An example of a highly professional rear projection screen
An affordable example of a rear projection screen
Are you a restaurant owner or event organizer? Would you like to show the World Championship live on a big screen in the restaurant? We have collected a few useful tips to ensure your event’s success.
Contact us without obligation, we will clarify the most important questions about installation, brightness and the various projection options.
Outdoor projection is always subject to widely varying conditions. The time of day (sunlight and darkness), number of viewers, location, shadows, etc., all have a major impact on the planning of an outdoor event.
Here you will find a few ground rules that alway apply to outdoor projection.
Never allow direct sunlight to shine on the screen. Outdoor projections in strong sunlight can be improved by means of rear projection and canopy.
Rear projection is a must, at least when projecting a large image outside. With rear projection, the projector casts the image onto the screen from behind. The area between the projector and the screen is darkened using a tunnel (tent, molleton, or tarp).
Examples are shown to the left.
This tunnel, which connects the projector with the screen, must be absolutely lightproof and, optimally, black on the inside surface. At the same time, it also protects the projector from the effects of weather.
Standard lenses have a projection ratio of approximately 2:1, which means an image one meter wide is created when the projector is at a distance of 2 meters from the screen. Because you always want to minimize the distance between the projector and the screen when using rear projection, you needs wide angle lenses. The best ratio is 0.8:1 or less.
Always chose the location with the largest proportion of shadows at the time of the event. Natural shadows can be extremely helpful if you want to keep effort and costs as low as possible.

The best outdoor results are achieved using rear projection screens. There are different screen types with various brightness enhancement (gain factor) characteristics. The higher the gain factor (luminance factor), the better the brightness of the screen. How ever, this also brings with it the danger of hotspots and irregular illumination. A gain factor that is too high can favor the brightness centering so much that only viewers seated in the center can see a bright picture.
The size of the screen should be chosen according to the distance of the most remote viewer. The furthest viewer should sit at a maximum distance of 7.5 times the image width. For example: For a 4 m (width) x 3 m (height) screen, calculate 4 m (width) x 7.5 (factor) = 30 m (distance from the screen). The furthest viewer should be max. 30 m away.
20,000 ANSI lumens are physically double the power to 10,000 ANSI lumens. Subjectively, however, the “felt” increase in image brightness is closer to perhaps 10-30%.
Bar, restaurant, beer garden with fewer than 300 persons, without admission, without sponsor, without fee:
Public broadcasting in bars/hotels/restaurants and other commercial establishments does not require a license from FIFA to the extent that they operate television sets on their premises, that they possess the relevant commercial TV subscriptions, and the necessary local permits, provided that such events are not sponsored and no admission fee is charged.
Although they are deemed to be public broadcasts, FIFA will not require a license for events involving up to 300 people, unless such events are sponsored or an admission fee is charged. This avoids unnecessary paperwork for both the organizer and FIFA.
The following is prohibited:
Licence Fees for commercial public screening:
For a max. 200 sq m, the GEMA fee is more or less € 99 for the duration of the World Championship. Larger events cost more depending on their attendance and the image size.
GEZ fees must always bee paid.
