Finding the Perfect Computer Projector for Your Power Point Presentation
For someone who is not tech minded, purchasing a power point projector can be overwhelming with all the current choices. That’s why this article was created to give you the simple, basic understanding you need. With all the buzz words and projector jargon out there, your knowing the basics will be a great help to you in your projector search.
Whether you view an image via your laptop or a presentation projector, that image is comprised of pixels. 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.
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). You may even hear about SXGA (1,280×1, 024) that will give you even greater resolution, but tends to run on the expensive side. 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. 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. If you plan on making your presentation in a fully or semi lit room or just a huge venue for a large audience, you will need a very bright high lumen projector, something on the order of 4000 lumens or more. Small audience—dark room—1,000 lumens. The term ANSI lumens refers to a uniform standard of measuring lumens.
Another important factor to consider is “throw distance”, this is the distance that your projector should be from the screen. Projectors that reside significantly further than 15 feet away from the screen typically have long throw or large throw lenses. With a short throw power point 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.
Connectivity is very important when interfacing your computer to a projector. Making sure that you have compatibility is important to someone who does power point projector presentations. Usually you won’t have to worry too much about computer – projector compatibility as these devices adhere to some general standards now days. Despite well heeded standards, it never hurts to check or double check compatibility between a projector and your laptop. Make a note of the ports and connection interfaces. 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. Ebay believe it or not is one of the best places to find both new and used power point projectors.
