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 and video projectors
(although
many older projectors need attachments to do data)
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 or
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.
