen may be used instead without visible distortion in the image geometry. Very high gain levels could be attained simply by using a mirror surface, although the audience would then just see a reflection of the projector, defeating the purpose of using a screen.

This differs from semi-specular screens where the hot spot's location varies depending on the viewer's position in the audience. The inch x inch size equates to inches diagonally, which may or may not be favorable to non-square shaped screen lovers. The object of this design is to have the screen reflect the projected light back to the audience, effectively making the entire screen a giant "hot spot". Unlike mirrors, retroreflective surfaces reflect light back toward the source. The AcousticPro transparent screen is designed to be suitable for both hidden-speaker or a rear-speaker set-up, which allows breathing through the screen for a more lifelike audio experience. These screens have an aspect ratio of by definition. They work best for setups where the image source is placed in the same direction from the screen as the audience. While the omission of those features is notable, the overall price tag and combination of superb build quality and quiet motor make the Vivo an excellent choice.

Highly reflective flat screens tend to suffer from hot spots, when part of the screen seems much more bright than the rest. The matte white surface offers outstanding color quality for real-world color reproduction.
