Making a choice
So, you have decided to take the plunge into the world of projectors? Whether your projector needs are professional, educational or simply for entertainment, there is a vast range of products on the market. On the surface, one projector looks much like another and it can appear incredibly difficult to make a well-reasoned decision. Further added to this is the fact that there are a multitude of projectors on the market ranging in price from under £100 up to the £10,000 and more. Bearing all of this in mind, you might reasonably pose the question of what criteria should you be using when deciding on which projector to buy?There are a few very important aspects to consider when analysing a potential projector purchase. Firstly, you should be clear on exactly what you are going to be using the projector for. For example, if your use is going to be mainly watching movies at home, then you should be looking at a projector with a fairly low brightness level. If you are going to be using the projector in a large space such as an auditorium or church, then a projector with a higher brightness level would be more suitable. Other important factors to consider include the resolution, the aspect ratio and the weight. Once you have established exactly what you are going to use the projector for, you can start to use the above criteria to rapidly narrow down the field of products.
Resolution and Ratio
These two aspects are important for ensuring that the size of any image that you wish to display is correctly portrayed. Most people should be fairly familiar with the idea of resolution. Put simply, the higher the resolution, the sharper and more detailed the image is likely to be. Resolution for projectors is measured in pixels. Most projectors will come with a 'native resolution', this is the setting that the projector is most comfortable working from. However, most of them can be used at higher resolutions if necessary. Note that this would have an effect on image quality.Projectors come in a wide variety of resolutions ranging from 800 x 600 all the way up to 2048 x 1080. You should make your choice of resolution based again on what you are likely to be using the projector for. For good all round use, 1024 x 768 has emerged as a popular favourite, but you could get away with 854 x 480 for basic home cinema requirements. If your product is to have a practical application, i.e highly detailed drawings or detailed photography, then a resolution of 1920 x 1080 may be more suitable.
Quickly dealing with aspect ratio, you will observe three common projector ratios: 4:3, 16:10 and 16:9. 4:3 is the standard ratio for standard television, 16:10 ratio has been designed for widescreen computers and 16:9 is recommended for movies or high definition content.
