Installation
Ambient Light ➤ | In general, minimize or eliminate light sources directed at the screen. Contrast ratio in your |
| images will be noticeably reduced if light directly strikes the screen, such as when a shaft |
| of light from a window or floodlight falls on the image. Images may then appear washed |
| out and less vibrant. |
Throw Distance ➤ | 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 |
| 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
