Before buying a projector, you must first determine its purpose. Do you intend to use the projector to project a movie or a cricket match at home or in the apartment complex lawn, or do you want to use the projector to project presentations at office. As listed below, projectors come in two categories.
Types of Projectors
Multimedia Projectors: A multimedia projector is designed for business presentations.
Home Theatre Projectors: As the name suggests, the home theatre projector is ideal for home use. Make sure you check the aspect ratio of your projector before purchase. The perfect aspect ratio for a home theatre projector is 16:9.
The three projector technologies existing today include digital light processing (DLP), liquid crystal display (LCD) and liquid crystal on silicon (LCOS).
Here are a few other factors that you must keep in mind while selecting your projector. These include aspect ratio, resolution, contrast ratio, brightness, throw distance and positioning, installation, weight and portability. The native aspect ratio of your projector is the width to height ratio of the image. The resolution is the number of pixels that your projector displays. A high resolution is always better than a low one. The lumen rating refers to the brightness of your displayed image, while the throw ratio implies distance between the projector and the image on the screen.
