Many people pay attention to the projector's performance when building a home theater to purchase a projector, such as brightness, contrast, and image quality enhancement technology. But often overlook the most important point: projection distance, of course, the recent rise of laser projectors is another matter (about the introduction of ultra-short-focus laser projectors: "How to see the 100-inch large screen in the 10 square meters room" .
On the surface, the projection distance refers to the distance between the projector lens and the curtain, which seems to have little to do with building a home theater. However, in practical applications, the projector's projector distance is a very critical parameter, because it directly determines the size of the screen that the projector can cast, especially if you decide to hoist the projector in the living room. Since the living room width of most living room theaters is limited, it limits the projection distance of the projector, which in turn limits the maximum screen size you can get.
For example, if you want to achieve a 100-inch screen in a living room with a width of only 3 meters, then this means that if you have to buy a short-throw projector (such as the BenQ w1070) to cast at less than 3 meters. 100 inch screen, otherwise you will get less than 100 inches of picture.
So how do we choose a home projector?
First, it is necessary to determine the installation position of the projector and the screen;
Second, carefully measure the horizontal distance of the projector installation position from the screen installation position. Remember to subtract the size of the projector body and the size of the curtain from the wall when measuring. Since we may not be able to determine the projector model at this time, it is recommended that the size of the body be deducted by about 30 to 40 cm, and the size of the curtain from the wall is generally about 10 cm. That is to say, if it is installed in the living room, the distance from the wall to the wall at both ends of the living room minus 50cm is your estimated projection distance. For example, if your living room is 4 meters wide, the estimated projection distance is 3.5 meters.
Third, the size of the curtain is determined according to the size of the video wall and its own needs.
Fourth, based on the estimated projection distance and screen, the models of several projectors are selected.
Fifth, choose a product that meets your image quality needs and functional requirements from the selected projectors.
Sixth, it is best to measure the distance of the fuselage according to the selected final model, and then determine whether the projection distance meets the demand.
