The popularity of projectors has risen greatly in the past decade. Nowadays, projectors are considered as one of the best media tool to share information through presentations. Projectors are characterized by resolution, brightness, weight, lamp life and contrast; all of these characteristics make the product what as good as it is. Whether your interested in an LCD projector for your home or office, or for the next great sales presentation that you’re making on the road, knowing some basic information about the differences and features available on today’s digital projectors will help you make an informed decision about which one would be best for your requirement. Here are the things you need to be more familiar with before buying LCD Projector: Resolution measures the amount of detail that can be seen in an image. It is the number of ‘pixels’ that the projector is capable of displaying. Pixels are the individual dots that make up the image on your computer. SVGA, XGA and SXGA+ are terms that describe common resolutions used by computers and projectors. Brightness is a key component to the visibility of your projected image. You want to make sure that the projector you choose can produce enough light to display the images onto a screen across the room. Brightness is measured in ANSI lumens and the level of brightness you’ll need depends on how you’ll use your projector, how dark the room will be, and the projector’s distance from the screen. Contrast Ratio is a measure of a display system, defined as the ratio of the luminance of the brightest color (white) to that of the darkest color (black) that the system is capable of producing. A high contrast ratio is a desired aspect of any display, but with the various methods of measurement for a system or its part, remarkably different measured values can sometimes produce similar results. Weight may depend on your needs. If you are always on the go, you might consider choosing a light or portable one however; if you are going to use the projector in a specific place and have no need to move it around, weight is not an issue. Projector lamps, also known as projector light bulbs or projector bulbs, are one of the few user replaceable projector parts. There are several different projector lamp technologies of differing wattages. Be sure your projector light bulb matches the one you are replacing as each projector is designed to use a specific type of lamp and a specific wattage. Connectivity is important when shopping for one. This is especially necessary if you are going to use a variety of video sources and PC inputs. With multiple connectivity, you have the flexibility to connect it with the type of media that you want to use. When assessing the connectivity feature of a projector, it is important to know how it will be used, as well as to what equipment it will need to connect. Knowing what your LCD projector might be used for will give you a head start on the necessary requirements for the device. Most projectors use LCD technologies that allow them to be used on many other electronic systems such as; pc and laptops.
