With so many options to choose from, buying a presentation projector for an upcoming graphic presentation can be a difficult task for someone who is non-technical. With it’s focus on your needs, this article was written with the beginner in mind. 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.
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.
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. Many projectors can operate at numerous resolutions but they always have a default or native resolution.
Measured in Lumens, brightness is a very important specification to consider in your projector search, especially when looking for a portable projector to make presentations on the go in often less than ideal locations. Because of the significant influence of the screening environment, ambient light and projector brightness on the visual appeal of your projector presentations, lumens (units for light intensity) are an important spec to look at when choosing a projector. For larger sized audiences in a semi-darkened room, you will probably have to go with Ansi lumens measurements of 5,200 lumens. With a much smaller screening room that can get completely dark, you could make a clear, crisp presentation with a projector that puts out only 1,000 lumens. When you see the term ANSI lumens, just know that ANSI is a common standard method of measuring lumens.
“Throw distance” is another term of interest, it refers to the distance you can have the projector from the screen with a focused picture. Projectors that reside significantly further than 15 feet away from the screen typically have long throw or large throw lenses. 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.
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. You should obtain your computers native resolution and write this down, note if it’s SVGA or XGA, also you’ll need to know the connection standard by which you can connect computer and projector, many projectors have a computer in port and with the common standards in place, this isn’t much of a worry. In any case, still check to make sure you have the proper ports and cables at your disposal to connect your devices.
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. Now that you know all about some of the basics about Power Point Projectors, you are armed with the knowledge you need to visit sites like ProjectorSelect.com, browse and compare the multitude of projectors available. Good luck.
