For a professional presentation
When setting out to create the ideal presentation the quality of the projector and associated equipment is of the utmost importance if you want to impress your colleagues with a compelling and professional presentation. The correct choice of projector, screen and software is vital.
Where some still prefer the traditional OHP (Overhead Projectors) many, especially in an office situation, are opting for a combination of the latest software and projector technology to give the impact required in today's competitive work environment.
In terms of software the most commonly used is Microsoft's Power Point. First coming to light in the mid 90s Microsoft's state of the art package provides the user with all the tools needed for a lucid and exciting presentation. If you happen to use Apple's Macintosh operating system then their Keynote software is also extremely useful when preparing professional calibre presentations on your own PC.
Often a prime consideration when purchasing a projector for use in presentation is the mobility of the product. Whereas many large conference halls and auditoriums will have there own specially designed system tailored to their space and professional needs you may need to consider a portable projector to help you transport it from venue to venue.
Brightness & Resolution
Depending on the space you are required to make your presentation in there are a few important factors to consider. Firstly, the brightness of the image as there is no point in having a crystal clear image if nobody can see it! Therefore it is imperative that you get the level of brightness correct. A projector with an ANSI lumen rating of around 1000 should be sufficient for a smallish space such as an office with larger space needing more power. Retailers and manufacturers can guide you on the exact levels needed. Then there is resolution to be decided upon, the higher the resolution the more detailed the picture. Most digital projectors work with either XGA (1024 x 768) or SXGA (1280 x 1024) resolutions. It is advisable to match your PC's resolution with the resolution that the projector works at using a program such as Windows, having said that the problem can be avoided at an earlier by matching the initial purchases. Further to this the quality of screen and the level of ambient light also have a significant effect on the picture quality.
According to budget there are two main types of projectors on the market today. LCD projectors are usually slightly cheaper and give good sharp colors with a high level of brightness. Amongst the most common problems with this type of machine is a lack of contrast and a kind of cell 'structure' effect. The slightly more expensive DLP projectors avoid many of these problems but are perhaps not quite as bright. With both systems it may be worthwhile getting a demonstration from the retailers.
