Power Point Projector

Thanks to the Power Point projector, lectures and sales talks don’t have to be boring anymore and there’s no grappling with heavy weight projectors with the coming of age of mobile data projectors.

Lightweight Presentation Projectors

Lightweight data projectors are handy for the travelling businessperson or professional who gives frequent PowerPoint presentations; small data projectors (e.g. NECO, SANYO, EPSON) are ideal for boardroom or classroom presentations.

Portable projectors provide the same satisfying visual presentations from cinematic beamers and are not too bulky to handle. Fact is you can hook up your iPhone, iTouch, and iPod, enabled camcorders, digital cameras, and DV cams to a pocket size Pico projector, the smallest projector now available from different manufacturers.

Apart from their small size, these projectors make for a perfect Power Point projector. The keys to a successful PowerPoint business or scholarly presentation are screen brightness, image clarity, and gray scale function. This is precisely why you should choose the appropriate presentation projector to get the most out of your Power Point presentation.

The key features to look for in data projectors or a Power Point projector are:

* brightness levels
* contrast
* resolutions
* gray scale

Screen Brightness

The brightness beamed from the projector enhances onscreen image or graphics and this brightness from the lumens powering the projector. However, the brightness of your presentation will also be determined by the size of the venue. A small conference room or auditorium demand varying degrees of brightness for the Power Point presentation.

For small conference rooms, a minimum of 1000 or 11000 American National Standards Institute (ANSI) lumens will be perfect, meaning there will be no need to switch off moderate lights to get a clearer view of the pictures or details and although these works well in darkness too. For big auditoriums, a projector should have 4000 lumens to give clear pictures and graphics.

Contrast / Gray Scale

This feature is not a must-have projector feature for regular boardroom presentations but if you are presenting a report in a large auditorium where lighting is controlled, a higher contrast ratio (400:1) would be applicable. Higher than this is useless because the human eye cannot perceive the color contrasts in an ambient lighting.

Gray scale is not much of an issue with business presentation when the presentation deals with figures and statistics but the contrast between black and white should be smooth without the whites jumping out of the screen.

Resolution or Display

Most Power Point projectors offer pixel compressing and expanding functions but this degrades display of graphics sharpness. The commonly used projector and computer resolutions are the Super Video Graphics Array (SVGA) and eXtended Graphics Array or XVA. A more expensive version is the SXGA, which offers 1152x864 resolutions, but for office and school presentations, the SGVA and XVA work fine.

Presentation projectors have their true or native resolution, one where the projector performs at top level and when compatible with your laptop or PC, the images are clearly defined.

When shopping for your business Power Point projector, always check out the projector’s compatibility with your laptop before testing out brightness levels, contrast, resolutions, and gray scale function; the rest will be easy.
