Runco Vision 85 사용자 설명서

Throw distance is the distance measured from the front of the projector to the screen. This is 
an important calculation in any projector installation as it determines whether or not you 
have enough room to install your projector with a desired screen size and if your image will 
be the right size for your screen.

You can quickly estimate the throw distance by taking the width of the screen and 
multiplying it by the lens throw ratio; see Figure 3-2. The result of this calculation tells you 
roughly how far back the projector should be positioned from the screen in order to project a 
focused image large enough to fill the screen.

The Vision 85 offers a throw ratio of between 1.86 and 2.45. For example, with a 100-inch 
wide screen, the Vision 85 has a throw distance range of between 186 inches (4.72 meters) 
and 245 inches (6.22 meters).

The Vision 85/CineWide offers a throw ratio of between 1.92 and 2.45. For example, with 
a 100-inch wide screen, the Vision 85 has a throw distance range of between 192 inches (4.88 
meters) and 245 inches (6.22 meters).
