2007 meeting rooms are usually equipped with digital projectors that speakers can use to present PowerPoint slides and other visuals stored on their laptops.
However, road warriors who sell goods or speeches in temporary venues cannot expect such comfort in their speeches.
They had to drag their projector just in case.
Today, this is not a chore because the size of the projector has declined over the past four years, while the image quality has improved.
Now, there is a compact portable projector to choose from below4-
It is lighter than the telephone directory in some cities.

The style projector is not meant to show a rich color in a dark room, just like a family movie --
A theater projector.
Instead, most people have designed optical systems that favor brightness rather than color, so that they can project a clear spreadsheet image even when the fluorescent lamp is turned on.
NEC provides a good example of these lightweight projectors: the NP60, which has been widely used since January (
$1,299 in project torcentral. com).
The NP60 has a bulb that can emit 3,000 lumens, enough light, and a sharp 100 lumens.
An inch diagonal image of the screen or wall, even if the lights in the meeting room are flashing.
The projector weighs only 3 lbs. 5 pounds;
It is easy to see its large display screen in a room for 40 or more people.
The arc bulb that produces light lasts about 2,000 hours;
The cost of the replacement is $329.
The projector includes a sensor that automatically pairs the image and a sensor that focuses the lens.

For example, when the audience has two or three people in a cubicle --
Another new projector works well.
These small devices called pocket projectors use L. E. D. ’s, or light-
LEDs, instead of arc lights for larger portable projectors. The L. E. D.
The original light emitted by the projector is much smaller than their arc and produces smaller images

But if there is no meeting room, you need to do a sales demo in a small borrowed office or hotel lobby, and these projectors can do that --
Provided there is a wall nearby where you can project images.
Samsung offers one of the projectors, Pocket Imager SP-P310MEMX, ($749)
Launched in January. It weighs 1. 5 pounds.
The power cord is connected to an AC adapter that adds 1. 25 pounds;
Batteries sold separately ($149)lasts for 2.
Less than a pound, 5 hours.
The brightness of the Samsung projector is 50 lumens, and the light is small, but enough to work effectively within a short distance.
For example, it creates a clear 35-
Diagonal image at a distance of 4 feet inch. Its L. E. D.
More efficient than incandescent lamps, with a life of about 10,000 hours.
Portable devices like Samsung and NEC may initially be purchased for work.
But they also have other apps.
When the work week is over, some take them home, stick them on the console, or plug them into a DVD player to watch the movie.
However, before projectors become popular consumer goods, their costs may drop a bit.
To see how well the projectors work, a friend and I tried them out with PowerPoint shows and movies.
First, we tried using PowerPoint to connect the Samsung pocket camera to the laptop.
It is fast and easy to do so.
However, the pocket camera comes with a local or built-in
The resolution is 800 by 600 pixels, called S. V. G. A.
, Displayed in aspect ratio or display of 4: 3.
But the aspect ratio of the laptop I use with Pocket Imager is 16: 9 and the resolution is 1,366 by 768.

I'm afraid there's not one projector or laptop-for-
A game in the solution.
In some devices, this difference can cause some problems, such as cutting off a part of the image.
But Chris Chinnock, president of Insight Media, a market research firm in Norwalk, Connecticut.
Companies specializing in the display industry say pixel-to-
Pixel matching between the laptop and the projector is not mandatory as the proper software on the projector can handle many input differences.
"The projector has to accept input in all formats and display them on a panel with only one resolution," he said . ".
"A good projector can do this in a limited range.
"In this case, when I plug the projector into the laptop, the projector recognizes the video input of the laptop and automatically shrinks to S. V. G. A.
The display is clear and easy to read, better than three people squeezing around the laptop trying to decipher the same PowerPoint slides.
I also plugged Pocket Imager into my DVD player to watch the movie "notorious".
"The image is clear and the color is strong when I turn off the lights.
There is no fan rotating in the projector in the movie; although L. E. D.
We throw away some heat, which is far less than the Arc Light, so there is no need to cool the fan.
Advertising because of this quiet background, I think the small speakers built into the laptop are enough to listen to the soundtrack of the movie.
They are, I can follow the conversation.
But by connecting the system to an external speaker, the sound is greatly improved.
However, the picture was so compelling that I had to force myself to turn off the show after 20 minutes and go back to work.
We also tried the NEC projector.
It's easy to set up, and soon it shows a huge image of PowerPoint shows and movies in my liferoom wall.
I'm going to invite my neighbor over for popcorn.
Although portable projectors on the market are now small, they will shrink further. Chinnock said.
