Portable Projectors Slim Down, Get Bright

Anyone old enough to have volunteered to help their teacher avoid fumbling with 16mm

film or overhead projectors likely marvels at today’s portable projectors that come

complete with an amazing amount of technology in a surprisingly small and easy-to-use

package.

“

What we considered portable projectors 15 years ago weighed 20 lbs.,” said Richard

McPherson, NEC senior product manager for projectors. “Now, portable can be an 8-lb.

projector or much less.”

You can still buy an overhead projector but it

probably makes more sense to take

advantage of the latest advances, especially

if you want a crowded auditorium to see what

you are presenting.

“

You need a larger screen too because you need to spread that information out so that

everybody can see it,” said McPherson, “Today’s projectors are made to accommodate a

large screen.”

Portable projectors can fit into a shirt pocket or be large enough that it is probably better

if it is permanently installed. They can, among other things, connect to wireless networks

or project data and images from smart phones and tablets. Low-cost operation and

maintenance have become key features and important selling points.

“

Computers, and the need for

different resolutions as-well-as

more complicated content, have

driven much of the

advancements in features found

in today’s projectors,” said

McPherson, “The more content

the greater the need for higher

resolution.”

BRIGHTNESS AND

RESOLUTION

McPherson advises that clients

base their buying decisions on a projector’s brightness, resolution and versatility. This

includes the ability to change projector lenses as necessary. Also, buyers should

determine

how the projector will most frequently be used in order to match

features with the desired

price point.

Other potential features include edge-blending and stacking capabilities. Edge-blending

allows the use of multiple projectors to produce a massive image on a screen without

discernible lines between video segments. Stacking uses multiple projectors with software

that overlaps single

images and increases brightness at a cost that can be less than buying

a single projector with higher light output.

“

Depending the situation, they may need three projectors one day and only need one the

next,” said McPherson

Projectors used in small, well-lit venues can use projectors with moderate brightness.

Larger rooms need even greater light output.
