Business projectors don't have to be just the equivalent of a home theatre of the office or conference room; rather, knowing and understanding a bit more of the different types and their key features/ functionality can enable them to be used as powerful business tools, says David Stone in eWeek.com.

According to the article, one of the key features to consider is the "throw" of the projector ie. the distance of the projector from the screen [choose between standard, short throw, and ultra-short throw]. Secondly, consider how shadows can be avoided; thirdly, where do you want to place the projector [table top, rear projection; table top, front projection and on-the-floor projection].
