Projecta

The DescenderPro is a ceiling-mounted projection screen that combines high-resolution HD progressive materials with new installation features and a motorized ALR surface option. One of the most notable innovations is the ability to easily snap the entire roll with the motor and screen surface into place after the housing has been installed. The new housing design provides a clean surface without gaps or visible screws once the base plate is attached to the housing.

Aspect ratio

Describes the format of image width to image height, with 16:9 being the common TV and office standard. Values such as 21:9 or 32:9 stand for extremely wide monitors, which often replace two old screens next to each other.

Gain factor

The light amplification factor, or gain factor, is an important factor when selecting a screen. Factor tells you something about the reflective properties. An ordinary white sheet of paper has a gain factor of about 1.0. It scatters the incident light homogeneously and diffusely in all directions. Thus it appears practically always equally bright, no matter from which angle you look at it.

Picture walls with a gain above 1.0 try to reflect a certain amount of light more specifically towards the audience, which usually sits axially in front of the picture. Developers achieve this through special surfaces and coatings. They take, so to speak, a small step towards the properties of a mirror. A gain of 2.0 describes a screen that - measured on axis - reflects twice as much light as a perfectly diffuse surface with 1.0. This is why we speak of amplification.
