Projectors

A video projector is a device that receives a video signal and projects the corresponding image on a projection screen using a lens system. All video projectors use a very bright light to project the image, and most modern ones can correct any curves, blurriness, and other inconsistencies through manual settings. Video projectors are widely used for many applications such as, conference room presentations, classroom training, home theatre and concerts. Projectors are widely used in many schools and other educational settings,[1] sometimes connected to an interactive whiteboard to interactively teach pupils.more

Zoombereich Beamer

Guten Tag. Mein Beamer für's Homekino hängt an der Decke. Linsenmitte 223cm über Boden. Die Leinwand ist davon 4m entfernt und sie ist 195cm breit. Der Strahl meines Beamers überschiesst die Leinwand beidseits um ca. 15cm - leider. Ich suche einen Beamer, mit welchem das Bild in 4m Diestanz auf die Breite von 195 hinunterzoombar ist. Wer weiss Rat? Beste Grüsse, Josef Felber
