10. Presentation Options
With multimedia LCD projectors becoming increasingly affordable
and portable they have become a very desirable technology.
They come in three varieties Super VGA, xGA and sXGA.. xGA
(1024 x 768) machines are sharper than sGVA machines (800
x 600) and sXGA (1280 x 1024) are even sharper still and
are very useful when zooming in on detail.
PowerPoint type presentation
software, clip art, or simple graphics (pie and bar
charts) |
800 x 600 |
SVGA |
Excel type spread sheets and detailed
graphics such as (architectural drawings) |
1,024 x 768 |
XGA |
CAD/CAM applications or ultra high-resolution
graphics |
1,280 x 1, 024 |
SXGA |
Try and avoid large screen televisions unless they do not
need to be moved and have a picture quality and size that
works in classrooms. There is nothing more off-putting to
teachers and students than trying to see the detail when
there is none to be seen. Teachers would gladly sacrifice
one or two new computers in order that students could see
the web site you are talking about, see the power-point
presentation, or watch the vide clip and see what is happening.
