The Celexon Rollo Professional series screen is characterised by the excellent workmanship of all materials and components used. With the matt white coating and a gain factor of 1.2, a very good colour reproduction is achieved. Even in bright light conditions, the projected image appears rich in contrast and offers sufficient depth. Ideal for presentations and home cinema. The screen has a gain factor of 1.2, which is optimised for projections with LCD and DLP projectors and allows a wide viewing angle. This makes the Rollo Professional series ideal for high-quality seminar rooms or home cinemas. Black edge and back. A black back ensures that no light is lost and that your projection always looks clear. This means you can also use the screen in front of a window pane without any problems. A black border on the left, right and bottom as well as a black leading edge at the top also ensure increased contrast and better flatness of the screen surface.
