Dear Meg A. Byte,
What is the best way to project a computer screen on the wall for an entire class to see?
Claire Watts
Watt's up, Claire?
Allow me to shed some light on your question. Although many schools still use the tried and true standard overhead projector, complete with transparencies, markers, and light bulbs, many others are now investing in small machines called LCD projectors, or just projectors. (Newer technology eliminates the use of LCD, thus removing LCD from the product description!) These machines project an image on a computer screen onto an external area, such as a wall or a pull-down screen. Quite simply, you connect the projector to your computer and voila, the computer image is available for all to see.
Admittedly, projectors carry a steep price tag. They can run between $3,000 and $5,000 each. So do your research before you buy. You'll want a good resolution and as many bells and whistles as your budget will allow. Despite the cost, however, for the long haul, projectors are probably a worthwhile investment for most schools.
If a projector isn't feasible, consider purchasing a larger monitor, one big enough so that students can see it from a distance. You may need to drop the display resolution to make the image visible to all.
Now that you know the basics about projecting a computer screen, could you project the future for me?
Meg
