Installation
Throw distance is the distance measured from the front of the projector to the screen. This is | Throw Distance |
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 |
|
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. |

Estimating Throw Distance
Throw Distance (TD) = Screen Width (w) x Lens Throw Ratio
Vision 85 Throw Ratio: 1.86 to 2.45
Vision 85/CineWide Throw Ratio: 1.92 to 2.45

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).
