Hiring a Data Projector

Get to know the specs

There is a wide range of data projectors currently available on the hire market each with its own particular specifications and suitability for certain applications. The FRASP guide to hiring a data projector details the main specifications of data projectors so you can be sure that projector you are hiring is perfect for the intended use.


Data projectors work by taking a digital image and projecting it as a highly focussed beam of light onto an appropriate surface. There are a number of specifications that dictate how effectively a particular data projector will project the image, this guide will run through these specifications so you can always hire the most appropriate projector for your event.

ANSI Lumen Rating – The lumen rating of a projector is a measure of the brightness of image it is able to display and as such how it performs in certain ambient light conditions. The higher the lumen rating the better the projector performs in brighter ambient light conditions.

  • Up to 1,500 – Best results achieved in near total darkness using a small projection screen and displaying images with large bold images or predominantly text.
  • 1,500 – 4,000 – Able to display images in low to moderate ambient and artificial light conditions data projectors within this range of lumen ratings can effectively display precise and detailed images with small text. They can also produce better image quality on larger screens of up to 2.5m.
  • Over 4,000 – Data projectors with a lumen rating of over 4,000 ANSI Lumens are capable of producing high quality images in venues with high ambient light levels or outdoors. They can produce high quality reproductions of very precise or detailed images on large projection screens of over 5m in width.

Contrast Ratio - The contrast ratio of a data projector is a measure of its ability to block out the lamp light to produce black and darkly coloured areas of the image. The ratio is a comparison between the brightest and darkest images a projector is able to achieve and the greater the ratio the better the projector.


E.g. A projector with a contrast ratio of 400:1 is better able to produce produce black and dark colours than one with a CR of 200:1.


If you require a data projector that is able to produce images of particular sharpness with depth in the black and dark colours a data projector should have a contrast ratio of over 400:1.

Resolution - Pixels are the minute blocks of colour that digital displays use to build up an image and resolution denotes the number of pixels a hire data projector is able to project onto a screen. The more pixels a projector is able to display the sharper the image that is produced.


Most hire data projectors are capable in projecting in two resolutions, SVGA which creates an image of 800 pixels x 600 pixels or XGA which produces a sharper image of 1024 pixels x 768 pixels. Both these resolutions are supported by the majority of laptops.
