Home Theaters

Home theater projectors in this category includes a 16:9 and 16:10 (with the ability to display 4:3 and 5:4), demonstrating improved quality of video images and low noise fan. The demonstration of a computer image. So, you have to determine to which group belongs desired projection. To further the choice of model was simpler, let's get acquainted with the fundamental characteristics of projectors, each of which is particularly important for specific applications. Main characteristics – it is the luminous flux, resolution and contrast. Luminous flux Luminous flux – one of the most important performance projections. The higher light output, especially with large screen sizes can operate the projector and the lower the requirement to darken the room. Unit of measurement of luminous flux is the ANSI-lumens.

Now mikroportativnye projectors weighing 1,0 – 2,4 kg have a luminous flux of 1200 – 2500 ansi lumens – enough for presentations in the negotiations or during seminars and training sessions, video viewing in smaller rooms. Heavy-duty thread 3500 – 6500 ANSI-lumens are models weighing from 3.5 to 15 kg – they can be used in large conference rooms and even movie theaters. When selecting the projector needed to calculate the value of luminous flux to the following factors: the desired image size, dimensions and shape of the room where the projector will be installed, as well as the nature of ambient light. For example, a large but very dark room, you can get big and bright image Using a projector with a relatively low luminous flux.
