Portability, image quality and connectivity are the three most important questions to ask before purchasing a projector for your business, according to Consumer Electronics.

The leading consumer electronics website published a list of key factors to consider before making a purchase - a useful guide for those wanting to invest in a projector that is perfect for their business needs.

For businesses, data projectors are recommended above home entertainment projectors. Whereas home cinema projectors handle full motion video well, data projectors excel at displaying data images like PowerPoint presentations, spreadsheets, and PDF files.

Portability is another important consideration. The projector market now boasts models with sizes and weights ranging from small and light enough to fit in a brief case to large enough to be suitable for permanent installation only. While the former may not offer the same image quality, pico projector are perfect for work trips and use on-the-go.

Beyond size, understanding the specifications of each projector is important. In big spaces, the projector will need a large "throw ratio", while the light level in the room will determine the light output (lumens) the projector needs.

Finally, for businesses looking to work collaboratively, connectivity is key. Options such as VGA, DVI and HDMI cables, USB connections, and wireless capability allow multiple users to hook up to the projector.
