How much light is in the building?

Picture Quality
Resolution
Does it need to be portable?
Projectors are now as small a book where a a few years ago they were the
size of a fruit box.
SIZE
of SCREEN
Most projectors can do
6 to 10 metres wide however light is a key factor and the bigger the picture
on the wall the better the resolution needs to be

Data Projectors vs Video
Projectors?
Nearly all projectors today
work with DVD's, video players, laptops and computers. Some work with smart
cards, wireless etc. So in that case their is today no difference between
Data Projectors vs Video Projectors.
What is DLP™
technology?
Digital Light Processing
is
the world's only all digital display. DLP™ technology uses an optical semiconductor
to recreate source material with a fidelity analog systems cannot match.
Is easy terms quality like
a DVD (Digital) player rather than a video player (Analogue)
What are the main resolutions?
SVGA is resolution
of 800 by 600 pixels
Short for Super VGA,
a set of graphics standards designed to offer greater resolution than VGA.
SVGA supports 800 x 600 resolution, or 480,000 pixels.
XGA is resolution
1024 by 768 pixels
Short for extended
graphics array, a high resolution graphics standard introduced
by IBM in 1990. XGA was designed to replace the older 8514/A video standard.
It provides the same resolutions (640 by 480)
True Resolution vs Native
Resolution? (Normal vs wide screen)
If a projector's native
resolution is 1024 x 768 (XGA), that means that the actual number of physical
pixels on the display device is 1024 x 768. In some projector models, specifications
show compatibility with higher resolutions. This is achieved through the
use of compression technology. Compression technology displays a perfectly
acceptable image, but is not matched pixel for pixel from computer to projector
to screen.
