"Video
Projectors - Your Questions Answered" from the articles section.)
Installing a projection system is always a major undertaking for
any congregation. This page has been designed to help fill in the
gaps for those bewildered by the technology.

Portable or Installed?
|
Some churches use portable data projectors which can
be used in different locations, whilst others have projectors permanently
installed. Obviously, it's handy to be able to move your projector
out of the sanctuary, to use in another location or lock away for
safe keeping. However, the design of many sanctuaries leaves no option
other than to have a projector permanently installed.

Brightness
|
|
|
Image brightness is a key factor in evaluating any projectors performance.
The normal measure of brightness is ANSI Lumens - this is an American
standard which most manufacturers adhere to.
As a general guide, 1000 lumens is usually considered adequate
for small portable screens, classrooms, and some smaller venues.
In anything from a medium sized church upwards, projectors of 2000
lumens and upward are the norm. The brightness you require in practice
is determined by the size of screen and level of background light.

Resolution
|
In simple terms, the picture you get from a projector
is made up of pixels, and the greater the number of pictures the better
the quality and clarity of the projected image. SVGA resolution (800
x 600 pixels) is considered the basic standard, although most new
projectors feature XGA resolution (1024 x 768 pixels). This higher
resolution is a definite bonus if you are showing detailed material,
and also gives smoother looking images on larger screens.

Cabling
|
| All projectors need cabling in order to work - a mains
supply, data connection from the computer, and a video line for VCRs,
DVDs etc. We have a range of solutions available to suit even the
most complicated configuration! |
