What room do I install it ? These projectors are designed to be used in a dark room , like a cinema hall . And is that any small light decreases the contrast of the image. Course you can always reduce the image size so that the light emitted by the projector to concentrate more and increase the contrast.
You can fix the ceiling or wall, or simply support it on a table. That itself must leave at least 30 cm of space around the fan grill , otherwise it may overheat the interior light . Note that the hot air stream can be seen to a distance of one meter. What type of screen? If the wall is uniformly white , bulges or defects , you can use it directly as a display.
Another alternative is to buy an expandable screen . Some of them are placed on a tripod, while others can be hung from the ceiling. Its qualities can also be very different as well as how to extend them (electric and manual) .
Based on these factors, prices vary considerably. How far ? Ideally , the viewer must be at a screen distance equivalent to twice (1.87 times exactly ) the width of the image: which translates into three meters for an image , 1.5 meters wide, for example. If you get too can not see at a glance the whole picture.
When placing the projector , there is some room for maneuver, which is what provides the zoom. But beware , it is not abused : its use involves some loss of brightness of up to 40% on some models . What angle? It is important that the light is directed frontally towards the screen where the image is projected . Otherwise, the image will be narrower by one side .
If the shape of the room find it difficult to obtain an emission angle , look for a projector that has lens shift function ( lens shift ), an automatic correction system . What technology is best ? Technology LCD (Liquid crystal display) notable for the quality of the colors. Of course it also has disadvantages : black clearer visibility of the plot between pixels when viewing the screen from about ( grid effect ) and long-term degradation is colores.Si DLP (Digital Light Processing) , its main advantage lies in a range of more authentic black ( darker).
Downsides? Lower maximum brightness , less natural colors and some chromatic decomposition when the head moves quickly ( rainbow effect) . This effect can be annoying, so before you buy , check the store what it ve.Sea such as these technologies evolve very quickly. A current model can not be compared with another made two years ago.
