Страница: 29 / 174

This installation section explains how to install the projector for optimum results.
To do this, it is necessary to determine the following:
1. The type of screen and whether front or rear projection is to be used.
2. The projector location and therefore the type of lens to be used.
3. The method of mounting for the projector.
4. The type of input source to be used with the projector.
Screen Requirements
As virtually all commercially available screens will give a pleasing image you
should choose according to your individual requirements. However, to achieve
optimum results we recommend a low gain (1.2 - 1.3), non-perforated screen for
front projection, this will keep hot spotting and light loss to a minimum whilst
providing wide viewing angles.
Regardless of the type of screen used, it is important that your screen is of sufficient
height to display the images at the aspect ratios intended to be used. Use the
following tables to check that you are able to display the full image on your screen.
If you have insufficient height, you will have to reduce the overall image size in
order to display the full image on your screen.
