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 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.
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
How bright is the room where will the projector 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.
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
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.
