Projectors have become an imminent part of offices, schools and colleges. The picture that you are projecting may have light and dark images. The contrast ratio is basically the difference between the light and dark which is expressed by a number. It is the comparison of luminosity between the brightest white and the darkest black on a screen. It basically means the number of dots or pixels used to display an image. The higher the resolution, the clearer the image. The difference between a high-resolution image and a low-resolution one is that there are more pixels in an image with high resolution. This results in a crisper and cleaner image. This is usually indicated by a number combination such as 1920 x 1200. This means that there are 1920 dots lined horizontally and 1220 dots lined vertically across the display.
