Vidikron 40828 manual Estimating Throw Distance TD

Page 27

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 3-2.

The Vision 10 has a lens throw ratio of between 1.40 and 1.60.

The Vision 12 has a lens throw ratio of between 1.42 and 1.65.

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.

For example, with an 8-foot (96-inch) wide screen:

The Vision 10 has a throw distance range of between 134.4 inches (3.41 meters) and 153.6 inches (3.90 meters).

The Vision 12 has a throw distance range of between 136.3 inches (3.46 meters) and 158.4 inches (4.02 meters).

Estimating Throw Distance (TD)

Vision Model 10

Minimum TD = Screen Width x 1.40

Maximum TD = Screen Width x 1.60

Vision Model 12

Minimum TD = Screen Width x 1.42

Maximum TD = Screen Width x 1.65
