    There are mainly two types of projectors:

    - Liquid crystal display (LCD)
    - Digital light processing (DLP)

    Both types of projectors are almost of same prices but liquid crystal display projectors have better sharpness whereas digital light processing projectors have better depths of their dark colours.

    One of the factors you should look upon while selecting a projector is its brightness. You can measure the brightness of a projector in lumens. In order to get a brighter and more lively-pictured projector then you need to select a projector with more lumens available. Higher lumen projectors are mostly used in rooms or places where there is more light. The range of lumens in a projector is 1000 to 1000. For rooms which are smaller and with less light, you can choose projectors with under 2000 lumen range.
