Hiring a data projector is one of the options available to cater for your
IT display requirements but it is worth being aware of the terminology
describing projector specifications to ensure you get the best unit for
your particular event.
Brightness: The brightness of a data projector is measured in ANSI lumens
starting between 1000 and 1500 lumens for a unit suitable for simple office
or boardroom use, which is generally more than enough assuming the rooms
lights can be dimmed and there is little or no ambient light. For more
brightly lit venues a more powerful data projector of between 2000 and 3000
lumens may be more suitable.
Resolution: Resolution describes the number of pixels the projector is
capable of projecting onto the screen. The higher the resolution the
sharper the image appears on the screen. The majority of data projectors
fall into one of two resolution categories – SVGA (800 x 600) and XGA (1024
x 768). Most computers also transmit an SVGA and XGA signal.
Contrast Ratio: The contrast ratio of a data projector describes its
ability to block out the projection lamp light. This translates into the
depth of the black parts of a projected image. If you require an image of
particular sharpness then contrast ratio should be a consideration.
When using a projector it is recommended you use a projector screen to
ensure the projected image is of a high quality. Projector screens are
available in many sizes that are suitable for any venue. Projection screens
are available with front or rear projection surfaces.
Front projection screens dictate that the projector is positioned in front
of the screen and this may be an issue for events where there may not be
room in the audience to effectively position the projector or where
aesthetics are a consideration. In which case a rear projection screen may
be more appropriate and this allows the hire data projector to be
positioned behind the screen. Be aware though that although the projector
is behind the screen the distance it has to be positioned from the screen
will be the same. As such if there is insufficient space behind the screen
to effectively position a standard projector then a short throw hire
projector may be necessary.
Other aspects to consider when deciding on the most appropriate projection
screen for your event are –
Size: Be aware of the height of or any fittings in the room in which the
presentation is taking place that may restrict the installation of a large
screen. The screen size may be 8ft square, but the total height of the
screen including the legs may take the total height up to 10 or 12 feet.
Front or rear projection: Front projection describes the positioning of the
projector in front of the screen and as such will only require a normal
projector screen. Rear Projection describes the positioning of the
projector behind the screen and requires a specialised screen type. Rear
projection allows a reduced distance between screen and projector allowing
for a thinner profile and reduces the likelihood of people moving between
the screen and projector, disrupting the image.
Once you know the projector specifications and screen for your event
approach a professional audio visual hire company to discuss their range
and prices. It may be the case that your budget is insufficient to cater
for the size projector you require and as such you may need to alter your
