CONFERENCE & PRESENTATION

How to choose the correct projector for your needs

Its 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 brighteness (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 defi nition. 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 defi nition 

1080p resolution projector.

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 chose 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.

Brightness:

How bright is the room where the projector will be used? Can the lights be 

turned down/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.

Contrast Ratio:

This is the measurement between the black and white images projected on 

the screen. The higher the ratio, the greater 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 specifi cation of machine 

required.

Distance from Screen:

To ensure the projected image fi lls your screen you will need to check the 

projector’s 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.
