This makes it possible to project an image that looks as though it is being projected by a huge screen onto a smaller flat screen. Projector technology allows for many different types of displays, ranging from simple text on a paper to a complex video animation. Projectors are classified by their capabilities and technology. They vary in terms of viewing angles, refresh rate, number of pixels per eye, resolution, and brightness and contrast levels. The number of pixels per eye refers to the number of pixels the projector uses for each display. - the fewer the pixels, the more detail is displayed. When choosing a projector for your presentation, you will want to pick one with the right number of pixels per eye.
The first thing that you need to consider when looking at a projector is where you will be using it from.
