With so many options to choose from, buying a power point projector for an upcoming graphic presentation can be a difficult task for someone who is non-technical.

If you go looking on your own, the first thing that the salesman will tell you is about resolution and brightness and will use other accepted industry buzzwords, but now you’ll know what they are talking about.

In the best case scenario, your projector will operate natively at the same resolution as your video source, in this case the laptop containing your power point presentation.
Amazingly, not long ago the common resolution used to be rather crude VGA (640 x 480), this was later replaced by SVGA (800 x 600) and the more modern quality XGA (1,024 x 768). One can even venture into the really high end resolutions such as SXGA and UXGA, (1,280 x 1,024) and (1600 x 1200) respectively. This ultra high-end resolution comes with a high price tag. Many projectors can operate at numerous resolutions but they always have a default or native resolution.

Projector brightness is measured in lumens. The brightness of a projector in lumens is a very important specification to consider when doing power point presentations on the go or even in a conference room with the lights on. Huge venues or brightly lit rooms that remain so during a screening require projectors that are capable of a great amount of lumens, possibly 5000 or more. Less lumens would be needed for a small audience, with a smaller screen in a well darkened room. In this case 1000 lumens could work fine. When you see the term ANSI lumens, just know that ANSI is a common standard method of measuring lumens.
Another important factor to consider is “throw distance”, this is the distance that your projector should be from the screen. For projectors that are designed to operate in large venues, further than 15 ft back from the screen, large throw or long throw lenses are the norm. With a short throw presentation projector, your can make a presentation with the projector behind you, close to the screen and not have to worry about casting a shadow over your wonderful power point graphics.
Compatibility between your projector and laptop is also very important for smooth on the go presentations. Be sure that the resolution of both the projector and your laptop are compatible, ideally the same. Most of the time this is not an issue. None the less, be sure that regardless what kind of projector you purchase that it has all the cords and other port attachments that you’ll need. Again, it’s exceedingly important that everything is compatible with your laptop.
