Key Information:
- 115 x 115 cm visible area
- 2.5 cm black borders on the left and right
- Dimensions of the tube in cm (W x H x D): 135 x 7 x 7 cm
- Weight: 6 kg
- Powder-coated, white rectangular tube

- Black, light-tight back
- Optimal for home theaters and presentations with a 1.2 gain

The Rollo Professional is ideal for well-equipped seminar rooms. However, it also delivers outstanding results at home in a home theater thanks to its excellent quality. The screen has a very good flatness due to its thick, heavy fabric. The roller screen is multi-stage adjustable thanks to a special mechanism, allowing you to set not only the 1:1 format but also other formats such as 4:3, 16:9, or 21:9. The screen has a gain factor of 1.2, optimized for projections with LCD and DLP projectors, providing a wide viewing angle. A black back ensures that no light is lost, keeping your projection clear. This means you can also use the screen in front of a window. A black border and/or lead ensures increased contrast and better flatness of the fabric. Delivery includes mounting materials, instructions, and a pull cord.

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.
