At the same time, a small but very bright room may need a projector with a powerful light beam. With the luminous flux is directly related to the brightness screen image (it is directly proportional to light flux), so many manufacturers in the specifications of multimedia projectors prefer to use the term brightness as a more intuitive most consumers, although this is not entirely accurate in terms of physics. Actress and filmmaker addresses the importance of the matter here. Resolution projectors predecessors multimedia projectors were projectors to show computer images, it is not surprising that the most important characteristic of the projector is native resolution – the actual number of points of the matrix, forming an image, normally provided by horizontal and vertical. These dots are called pixels – 'elements Pictures' reduction of pisture element. Resolution of the projector is focused on computer video standards: Most modern projectors have a resolution of class svga (800 x 600 pixels) or xga (1024 x 768 pixels). Projectors are available with higher resolution – Class sxga (1280 x 1024) and even a uxga (1600 x 1200). The higher the resolution of the projector, the more detailed images it can display. Every modern projector has the function of digital interpolation (compression or tension) of the image and is able to work with a resolution of one or two notches above and below the baseline, but the image quality will be better if the native resolution projector is aligned with the resolution of the computer showing the image. When you select a projector often deal with the question: 'What resolution is required when the projector will be used only for demonstration videos?'.
