They cost less than a big TV and broadcast much larger images. But they are a difficult purchase to succeed: here’s what you need to know.In the department store’s TV department, there are huge picture boxes. The richest customers can afford a mastodon with a screen two meters wide. His images will pale, however, compared to those diffused by a projector – higher than a man standing, four meters wingspan.
The first question to ask yourself, if you plan to buy or offer a best outdoor projector, is simple: what is my usual place in the cinema? The last rows? The image of the projector will probably seem aggressive and tiring. The first ranks? You will be captivated by the total immersion that comes with a projector when you watch an intimate film, and by the great spectacle that action films provide.
No need to ruin: there are good projectors around 500 euros, against 5000 euros for a TV of two meters wide (85 inches). In theory, projectors are therefore an excellent deal, for moviegoers, survivors, and gamers. In practice, however, a projector is a complex purchase, much more difficult to achieve than buying a TV.
We rarely manage to put 4 meters of image in his living room, and the installation is laborious. Windows, in particular, do not mix well with a projector. The faintest light dulls the contrast, to the point of wiping the image. So you have to methodically caulk the living room to prevent light from passing.

It takes a large living room to enjoy a large image. To have a large image, you have to move the projector back. To find out the size of the image in advance, measure the depth of the room and multiply that number by 0.6. Your living room is 2 meters deep? The image will be 1.20 meters wide, like that of a TV 55 inches to 500 euros. Which is very disappointing.
Fortunately, some projectors are equipped with a “wide-angle”. At 2 meters distance, the image rises to 1.7 m, like a 70 inch TV. The Bestvela site lists all the projectors on the market. It automatically calculates the image size according to your living room.
Do you have a living room with enough recoil to display an image 5 meters wide? You will probably have to revise your ambitions downward, as it will also measure 2.8 meters high. However, most homes ceiling at 2 m 40. Under a ceiling of 2 m 40, the maximum width for a 16/9 format image is 4 m 20.

The right projector costs 500 to 800 euros, but the bill does not stop there. If your windows do not have shutters, you will have to invest in curtains or blackout blinds to block the daylight. Blackouts are particularly effective: glued to the wall, they prevent any stream of light from filtering.

If you have a HiFi system, you are saved: connect your projector to enjoy the sound. But it is tempting to afford a sound system with five speakers to perfect the illusion of cinema. These speakers will cover the slight blower noise produced by the projector. Rates start at 150 euros.
Third expense: the projection screen. The image can be projected on a white wall provided it is clean and smooth. In the opposite case, the defects of the wall are seen in the image. The most economical solution is a white awning of 2.20 meters wide: one can find at from 30 euros. Count a hundred euros for a real projection screen 3 meters wide.
Finally note that the projector lamp is not eternal. Its average life is 3000 hours. This is not a detail, because the replacement lamps are expensive: 300 euros on average. If you watch five films a week, the lamp will last six years. But if you watch 4 hours of TV a day, it will only last two years.

Preferably placing a projector in height to avoid the spectator’s heads not intersect the stream. The recommended position is vertical to the viewer, glued to the ceiling. Fixing brackets exist around 50 euros.
Once fixed, the projector should be oriented, because if it is laid flat, the image is not centered in the middle of the wall. It must therefore be tilted, and sometimes even returned. After this tilting maneuver, the image is distorted: the top is wider than the bottom. It must be straightened by the remote control of the projector by adjusting the level of the “trapeze”.
There remains the question of wiring. The video source is usually far from the projector. We are often forced to use a 10-meter HDMI cable. This is the maximum length for HDMI: beyond this, there is a risk that the video signal will not reach the projector. Avoid poor quality cables. There are also wireless video transmitters that carry up to twenty meters, like the WDP01 BenQ (350 €), very effective.
