Digital technology has been greatly responsible for the invention of electronic equipment for use in our homes and offices for work as well as for entertainment.   The projector is one such piece of equipment that is put to good use today for the purpose of watching movies and slides especially in the presence of a large audience, by projecting an image on a screen in response to a signal received from a DVD player or computer.


In the early days   it was mostly used for seminars and exhibitions to project statistical data, graphs and documents etc. to make a presentation clear and visual to the audience. Today, most people use Home theatre systems consisting of a projector, and screen to view movies in the comfort of their own homes instead of going to the cinema. With different types of projectors being   available in the market, the craze for home theatres has resulted in many people being on the look out for suitable projectors and projector accessories to suit their needs and their budgets.


The most popular of them is the Front Projector which is usually placed on a shelf or mounted on the ceiling for easy viewing. It is more important however to look for a projector that is not too complicated but is of good quality as far as images and brightness is concerned. Modern projectors use technology such as LCD, DLP etc. to provide us with the best performance although they too have their own pros and cons.  One disadvantage of a home theatre projector is that it produces large pictures on the projection screen  which might not always suitable for small areas.


A projection screen has a completely blank surface which is usually white or grey. This  screen can be a permanent fixture as you see in a cinema, a painted wall or a mobile piece of equipment that is portable and can be carried anywhere for a conference or exhibition. It is important to check the size of the screen before buying since screen sizes vary from 14 inches to 15 feet and the one you choose must be in keeping with the dimensions of your room. The aspect ratio of the projection screen must also be taken into consideration with the most popular being the 16:9 compared to the normal TV screen ratio of 4:3.


Most people will not give much thought to the projector mount  which is silly because itís the only thing that will keep the expensive equipment from crashing to the ground. The mount you choose to place the projector can be a tabletop, wall or ceiling; depending on the weight of the unit and how balanced and stable it is when mounted. The surface area of the mount must also be taken into consideration because too much surface can trap the heat and damage the equipment. If a ceiling mount is preferred, decide whether you want it flush with the ceiling or dropped down a few inches, depending on the size of the screen. 


Apart from projector mount, there are   projector accessories that come with LCD projectors. These include projector cables that enable the unit to be connected to a computer or video, projector remotes, to help screen adjustments, lenses for clearer display of images, projector lamps that are inbuilt but has to be replaced, and a projector case to store the unit when not in use. Itís up to the buyer to decide what is important and what is not.
