Choosing a projector and a huge screen for movies?

Question

Do it yourself

Good afternoon, colleagues.
I ask for help in choosing a projector and a huge screen for a personal outdoor outdoor cinema. What projector parameters should I look at? What numbers/letters should be in these parameters? With permission, everything is clear, but about brightness, a lamp, for example - no.
What should be the screen material?
The projector can be located from the screen at a distance of up to 20 meters, at a height of up to 4 meters. The screen should be at least 3 meters diagonally.

Answer 1

From experience I can say this:
1) The projectors are all different for selection. The best thing to do is look at the picture yourself. TTX personally does not tell me anything. Well, except for very simple types of max. permission.
It seems like they put two projectors from the same price shelf, similar performance characteristics, but the difference is simply huge.
2) Such projectors are expensive. HD starts at 1.5k.
3) If you choose by eye, then look at the whiteness of white and the blackness of black :)
4) Since you will take it to an open cinema, you will need a more powerful lamp.
Well, 20 meters for a personal cinema is strong :)

Answer 2

Since the cinema is large and open, the most important parameter should be the light output. Therefore, it is worth considering projectors with a large number of lumens. In the category “up to 200 tr” there are not so many projectors for home theaters with real Full HD and with sufficient brightness, at most a dozen, here they are . Therefore, you can drive in the name of each model and look for reviews of real owners.

Answer 3

There is a special screen-paint for outdoor use, a 4m2 screen comes out from 1 liter of coating. Try to consider this option, it will be cheaper and better than a conventional tension screen. Wind, rain and other bad weather will not spoil the image quality.
