Projectors are the best to show your presentations.
There are however a number of important factors to consider before installing a projector. The majority of projectors can take inputs from both a PC and video sources, such as DVD player of tuner box. But most of them are also optimized either for PC use or for a home cinema setup. It is very seldom that these home theatre projectors excel at both. Each home cinema setup is unique, and therefore it is necessary to do some research before buying the first best video or computer projector. Projector reviews are usually a reliable source of information, and can be found on the Internet or in magazines. You can also speak to a representative at your nearest supplier of home cinema equipment.
There are a few questions you should be asking yourself though before buying yourself that long awaited video projector.
Screen size: If your preferred projector cannot produce the correct size image, it can be eliminated from the list of options straight away. So it is one of the most important places to start.
Brightness: Many people assume that the picture quality is better when the image is brighter. This is not the case. Brightness helps to provide you with a clear image, but it should not be the deciding factor when choosing a projector.
Contrast: This is one of the main factors to consider when deciding what home theater projector to buy. The perception of depth in the image is increased by a higher contrast, and this will cause subtle variations in color to become more evident.
LCD and DLP: There has been an ongoing battle between these two technologies for a while. Both LCD and DLP evolved immensely over the past few years, and the gap has become less evident.
Connectivity: Nearly all projectors being sold these days come with the basic connections such as VGA, S-Video and Composite.
Aspect Ratio: Almost all the home theater projectors that are being designed for home cinema are 16:9 format.
Progressive scan: Most TV signals are being sent in “Interlaced Scan" format. Progressive scan converters take an Interlaced Scan formatted signal, and convert it to a superior signal.
Resolution: The resolution you decide on will determine how many pixels your video projector can display at a time. This will in return affect the smoothness of the image.
Bulb life: replacement bulbs for projectors are quite expensive, so therefore a long bulb life would be beneficial. 2000 hours is more or less average.
In the end each one should decide on a home theater projector that is right for them, but taking the above mentioned factors into mind.
