If you need to purchase a power point projector for an upcoming presentation or deadline, time is of the essence and with all the technical jargon and options, this task can really seem overwhelming. We hope this article will meet your needs for some simple and basic information to help in your power point projector search. When searching for your presentation projector, you will often come across the basic terms you learn about in this article, but now you will have the understanding to make a solid decision.
Tiny dots of light called pixels make up the image you see on your laptop computer screen as well as the image shown by a modern projector. Your video source (usually your computer) determines the initial resolution, if you are soon updating your computer you may want to get a projector that can handle the more modern higher resolutions natively.
Resolutions generally come in 3 basic flavors, going from past to present they include VGA (640×480), SVGA (800×600) and XGA (1,024×768). XGA is currently very prominent with new projectors, however with presentation graphics an SVGA resolution may suffice. 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. Some projectors support a number of different resolutions, but the “default” is usually referred to as its native resolution.
For on the go projector presentations, brightness (measured in lumens) is one of the most important projector parameters to consider. Lumens measure the intensity of a projector’s light and the environment in which you use the projector is a major factor in deciding how many lumens you need. Large sized venues or semi-lit screening areas require a very bright projector, something over 4000 lumens would not be unheard of in this situation. 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. The term ANSI lumens refers to a uniform standard of measuring lumens.
You might hear about “throw distance” as well, this one is pretty simple; it refers to the actual distance that your projector will be from the screen. If you will be relatively further than 15 feet, you’ll have to ask for a “large throw” lens. For power point projector presentations, short throw projectors can be advantageous because you can place them at the front of the room near the screen (behind the presenter) and make your presentation without any obtrusive shadows on the screen or distracting projector lamps glaring at you.
Another important detail for power point and graphic presentations is the compatibility of your projector and computer. Usually you won’t have to worry too much about computer – projector compatibility as these devices adhere to some general standards now days. In any case, still check to make sure you have the proper ports and cables at your disposal to connect your devices. Again, when everything is compatible, that’s one less thing to worry about.
When you look at a variety of projectors with your needs in mind, you can make an informed decision. Believe it or not, you can find some of the best deals on power point projectors on ebay through projectorselect.com, see it for yourself.
