It's all about resolution, brightness and the presentation conditions.

Although choosing a projector can be complex, deciding what kind of machine you need should be a relatively simple process, involving six areas of consideration: room and screen size, resolution, technology and brightness (lumens) and room conditions. Other factors such as contrast ratio, colour reproduction, inputs needed and extra features will also play a part in your decision.

Resolution:
The higher the resolution, the greater the definition. Most modern laptops are now XGA or higher and it is advisable to match the PC and projector if possible. This will provide greater clarity. If you are looking for the best quality and want to watch DVDs or Blu-Rays you should choose a high definition 1080p resolution projector.

Brightness:
How bright is the room where the projector will be used? Can the lights be turned down or blinds shut? This will determine the ambient light in the room and how bright the projector needs to be. The brighter the room, the brighter the projector will need to be. The brightness of lamp-based projectors is measured in ANSI lumens. LED projectors are measured by LED brightness.

How will the projector be used?
Does it need to be light and portable for off-site meetings or installed in the boardroom? This will help you choose between mobile or ultra mobile, desktop or installed projectors. For basic PowerPoint presentations SVGA and XGA projectors are good all-round cost-effective projectors. Boardrooms and larger meeting rooms might need a larger screen and a higher resolution projector.

Many projectors are compatible with optional wireless devices enabling you to connect and display presentations wirelessly from a laptop, PC, Mac or even your mobile.

Contrast Ratio:
This is the measurement between the black and white images projected on the screen. The higher the ratio, the greater the density of these two colours, which in turn gives the appearance of higher screen brightness. Look for a projector that gives the greatest contrast ratio for the specification of machine required.

Distance from Screen:
To ensure the projected image fills your screen you will need to check the projectors throw ratio. This is simply the distance the projector is placed from the screen divided by the width of the image it will project. Short throw and ultra short throw projectors can be installed very close to the screen. Mobile, desktop and most home entertainment projectors must be sited further back.
