Distance of reach

You need to know how far you must install your projector to complete the space on the screen. Still mounted on its base, each projector must be capable of projecting different picture sizes. The projector manufacturers produce charts and listed the size of the screen depending on the distance that is the projector. We recommend reviewing these tables before deciding where to install the projector in the room.

Ceiling-mounting your projector is a popular and elegant way to set up your home theater. It also requires you to know the optimal fixed distance between your projector and your screen. That's because projectors have different throw ratios.

A projector's throw ratio is the relationship between its distance from the screen and the width of the image it projects. For example, if your projector will be ceiling-mounted ten feet away from your screen, the image it projects will be larger than if your projector is mounted only five feet away.

If your projector has a zoom lens, determine exactly where you wish to mount the unit, and verify that the projector can meet your ideal image size from that distance.

The goal is to set the projector in an ideal spot to light up your projection screen without obstructing the view of the watching audience. The projector likely fit on the coffee table in front of the couch or on the edge of a conference room table. Still there are traffic and cable management concerns with putting a projector within reach of too many people and let's not forget - pets.
A projector with a zoom lens will have a range of throw distances for any given image size, while a projector without a zoom lens will only be able to project one image size at a given distance from the screen. Throw distance is the measurement from the projector's lens to the screen.

Panasonic's SmoothScreen technology eliminates any hint of pixelation, even at very close viewing distances. There is simply no screendoor effect whatsoever on the Panasonic products that have this filter, which includes all of their home theater models.
